HELP - Voltage check on AFM 4th wire
Can anyone tell me roughly what the 4th wire on the pre face lift afm should have as a voltage.
It doesn't say in the manual, and it goes to pin 37 on the ecu.
I know it is a potentiometer to adjust AFR's but mine has previously been fiddled with, and I am trying to figure out what it should be.

Ok. Just in case anyone else is searching. The replacement that arrived today reads 0.346 M Ohms and 5.1v.
The one on my car when set to 0.346 M Ohms reads 3v.
I'll update when I swap them over and test drive. Hoping it will sort my hesitation.
