I set the bore/TV gap (if monkeyed)(see my crude solutions here) slack 10mm (7/16 inch) ( Up to 3 cables on A/T cars and cruise opted engines. The TPS switch, must open at the correct moment or the ECU will be very confused ! The POT side TP SIDE: The ECU sees VOLTS on this pin, and watches forfast changes to the voltageand never (cept cranking) uses the exact voltage to do anything. Heres this same car with the engine running and idling at 900 RPM. (ECU sees, idle switch closed and RPM is a 4000 RPM, and low plenum vacuum..oops.?). The below graphic is for the OHMS test, but in fact this same drawing showsyou, what pins to test for the live voltage tests. The ISC will be dead ! BENCH Glitch TESTS? keep your foot off of the pedal You want the TPS reading in both the Dash & Sensor Display to be as close to zero as possible (-0.3 in this example). If you also look carefully the TV throttle stop screw isblocked from anyone touching it !!! You control the throttle body position with the . (using 20k meter range) never reads infinity. (use a 6v, 9v or 12vdc battery as your supply , or a 5v power supply , really 3 to 12vdc works. ) Myth 1: No, the TP side does not set fuel injection rates, that is, the ohms (voltage) does not get scaled directly to injection quantity. To see more facts andtheories. steady it must be. With the ignition still on, Adjustment is made by rotating the TPS driver slightly clockwise to increase voltage. NOT start the engine. unbolt that nut below (stud) and remove the DP for calibration. (put the. If the TPS errors are bad enough (with DTCs to match) and constant, the ECU may go, tolimphomemode and car does start. As the throttle opens it will turn the shaft counter clock wise looking at it from passenger side of the truck. The code that showed up was P2135 which indicates a throttle issue. (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. The G16a/b TPS, has 2 parts, It is Ganged ! Install the air cleaner duct and tighten with the Phillips screwdriver. 1991+, Graphic 1: You can do on car voltage tests, or simple ohms (resistance )test. ON means the switch is closed (very low ohms ,Typical. If not unplug it and check it with the TB closed. The TPS is the key sensor (instigator) to Enrich mode, that ends STOICH air/fuel/ratio , entering Enrich mode,as seen here. DTC 44 , and 45 ( 45 is stuck at ground , very rare this , is a harness short) 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. On cars that dont have an adjustable throttle position sensor, the ECM repeat them all. 6. 13.01 Buy It Now (hesitations). Gray/red Seeing this aberrant glitch with some DMM can be very hard, as they are so slow to measure, and can miss the glitch. The TPS was calibrated using the wrong feeler gauges, as seen on many store, rag books or on line. The idle switch must be closed and near 0v running or the timing freezeor EGR, ISC will fail to work and DTC 44s happen. Set the scan tool to TPS voltage (or connect DVM) then set the adjustment screw for the lowest value & still touching the throttle arm stop. (aka SPI ,er, single point injected, bla bla) (or have dead spots as you turn the throttle shaft). ), blocked from anyone touching it !!! discovered most shops dont have these tools anymore. Turn the ignition off. How do you adjust the volts for the tps? THE REAL DEAL ! Remove the TBI using an Allen wrench. (or under of 5v is missing) If your meter is a fixed range meter not auto ranging then ,use the 2000 or 2k ohm range. The sensors all eventually wear out and the throttle angle pins starts glitching or has dead spots. See hopeless. The FSM instructions, are are linked in every section on calibation and does cover this step. SPI Single point injection, by some. It allows air to bypass the throttle plate. The Advance must be smooth. (even glowing cherry red) The PCM on that truck will look for a TPS input signal to help determine the shift points and main line pressure of the 4L60E. Removing Your Sensor Follow these steps to replacing your sensor. so the engine idle speed obtains 550rpm in drive (auto trans) or 650rpm in This may be .045-.065 volts. at throttle tip-in (evil effects here). If the TPS goes bad it can make the machine run erratically, or cause a hesitation at certain rpm's. Only the Dashpot on top left of TB throttle body, is allowed to do this. the Throttle Position Sensor, which we discussed in my Jan/Feb 2008 segment. Not my write up,but found this on anothere forum : most of the 80's model GM TPS sensors were adjustable. internal loads/friction which can also result in a drop of idle vacuum levels. I then drop the DASH pot, arm and the throttle opens and the PIN C goes to near 5 volts, (closed switch ) FYI: Push the multimeter pin into the TPS screw and check the voltage. and Setup 1: If your Ford Ranger has a bad throttle body, it can cause it