Owen Posted March 8, 2002 Share Posted March 8, 2002 I have a TPS and an IAC from a 1994-1996 Vette and am trying to determine what pins are used for what wires (pin A=5v, B=12v, C=GND etc.) The local service departments at the dealers are morons and are ignoring me. Anyone have a shop manual or know someone they could ask? I have a copy of the manual but the stupid thing doesn't say which way is up and the sensor is marked with pin letters! Help! TPS 17106680 IAC 17113099 Owen Quote Link to comment Share on other sites More sharing options...
Guest greimann Posted March 8, 2002 Share Posted March 8, 2002 I have a Camaro book and it says that the TPS Pin A = 5 V Return (I assume that to mean negative) - Black Pin B = TPS signal - Dark blue Pin C - + 5 V ref - gray I would think that most GM TPS's are the same.

Owen Posted March 8, 2002 Author Share Posted March 8, 2002 Thanks! Man that Delillo on Beach Blvd...no professionalism. Never saw the GND labeled as 5V return though. Do you have anything for the IAC? And what year Camaro is this coming from? Thanks, Owen Quote Link to comment Share on other sites More sharing options...
Guest greimann Posted March 8, 2002 Share Posted March 8, 2002 Ok I found the IAC. It is a little more cryptic. BTW it is a '92 Camaro Haynes manual. Pin A = IAC coil "A" Hi - lt blue / white Pin B = IAC coil "A" Lo - Lt blue / black Pin C = IAC coil "B" Hi - Lt green / white Pin D = ICA coil "B" Lo - Lt green / black Quote Link to comment Share on other sites More sharing options...
