Lock down those TPS side screws. Where is the "throttle adjusting screw" ? The below graphic is for the OHMS test, but in fact this same drawing showsyou, what pins to test for the live voltage tests. to be opened up to compensate. (ground) It tells the ECU how far open the butterfly in the throttle body is. Gray/ yellow 0 Volts. or open 5v wire (like 5vdc is dead on the 5v pin of TPS, 5vdc gone is bad ECU ) The throttle position sensor (TPS) is a device on the engine that detects the position of the throttle plate. what do you mean? So, I took the TPS out of the throttle body, and plugged it into the harness and . Yes, setting up 94 thou , is a pain, no feeler gage set has this size. can cause a code to set. Adjust the TBI. The switch most work right or many features fail, liketiming freeze(service) or idle controls are dead or EGR fails to work, and the ISC goes dead. MPI is 16v Multipoint Injection motors, and has no Dash pot steps, or device. Note the reading on the multimeter. Where To Buy The TPS And Save. (Infinity) Any time the IAC valve is replaced, this learn procedure should be the cold start fast idle device ) The VSV (vac. Not my write up,but found this on anothere forum : most of the 80's model GM TPS sensors were adjustable. (after the key has been off for at least 10 seconds). Remove the AWS hose from the inlet pipe to access the TPS sensor on the firewall. See Full PDF (8pages) factory CALIBRATION. Best place for asking questions is FixKick forum. Aftermarket camshafts with lots of duration or lots of overlap tend to lower the November 11, 2019 by Jason. The sensors all eventually wear out and the throttle angle pins starts glitching or has dead spots. the vacuum level to drop at idle, which will require the IAC or throttle blade In this case well be taking voltage readings directly from the connector at the TPS using a Digital Voltage Meter. Adjustment is made by rotating the TPS driver slightly clockwise to increase voltage. (cut means broken,cut or corroded) STOICH: (means perfect fueling) that happens in Closed Loop mode of the ECU. Place the TBI assembly in a suitable holding fixture to prevent damage to the throttle plate and injector electrical . Adjustment is not possible. The sensor detects the opening and closing of the throttle valve and feeds that info to the vehicle's computer. Estimate does not include fees and taxes. amount of air to maintain the preset idle speed), There is increased load Same rule, if somenincompoops, fiddledthe TV valve stop screw, all bets off, this folly, must be corrected now. ( not 300 or 50 ohms or less,or some other value , but trueinfinity). Omg what is a Carb? (this switchnever produces 0 ohms, but does go below 300 ohms for closed , ECU expects less that 500 or less, we think) The J18 engine first removed this device and on all future engines. replacing the IAC valve, you should check all of these possible issues first. It allows air to bypass the throttle plate. (or the wire on this pin is shorted to ground or to the power pin A) Ground the black multimeter test lead on the battery negative (-) terminal. One example of this is when the engine is modified, or a different (the red numbers below , are odd GM /GEO numbers, I ignore them) All sizes are in inches (imperial USA inches) times 25.4 for mm. TPS switch open, LIMPHOME IS IN EFFECTcar starts, no idle controls, at all , ISC will be dead. There are three pins in the connector, 5V, Ground, and Sensor. or even jam the throttle). It should be mounted to your throttle body, which is on top of your engine. METER MADNESS: adjustments dont (factory set) (the bracket does come off easy). Buzz words: Code 44s, and timing freeze fails to work (the jumper). this car runs like a rape date-will burn first and second easy and its an automatic. When they do, they usually freeze up or get stuck in a fixed position. The idle switch must be closed and near 0v running or the timing freezeor EGR, ISC will fail to work and DTC 44s happen. ), blocked from anyone touching it !!! The wires related to TPS, were cut/shorted to the ECU or TCM or Cruise controller, or shorted by theAudio/Alarm installer from HELL! Loosen the jam nut and unscrew the throttle stop screw all the way so that the throttle blade closes fully against the throttle body itself. Turn the throttle down by tightening the TBI's screws. So that means if say , engine power is lost andnever catches up?, then the TPS is NOT THIS PART BAD. aka, set at threshold of closure. Test 3: Pin B is throttle angle, or a.k.a. These simple tests follow below: TheDash Pot must be retracted, when stated. 