Engine cuts out and does not accelerates


you will have both a throttle position sensor and a peddle position sensor both fitted to your throttle ,the cars ECU must pick up both sensors so it is not doing so you may need to change the throttle body.as you can not just change the sensors on there own.

Codes don't always mean a bad senors. One new TPS sensor would have me moving on to something else. Put a scan tool on it and not just a code reader. Check fuel pressure with the gauge on the windshield as you drive.

On a 04 camry with 2.4 ltr engine, can I replace just the throttle position sensor or do i have to replace the entire throttle body? The engine code said faulty throttle body.


I think the terms "Throttle Positon Sensor", TPS and "Throttle Body" can be misleading at least in regards to the 04 Camry.

My 04 Camry gave a diagnostic reading of P2121 for my problem "Throttle PEDAL position switch D circuit". However, we changed out the complete Throttle Body/TPS (Toyota Part #22030-0H020) that did NOT fix problem.

The 04 Camry TPS Electronic Module "Throttle Positon Sensor" is factory assembled and riveted to the side of the throttle body. The only way to service/inspect it would be to cut off or drill out the rivets. Not sure you could open the darn thing if you got it off, but that seems to be the only way Toyota sells them!!

Hopefully a new Throttle PEDAL Position Sensor (Toyota Part # 78010-33010 PEDAL ASSY, ACC)
will fix it. This is located under the dash near the accelerator pedal.

So, now I would recommend FIRST to replace the "Throttle PEDAL Positon Sensor" (it is much, much cheaper) and then the Throttle Body/TPS assembly!! Unless of course, you get a diagnostic code as you did for "faulty throttle body!!

Chevy Cobalt '06 The vehichle TPS is reading at 36% when the car is off Scan tool commits that the percentage should be at 0% -I have replaced the TPS at gas pedal ..did not solve ..how do I recalibrate...


The TAC (throttle actuator control) is where both TPS sensors reside. On an older system this would be the throttle body. This system uses redundant TPS and APP (accelerator pedal position) sensors. If the problem were with the APP then you should have a code for a correlation problem between the TPS and APP or one APP sensor to the other. The most common issue by far that I have found is carbon build up in the throttle bore causing the plate to be stuck open. Remove the air intake tube from the TAC assembly and see if there is a ring of carbon around the area of the throttle plate. If so then using carb spray and an old toothbrush, clean the throttle body out. You can hold the plate open manually to do this but make certain the key is off or you will set several other codes and the throttle plate will fight against you. You can also remove the TAC assembly to clean if you like, though I do not recommend it. When you are done you will need to start the vehicle and run in drive for a minute or so, then to park or neutral. A couple of these cycles will usually relearn the position of the plate so that you can test drive. (Carb cleaner in the intake manifold will usually make the first start difficult.) Clear the codes, test drive the vehicle normally, but increase the take off and stop hard a few times after a few minutes of easy driving. Check and clear any codes that may have set on the test drive. You will want to drive again normally and check for codes again. If you do not have carbon the most likely culprit will be the TAC itself. The TPS sensors are intergral so you usually need to replace the whole TAC. Though I have seen only a handful of them that actually need replacement.
Good luck

Throttle/Pedal Position Sensor/Switch B Circuit Range Performance


there is no adjustment on these tps's it's a drive by wire system. If you don't know the vehicle, dont post!
there's 2 sensors contained in the pedal sensor, and one on the throttle plate shaft, more often than not, it's the pedal sensor, and if you replaced that, it's the other one or a loose connection. did you reset the computer after replacing the pedal?

Hi

It sounds like the (TPS) is bad on it it will cause this problem but it should show a trouble code . The (TPS) is on the throttle body this is what it sounds like to me.

I would start with the TPS, and if it doesn't solve it then the AFM would be the problem.
