Pinouts for FG accelerator pedal position sensors

[TurboBurbo]

Hello.

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

After pulling the circuit board out and giving it a look, I decided pin 6 was highly likely to require 5V...so *Autosparky Puritans Look Away Now* I decided to pull out pin 6 and bridge 5V supply pin 5 across to it. 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.

Nice work to sort it out yourself