1,2,3,4, bottom up. This is caused by worn carbon on the above rings, end of life. FYI: The engine is.030 over with a EFI cam and 9.5:1 compression with aluminum 63cc heads. Adjusting the TPS switch is the ACT of Calibration. None of the 3 throttle cables: 1-driver, 2-A/T kick down or 3-Cruise cables, interfering with the throttle valve. If the meter does not read 5 volts, the TPS is bad. If you also look carefully the TV throttle stop screw isblocked from anyone touching it !!! The idle switch (pretend 91 G16a) shows infinity ohms with throttle open then when .016 gap (.4mm) happens the OHMS drops to 500 or less like a shot, some do this at 1000 ohms, we calibrate near 500 but is crude, just get it below 500, a touch. Photo #2 (early TBI) this is a real photo. This function has the same parallel to the high speed Accelerator pump device inside many carburettors. If not, remove it using a sharp pointed tool. BATTERY from A to D (plus on A) connected directly then add a resistor from B to D(minus battery side) this simulates a real ECU load. Holding it open by hand is no fun with DMM meter in other hand unless you are octopus man. Now I cant get a reading over 1.20 volts at WOT. G16A. Make sure that accelerator pedal is fully released: 2. Put back to stock and sold. G16A TBI 8valve only device found on TB (throttle body) this device is only vacuum motor (servo) Just a diaphragm and spring inside. It can also be used with the cars ignition turned on but the car NOT running to check other data relative to the TPS. The ECM resets the IAC valve when the car is The TBI engine G16Adash pot devicemust be retracted first ! This is why the feeler gauges are used. Angleis never calibrated. In 1991 GM changed the throttle position sensor connector and there are two styles of EGR solenoid . TPS Adjustment procedure 2005-2010 XPs: By: commanderjjones aka Jerry _____ TPS = Throttle Position Sensor: The TPS is located on the passenger side of the throttle body. Idle switch OHMS. The ECU has a tendency to not see TP glitches (denouncing logic) and will cause hesitations, when advancing the throttle. This is the 89/90 steps for TPS calibration and idle speed, these 2 years are unique. Disconnect the TPS main connector , this connector has 2 other pins, for the injector , please ignore the injector pins.(red/yell). The Fast idle control features will fail, the Cut fuel and EGR may fail. Turn the ignition ON, but do not try to start the engine. Key off: This TPS was stuck in UNFLOOD mode, car will never start. Glitching= This means that the voltage or resistance is not linear at the TP pin (throttle angle) seen here as glitching open . (however an analog meter may see them or a graphic GMM may, and all scope for sure can). Remove grounding of the Not properly indexing the TV shaft pins to the TPS can cause TPS to stick throttle open. 3. Below are theactual FSM pagesfor TPS calibration: TBI 1991 and UP. about 50 ohms or near 0volts) OFF means the switch reads, Infinity. You need to back off the driver set screw 1/2 of a turn to set them properly. Pin B (TP) (see FSM here)( the normal voltage idling is0.6 to 1.5v) ( 2 nuts hold the bracket on, only) No dash pot. repeat them all. If it stays closed too long, the ECU will fight you, as you tip in the throttle , one of the most odd sensations in car, you will ever experience, here) Remove the air cleaner lid and the air duct leading to the throttle body using the Phillips screwdriver. You are cruising and you tip-in the throttle moreand it hesitates, then catches up! This is a bad TPS TP signal. Stick the pin in the center wire of the throttle position sensor plug. It also shows you how the carbon works, the Gold wiper device is missing here. connected, ground the diagnostic (ALDL) terminal (same as you would do to flash Now that youve installed the TPS following the directions posted elsewhere on the site, its time to adjust the TPS for optimal performance using either WinALDL software or a Digital Voltage Meter as shown below. DMM/DVM: meter set to 20k Ohm range: See Figure 2 above for pin locations. *(8 inches HG vacuum dose it) at nipple seen below. Push down on the throttle by hand until it is completely open and check to see if the voltage increases while pushing down on the throttle. I've got an '89 and used a scanner to find out my TPS was shot. (it will fail ! Remove the TBI using an Allen wrench. The Dash pot is on the lower left, clearly seen. This method is called GO, NOGO and CAL. Your Equinox's throttle body controls the amount of air that enters the engine. cant adjust a TPS sensor as far as i know, you can replace them, 1998 Dodge Dakota, 2wd ECSB, 318, M1 2bbl intake, 52mm TB, Taurus fan, Ford injectors, MP PCM, MPP mid-length headers and full exhaust, Hooker Aerochamber, DJM 3/5 drop. You need to back off the setscrew in the driver 1/2 of a turn to set the voltage properly. Never touch this screw below, the feeler is the Calibration tool . Lock down the TPS side screws. If unable to pull 6", be sure front TBI throttle stop screw is not limiting throttle travel. When driving the ECU may ignore the fast glitches but all get worse, in time, and if you see it glitching you know for sure that the duration can very (made worse) by the engine vibration Basically, the main cost involved in replacing a throttle body is the cost of the parts required to be replaced. (or cause bore wear) Suzuki has NO SPEC. Before calibration, there must not be thesegross errors: The TPS mounts to the TB (throttle body) side and measures TV actions, and reports them to the ECU. I cannot weld. The ECU can evenhunt / surge (wild RPM changes)at idle if this PIN C is not working or calibrated wrong. This program lets you connect your laptop to the ECM to conduct data logging sessions while driving the car. Never hot wire or ground out the ECU +5vdc(Ref) pin. With the IAC valve The TPS can be tested on a bench too. Michigan. Zero=zero opens the throttle vane 1.92 degrees when the lefthand stop screw is adjusted from 10 mV to 250 mV, however, the Motronic only reads 0.32 or 0.64 degrees. Do not turn the key to the run position, until the installation is done. ECU, engine controller unit (a.k.a. operated at normal road speeds (35mph or more). It may feel as though the car simply doesn't accelerate as it should, and jerks or hesitates as it picks up speed. Un-flood mode. This may be .045-.065 volts. operating temperature and then adjust the throttle stop screw in or out until (will cause , engine that loves to flood ,cranked cold) but does make calibration easy, sure (1/2 joking). The FSM instructions, are are linked in every section on calibation and does cover this step. Push the multimeter pin into the TPS screw and check the voltage. This method guarantees some tiny fractions of inches ( of over/under-travel.) Mine was 2.33 at WOT - So I loosened the torx screws and tried to adjust the TPS. Start engine and warm up sufficiently. The throttle stop screws primary function is to This fuel then makes its way through the system and could . even a $10 analog Walmart meter will work PERFECT here, no need to buy expensive tools to measure 5v and 300 ohms. The throttle body costs between $200 and $500, while the labor cost is around $50 and $150. I probe pin C ,key Onno start,, and the Dash Pot is holding the throttle open now, (if not fix that now) and the voltage is 0vdc, ( 0.5v) THROTTLE POSITION SENSOR (TPS) 1) Turn ignition on. I am not a body man. Threshold is setting it, just so the switch has just closed. We also have OE-level training and advanced diagnostics, including reset adaption, adjust/reset of the throttle actuator and EGR valve coding. a tad, so the TPS can move easy, and rotate. INDEX: (all G16 unless stated otherwise)All years are USA generations, not worldwide! Eg. on the left. AnyDMMs meter can be very slow reacting, and miss them.! They then have an idle speed air bleed that is end user adjustable. Or bad luck, fate, or ? Regardless of the side draft carbs being used, you must have 100% throttle rotation prior to installing the TPS. Ensure all vacuum components are functioning properly. so the engine idle speed obtains 550rpm in drive (auto trans) or 650rpm in See how to fix the folly of finding that the TV valve is not 100% closed and some one messed with that screw above. this gap and that is what I use for guide lines getting this correct. Step 1: Locate the sensor. Photo 5, do not attempt to do this. Now, if there's a problem, there's only two possibilities: [*] There. Select the configuration button. The Switch side Low ,will vary from about 20 ohms (50 ohms is par) to 300 ohms closed (experience) and then go to open circuit, very soon ,as you crack the throttle open just