to run terribly. or potentiometer, or variable resistor. SFYAUTO CPS Crankshaft Position Sensor 12596851 5S1695 Compatible With GMC Pickup Chevy Silverado Suburban C1500 K1500 K2500 K3500 G30 P30 Cadillac . the K shows up on the LCD display , or omega sign or M for million. (all years 8v) (this procedureassumestheTPS is not badand that it was installed correctly , Indexed ) SEE16V Calib. STOICH: (means perfect fueling) that happens in Closed Loop mode of the ECU. TB =Throttle Body. The readings should be the same as seen above in the WinALDL testing method. provided earlier. (using just a cheap SMOKE detector battery) (gotsymptoms?) neutral (manual trans). First, find the sensor. TV= throttle valve, that is the butterfly valve, dead center inside theTB,the Throttle body. Doing the calibration is bestdone on th work bench. If you have a scan tool, I recommend allowing the engine to warm up to Tighten the screw by turning it clockwise. One little secret that helps understand the TP pin (throttle angle) is that the ECU TP pin has a 470k ohm pull down resistor inside ECU so that if the TP pin goes open the ECU sees 0 volts (for safety) If the throttle position sensor fails, your ECU doesn't know how much air is passing through the valve. You control the throttle body position with the . TESTING the 16V TPS. use tie wraps or bailing wire to tie it back some way. Location. Any time the IAC valve is replaced, this learn procedure should be about 50 ohms or near 0volts) OFF means the switch reads, Infinity. can cause a code to set. (if the auto ranger shows 2.01 K that means near 2000 ohms, K means times 1000. (This cut wire,etc) TCM, transmission controller module (4 speed automatic) (tie it back, to do the Calibration works) throttle bore. Replace the TBI by placing it back in the engine. (on say a Toyota ,we set it to 0 ohms), (I then look down the Throttle air horn and be sure the brass yellow TV valve is 100% closed, if not?, all this is hopeless. Dashpotmust be retractedby hand, during tests, any of 3 ways. AKA: throttle angle tests (TBI G16A example) TheAnglepin only needs to be linear, (foot action to Ohms(volts) It mustnot glitchas you drive. The TPS, is dead because you have a A/T to M/T swaps or the reverse and done wrong, wired wrong or the wrong ECU used, for each. (Throttle Position Sensor, Switch) See above graphic 1, for pin assignments. The engine is.030 over with a EFI cam and 9.5:1 compression with aluminum 63cc heads. If you removed the TPS and didnt index the body TPS pins to the TPS actual pin sockets, none of this will work correctly. I check that C to D is equal to or below 300 ohms throttle closed (if not it needs calibration) (G16A TBIDash potIS FULLY retracted) if infinity its out of calibration, if 300 or below its OK. Or bad luck, fate, or ? TheAnglepin is used for fast throttle enrichment detection and to detect cut throttle. Figure 3: (warning the TPS actual wire colors can vary, but not the car harness colors that dont. The TPS should read between 4.0 and 5.5 volts. Off car, you see the plate is not closed or is full of gunk blocking it open. (varies by maker of DMM) The TPS can fail this way: the TPS is out of adjustment or the sensor has failed. In 1991 GM changed the throttle position sensor connector and there are two styles of EGR solenoid . Connect the voltmeter red lead to this pin and place the black lead on a good engine ground. Vehicles Motors Vehicles use the Vehicles in the same manner as most automobiles. Disconnect the negative battery cable and set it aside. on TPS look here. The 1996 to 1998 real FSM calibration procedures for TPS is Here and Here. Turn ignition switch is "ON". Attach an Ohm meter (DVM set to ohms resistance starting on the 2k range 2000 ohms) per instructions. The dash pot is the cold start, fast idle device, (short duration 3 to 30 seconds (30 is in Alaska). (all ways) Never adjust the painted or capped off,throttle stop screw, for any reason. Keyon, NOT RUNNING test: The next steps are an audit of your work. M/T = Manual transmission, A/T , yes, automatic (this is all ASE /SAE jargon. When working correctly it used to read 0.65v at idle and the "new" one which replaced it reads about 0.56-0.58. on the IAC pintle, or in the idle air passage restricting air flow, There is carbon buildup Pin B, voltage must move, and bedirectly proportionalto your throttle actions ! If may steps below are not clear enough then the Actual real SUZUKI FSM is here. Consult the engine diagram that came with your vehicle for extra guidance. Standard Ignition 3 Terminal Connector - S674. NORMAL. If the engine doesn't have enough air, the air-to-fuel mixture ratio is off, and some fuel might be left after the spark. Anything over 4.5v is what the computer sees as full throttle. 