sensors?

[antbella]

help please what is a pedal position senor?

[SleepyHead98]

sounds like a brake related sensor, that senses if the brakes are being pressed by the driver or not/ which will cause the brake lights to come on in the back when the peddle is pressed.

How about what year this is, there is no pedal position sensor other than the throttle position sensor , post back when you have the proper terminology of what you are looking for.

APS, or accelerator pedal sensor, is used in electronic throttle systems(also known as drive by wire throttle systems), in other words, systems that don't use a cable between the pedal and the throttle body....in GM cars, this is known as TAC, or throttle actuator control....the APS sends a signal to the PCM and the TAC module, which electrically controls a motor on the throttle plate......so the throttle plate is electrically moved, rather than by a cable from the accelerator pedal....

I'm sure everyone remembers the massive recall that Toyota had on their gas pedals, which included GM's Pontiac Vibe, a joint venture with Toyota....

Correct on the pedal sensor /drive by wire, correct me if I am wrong here but I do not believe at the end of the Park Ave run these were implemented and it was still a cable connection throttle.

I was only answering his question, Max....

As for whether this system was used on the last PA's, I'm not sure....

Yeh, lots of guesswork as usual on our part with insufficient info from the OP's.