slightly. on the IAC pintle, or in the idle air passage restricting air flow, There is carbon buildup Parts cost somewhere between $98 and $133 while labor costs are priced between $61 and $78. Pin 4 +5vdc from ECU. To be quite honest, you dont really see many IAC valves fail. I use tinyalligator clipsto comment my DMM meter to the TPS male pins, or I remove old female pins from spare connectors to make up test wiring. Stuck at 0v means Pin A wire is cut or open or ECU pin A not at 5vdc, or the TPS is bad. If this pin fails, for any reason, TV cables (up to 3 cables) not set at10mm play, or TV boreblocked in carbon,these faults must be cleared first or theCalibration steps will all be wrong. If this calibration is done wrong the following may (will) result. diagnostic (ALDL) connector and start the engine. The connectors are held in place with locking tabs, so you'll need to use something like a flathead screwdriver or a small Allen key to release the tabs first. The throttle body injector Vehicles of a Vehicles helps control the throttle and maintain the Vehicles revolutions per minute, or rpm. (off topic ) (minimum air setting). well, one is ground , one is 5v, and TP is low volts) Its the gray wire, with no stripe.). The TPS can be mounted wrong, and blocks the TV open. (will not attain 500 ohms or less) (if 8v DP retracted) (even fails in hand removed? (no more Code 44s now !) The voltage will rise to at least 4v (5.2v max) as you advance the throttle, it must be smooth and linear, with no glitching. Consult the engine diagram that came with your vehicle for extra guidance. PattonMachine.com 2020 Patton Machine LLC. ignition in the off position, replace the fuel pump fuse. Disclosure: I am not a mechanic. This fact also explains why the GLITCH, if any, also causes the glitch to drop to zero volts. (DP = dashpot on rear of 8v TB), The TPS was calibrated, but not tested with all 3 feeler gages, 91+. ), Photo #1:(aka. (I recommend testing it before calibrating the sensor ) The TPS can fail this way: Throttle body INJECTED with just 1 injector. Then the ECU causes a hesitation when you demand power. (22 is stuck low) The screw is set with very tough loc-tite. Rotate TPS CCW , very gently and get the TPS switch to just close, just barely. Test the voltage of your TBI using a multimeter. Tips for adding power to a throttle body injected (TBI) Chevy 305, 350, or 454 V-8 engine. TEST 1: Checking The Throttle Position Sensor (TPS) Signal. ), Side issue? TPS= Throttle Position sensor, or TP and Throttle Position , on newer cars 96+ it is called a Throttle angle sensor. Locate the TPS on the throttle body near the air intake hose. First trouble maker #1: The DP or Dash Pot. M/T = Manual transmission, A/T , yes, automatic (this is all ASE /SAE jargon. on second gens they can be adjusted let me find the thread. any cars TPS could be made to be adjusted, but on 2nd gens its not necessary, i got an 88 gmc jimmy 4.3l i just put on a new tps how to i check the volts someone got a step by step to what to do to set it right. This mode of running is very rich fueling (and very crude) and the CAT converter will overheat. The POT side TP SIDE: 16 valve MPI only. (keyon or off , not started) WOT is about 3.5v or more at the TP pin , and cuts all fuel , cranking (its a feature set on all EFI 1989 to present). Standard Ignition 3 Terminal Connector - S674. See the schematics here. Diagnostic Trouble codes: There are exceptions to that. 1) or potentiometer, or variable resistor. And cut fuel mode. Off car, you see the plate is not closed or is full of gunk blocking it open. 2.Misadjusted or bent throttle linkage.You don't know what was done before you got to it. To adjust the throttle position sensor (TPS) of the Vehicles you must remove the Vehicles and alter its makeup slightly. (and patience galore) Scope on pin B . The 4l60e will not respond to manual shifting like the old non electronic . To start with, turn the key to the on position and then find Go EFI Tuning on the main menu and press enter. 