180F+ coolant temperatures. FYI: Turn the engine on and let it warm up for about five minutes. Test 3: Pin B is throttle angle, or a.k.a. (by people) Open the hood of your car and locate the TBI. Pre-conditionals: Easy to install to replace 20 year old components. Your Equinox's throttle body controls the amount of air that enters the engine. special tools available that are designed to test GM IAC valves, but I have Part 1 of 2: Removing the throttle position sensor. However, it serves Meter to A and B, the same as above but in reverse actions. (however an analog meter may see them or a graphic GMM may, and all scope for sure can). Then rotate the TPS CCW, then rotate CW it until the TPS (pin1 and 2 )just barely(at the threshold) go toInfinityon, Remove Feeler gage, note the Ohm meter (Resistance meter) shows continuity (less than 300ohms) (ECU expects less than 500 ) (do not expect zero ohms! (except 89/90 years) It may accelerate smoothly, but lack power. side called by Suzuki TP pin, is theThrottle anglepin, and allows for the ECU to enrich fuel with a fast right foot. Any one of the above issues can cause a an IAC fault code to set in the ECM. ignition in the off position, replace the fuel pump fuse. By the way, if idle speed is out of control ?,with the switch closed (0-volts) is coveredfound here. Move the safety pin and positive wire to the 3F connector and repeat the process, checking the increase in voltage. electrical testing means. connected, ground the diagnostic (ALDL) terminal (same as you would do to flash amount of vacuum an engine can generate at idle. And very accurate, even i dont know english very well. The TPS is indexed correctly , that is, inside below the TPS are index pins they must be aligned, and for sure not jamming the throttle open. I am not a body man. The TP pin, A.K.A. When the throttle is fully open, the TPS sends a signal to the car computer that controls fuel injection. In side the TB , Throttle body is a Throttle Valve, TV. Never expect zero when closed ,like most switches. aka, set at threshold of closure. Turn ignition switch is "OFF' wait at least 10 seconds. this gap and that is what I use for guide lines getting this correct. (and many other functions related to this pin) It doesnt have to be accurate , just consistent and linear. The 3 video tests (mp4) TBI Adapters; Throttle Position Sensor; . ! ALive on car TPS voltage test: TBI only. It will never read 0 ohms. DC voltage is measured between pins Sensor (+) and Ground (-). (a fool proof calibration) All pins names and locations are seen inFigure 1 above. This is what needs to be turned to adjust minimum air, or more commonly known as "idle speed". TEST 1: Checking The Throttle Position Sensor (TPS) Signal. It can also be used with the car's ignition turned on but the car NOT running to check other data relative to the TPS. The on car live, key on,voltage testis here. The IAC valve cannot be tested using conventional The throttle body injector Vehicles of a Vehicles helps control the throttle and maintain the Vehicles revolutions per minute, or rpm. (The Throttleanglepin, allows fast acceleration rich mode power enhancement and causes WOT (wide open throttle mode) and causes Unflood mode at crank time. PinB(TP pin) below, the voltage will very, for near 0v to near 5v, as the throttle is advanced. as a secondary function to adjust the minimum air setting. The throttle position sensor (TPS) circuits (wires) that we're gonna' be testing are: Throttle position sensor (TPS) circuit A: GRY (gray) wire and it connects to the F-14 terminal of the blue PCM connector. Do not over tighten the driver like a nut as there are few threads on the throttle shaft and it can be stripped. 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. AHof13. Adjust the TPS to 0.5v that is 1/2 volt, exactly. Put the scope probe to pin B and D. Scope shield ground clip to D If it does not vary in this range or has glitches or has dead spots, it is bad. Wrong engine in car, wrong ECU, wrong, THROTTLE BODY, some joker put the wrong generation parts on top of engine? Once youve downloaded and installed the program, configure it per the directions below. electrical testing means. Unplug the connector from the throttle position sensor. ,due to, toolateIDLE drop out or tooearlyidle release,. ( except some 1.3L Carb. Resetting the throttle body on a Honda is very simple. Not properly indexing the TV shaft pins to the TPS can cause TPS to stick throttle open. installed the TPS following the directions posted elsewhere on the site. Key ON. problem with the engine resulting in lower than expected vacuum levels at idle VOLTS TESTING: using any needle or back probe meter lead set. Such as Subaru or Grand Vitara? One guy mis-indexed the TPS prongs to the matching prongs in the TB, and he got Unflood mode. CALIBRATION GAUGES : 10 years of methods and values. Example, If ordering a TBI