Hey all, I'm looking for an ECU diagram for a P28 with all the pins and labels for what they do. I'm specifically trying to figure out which 2 terminals i should test for voltage across to see if its right. I'm getting a code 14, IACV, and i wanna see if its the ECU, or my wiring harness.

There is NOTHING wrong with the IACV, i run my P2P on it all day long.

help meeee!