6932 Views 1 Reply 2 Participants Last post by Matt_vs_YJ, Aug 7, 2008. There are Never adjust the painted or capped off,throttle stop screw, for any reason. If you have a scan tool, I recommend allowing the engine to warm up to This tests can find a bad throttle angle sensor portion. Trouble code definitions. Begin tests: If you get a Check Engine light error indicating that a TPS failure, it is most likely caused by not having the TPS driver nut in the correct position. Pre-conditionals: (TBI G16A) If the TPS switch willnever close , even with the TPS completely removed from the TB, then the TPS is bad. Unplugged (not connected, testing) The 3 video tests (mp4) disconnect the IAC electrical connector. slack 10mm (7/16 inch) ( Up to 3 cables on A/T cars and cruise opted engines. On a 100% factory stock engine, you should never (suck means, use vacuum hand pump tool) or remove theDPwith that single stud screw. (but can if the ISC goes dead and other failures, prevent air flow to the engine or very weak fueling as this idle switch will shut down, the ISC) By the way, if idle speed is out of control ?,with the switch closed (0-volts) is coveredfound here. Once the driver is properly positioned, tighten the Allen screw to lock it in place. Key ON. This is the Fast ohms tests, unplugged tests. DTC 44 , and 45 ( 45 is stuck at ground , very rare this , is a harness short) The 8v is aTBI, throttle body injectiona.k.a. plugs. The TPS is now calibrated and validated. { FSM is Factory Service Manual } The TBI only, Dash pot, has a spring inside, andpushes outward that plunger by default, and holds the throttle open with keys in pocket! This page covers calibration and testing , on car or off, volts and ohm methods. if this pin drops below 4% throttle angle (below about0.2Volts) driving, you will getDTC codes 21/22 errors. Car won't accelerate, lacks power when accelerating, or accelerates itself. the TP pin. Now press the accelerator pedal all the way to the floor and hold it there until the Dash Display stabilizes with the Wide Open Throttle (WOT) percentage reading. If it does not vary in this range or has glitches or has dead spots, it is bad. How the TPS is used on a cold engine veries by car maker (ECU tuner), my whole pages covers only a hot running engine. 1991+, Graphic 1: You can do on car voltage tests, or simple ohms (resistance )test. All EFI engines like this go lean if the driver punches the throttle, all do (dead TPS), ( due to that slug of air is INSTANT) then the AIR meter sees the change late. (A/C fast idle), If not closed this idle switch, at idle the, if set (closed switch) to far into the TPS range, then the car , will have TIP-IN bogging. Unfasten the hose from the pressure sensor and remove the bottom bolt of the TPS sensor with a socket wrench. There's nothing to adjust. Tip-in as in your right foot tips in the throttle and engine hesitates a bit. November 11, 2019 by Jason. Remove cap from ported tube on rear TBI and connect manometer (J-23951). The TPS is just a variable carbon resistor inside, no magic or electronics, just carbon. Please send photos, relevant images associated to your classic car parts order. Very bad that. The code that showed up was P2135 which indicates a throttle issue. The purpose of this page, is to save you $250 for a new sensor and show the test and calibration steps. A Missing Dashpot on G16a engine. electrical testing means. is adjusted incorrectly (throttle resting closed too much), There is a mechanical Turning the TPS down may help improve the way your Vehicles runs, but if you turn it too low, your Vehicles may not start. they are set loose per the FSM. this would result in it getting wedged/stuck closed in the throttle bore), some Then select the Sensor Data button which will also show the TPS Throttle Percent position (yellow block/red arrow). ECM or PCM) (takes human testing to find this flaw, the ECU is very dumb here), Warning,(TPS calibrated to open late) air will always be allowed to enter the engine around the throttle valve. Voltage Method using a Voltage Multi-Meter (VOM). (just harnesses, if lucky). The TPS mustnever interferewith the TV or the opposite. ( I corrected and error here.. shame on me) : more to allow more air to enter the engine. PinB(TP pin) below, the voltage will very, for near 0v to near 5v, as the throttle is advanced. Keep in mind, when you set the.016setting (example) you then remove the feeler , and the throttle retracts .016 and you get a solid repeatable less than 300 ohms each time. There is little to no adjustment on the TPS assembly, 2. (use a 6v, 9v or 12vdc battery as your supply , or a 5v power supply , really 3 to 12vdc works. ) Insert a safety pin into the 3G connector on the voltmeter, sliding it between the rubber seal and the electric wire. The IAC valve cannot be tested using conventional 1: The end to end ohms on your POT must be steady at all times. This was. The 89/90 applies but the stop screw has special rules and steps for calibration and idle speeds. The throttle shaft is somewhat flat at that point. but at with the pedal to the floor, it only goes to 3.9v (the old sensor did this too, probably didnt need replaced.) Theangleside never sets idle speeds, ever. My broken TPS, internals,hackedopen. '96 ext. I have a question: if my tps Is bad and i Need to replace, can I get another cars tps? If you do, the next step will address in the error message. Too late TPS idle switch opening. 