Can anyone tell me what healthy supply voltages are for the 6 pins on the accelerator pedal position sensor? Looking into the plug on the sensor, with the two locator horns facing up, my car is supplying, left to right: 2.2v, Ground, 2.2v, Ground, 5V, 0V (not grounded) With sensors unplugged, ecu reads 2.2v on both, so I'm thinking those 2.2v pins are the output pins, the 2.2v is just from a pull up resistor, and that 0V should be 5V. I should add, with sensor plugged in, sensor 1 reads 0.8v up to about 3.8v, sensor 2 reads 0.01v-0.02v Link to comment Share on other sites More sharing options...

And it all works again! Now I've just gotta book in a fun weekend sometime pulling trim, breaking clips and trying to trace where the loom break is. Pic of potentiometer board for anyone who might be interested. And I think the numbers I've used are the reverse of what's labelled on the outside of the sensor. 1 Link to comment Share on other sites More sharing options...