kit, or one of the components such as TBI adapters (pic of carbs), Throttle Sensor Kit (pic of carbs), Lucas Distributor Conversion (Distributor pic). You need to back off the setscrew in the driver 1/2 of a turn to set the voltage properly. Common symptoms of a bad throttle body include, dirt and grime, the check engine light, and an erratic idle. Never hot wire any output pins on any ECU. This will take a while to do since the sensor is very hard to adjust due to its sensitivity. (ground) The IAC works by bypassing the closed throttle plate, the valve allows air to circulate inside the car's combustion area and allows the vehicle to idle smoothly. New wiring harness extension assembly to extend the throttle position sensor wiring for the listed applications. (will not attain 500 ohms or less) (if 8v DP retracted) (even fails in hand removed? Threshold is setting it, just so the switch has just closed. Then the ECU causes a hesitation when you demand power. Hopeless:(and solutions) applies to all 1991 to 1998 G16s. Most TPS devices last for 150k miles or more lots more and are very expensive to buy so the testing is well paid for if it passes, tests. Gray/ yellow 0 Volts. is adjusted incorrectly (throttle being held open too far; more on this later), There is a problem with I cannot weld. (example of throttle angle testing and finding dead spots or glitches) MPI is 16v Multipoint Injection motors, and has no Dash pot steps, or device. Do not disconnect the connector, until you wish to do an OHMS test, above. CAL = Only the IDLE switch side is calibrated ! Put back the Dash pot, as you found it. Loosen the throttle position sensor retaining screw with a Phillips-head screwdriver. maintain a set idle speed. rebuilt throttle body spark plugs, wires, cap, rotor, blah blah blah new O2 sensor new TPS sensor cleaned EGR valve and solenoid I can't seem to get the TPS adjusted correctly. Too late TPS idle switch opening. whats wrong with it? Tips for adding power to a throttle body injected (TBI) Chevy 305, 350, or 454 V-8 engine. 1 Throttle Angle Pot. (blocking it open). Loosen the 2- bolts that hold the TPS. A Missing Dashpot on G16a engine. The 4l60e will not respond to manual shifting like the old non electronic . The TPS is now calibrated and validated. following steps. How to time the distributor G16B (16V)? It comes from the factory with a protective metal cap over it. I have the only list like this in the web. Most screws have a T25 torx head, but they also can be an allen PHOTO 3: 92-98 look same. (tie it back, suck it back or remove it.) This mode of running is very rich fueling (and very crude) and the CAT converter will overheat. What is it? (on autoranging meters, it will tell you the scale its on just ofter the readings eg 3.5 k, means 3500 ohms the K ICON on the meter LCD means , times 1000) As noted above, Do not over tighten the driver nut. 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. Measure output voltage of Throttle Sensor using voltmeter. 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. The TPS was calibrated with the DP active. Great for testing all sensors on the car. 2) At idle, its .54 volts, which i think is correct. The throttle position sensor is located on the throttle body. what do you mean? f due to fuel cut at cranking time. loosened the mounting screws unintentionally -- it happens) then minimum air should be adjusted. All pins on allMPI TPS look like this and rules and wire colors ! Make sure your DMM meter is working ok , first. connected, ground the diagnostic (ALDL) terminal (same as you would do to flash : All Rights Reserved. The sensor detects the opening and closing of the throttle valve and feeds that info to the vehicle's computer. 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) This page covers calibration or testing the TPS. W.O.T= Wide Open Throttle. The minimum air setting is what is used to describe the amount of air TBI idle switch test, live ! It can also be used with the cars ignition turned on but the car NOT running to check other data relative to the TPS. rebuilt or cleaned) or the TPS (throttle position sensor) has been replaced or otherwise disturbed (i.e. If the throttle body has been removed (i.e. Make sure that the throttle valve moves during above 10 seconds by confirming the operating sound. One example of this is when the engine is modified, or a different Adjust the TBI. I do not have a ton a high quality tools. prevent the throttle blade from closing too far and getting wedged/stuck in the This method guarantees some tiny fractions of inches ( of over/under-travel.) Loosen TPS side screws, so they are only slightly tight. (the reading of 4.0K is 4000 ohms.) automatically learns the closed throttle voltage when the ignition is keyed on Start engine and warm up sufficiently. Pin 2 is the idle switch.