1 Throttle Angle Pot. The cables must never be tight and holding the Throttle valve open (TV) at all. The pin 3 throttle angle varies from about 1v to 4v (non critical) but must be linear in action (foot throttle) and not glitch. (aka SPI ,er, single point injected, bla bla) Pin 2 Idle switch out Blue/white (0v when at idle 5v off idle ) SomeGM booksshow pin 1 as 5v, this IS WRONG. The TP Angle pin carbon section inside, is worn as all do , eventually), Last 1991+ 8v TBI, and newer TPS Calibration procedures, packed in GUNK causing TV to not fully close. Myths: =for Potentiometer,or variable resistor. There is a vacuum leak Replace the TBI by placing it back in the engine. (wild jumps or drops in voltage) The TP pin pin can do that (DTC #22) and is a bad TPS. You will need a couple of paper clips or pieces of thin solid wire to reach into the back of the TPS connector when its plugged into the harness. The TPS should read between 4.0 and 5.5 volts. Hold the TPS in place and tighten the retaining screw with the Phillips-head screwdriver. This TBI 8valve device (back side of Throttle body) must be retracted someway to do the TPS calibration. Verified Purchase. Figure1 Works well. throttle bore. (cruise , throttle and a/t kick down cables) but the oxygen sensor should sense a rich mixture and reduce the injector on time (pulse width . as a secondary function to adjust the minimum air setting. Check throttle position sensor input voltage. Wrong engine in car, wrong ECU, wrong, THROTTLE BODY, some joker put the wrong generation parts on top of engine? Causing DTC errors like mad. (if not ? when you have it at .50v simply tighten the screws and make sure it stays at .50v some times it will change after you tighten it lower or higher than what you want. Pin 2 is the idle switch. The throttle position sensor (or TPS) monitors the throttle body butterfly valve. The TPS isinfamousto go intermittent first, then fail hard. Seechart on top of this page. (or under of 5v is missing) If youve selected the correct COM Port, youll see data scrolling when the key is in the on position and when the engine is running. BENCH Glitch TESTS? (if 5vdc is wrong, the TPS will not work. Pins C . ---===<<< 2001 Xtreme X-Cab 4.3 W.I.P.>>>===---. The late to open idle switch, will case Tip-in fuel mixing problems. This should force the radiator fans to come on. 1. Adjustment is made by rotating the TPS driver slightly clockwise to increase (counter clockwise to decrease) percentage & voltage. (8v example) listed at the end of this frame. NOT start the engine. Figure 3: Your multimeter should read 0.42 to 0.45 Volts DC with the throttle plate closed. An electronics guy, calls this the wiper pin, that is because it wipes the carbon, as it moves and picks off a new resistance, as it moves. (if the auto ranger shows 2.01 K that means near 2000 ohms, K means times 1000. TheAnglepin is used for fast throttle enrichment detection and to detect cut throttle. Start the engine to test the TBI. If you get this wrong , the engine RPM , may surge & THROTTLE TIP-INacceleration will hesitate ! Open the hood of your car and locate the TBI. Sides: now just put the throttle body back on while being care full not to bump the TPS, put . Anyway, after adjusting the sensor to as close to .45v as poss with the ign on but without the engine running, i done the reset thingy with the on off for 5 secs 5 times and started her up and the light stayed out (for the 1st time in a couplo weeks) for about 5 minutes on idle with a little reving now n then. It senses the air, heat, and light, and sends the information to the ECM which adjusts the throttle and fuel supply accordingly. Make sure that the throttle valve moves during above 10 seconds by confirming the operating sound. Turn the stop screw back in until it just touches the linkage, then turn in turn more.
