just wondered why this sensor seem to cause probs far end of travel, you wouldnt think it would wear out as you dont spend all the day with your foot flat down.

why dont it cause probs in the upper and middle area of travel where most driving is done ?

has anyone opened one and tried to clean it up and make it work right again

reading thru the threads nearly all the problems are related to when the pedal is floored . i dont knbow just wondered as it cost

Sorry, but I'm typing slowly, as my left hand is all bandaged <_< ....in some VAG engines the sensor is a potentiometer with a set of contacts at one end of the travel. Which engine code is yours, and I can check?

 

If yours is like the others I have seen, the outputs are closed/open and variable resistance according to throttle position.

 

My experience of these is....

 

1. Worn out track/pick-up, so variable output signal goes open circuit.

2. Broken or shorted contacts.

3. Water ingress (due to power washing the engine bay).

 

I've never opened one up.
