throttle position sensor


Recommended Posts

Hy guys, I have scanned my car with ELM and the absolute throttle position sensor when the engine idles is at 16.7 %, is this the correct value or should be 0 % ?


No, that's correct. I think mine is 18% at idle and foot on the floor is 85%. 0% and 100% are the theoretical limits of the system. The ECU takes the lowest reading it has seen and subtracts it from the current reading, so as far as the ECU in your car is concerned 16.7% is zero throttle opening.
