My friend and I just completed a LS (99) swap on a 96 Hatch. After numerous codes and timing problems, now we are at no timing problem, but still have 1 code: P1508 = IAC. We tried switching the wires and no love. We had already changed the wire at the ECU (A14 to A12). The only other thing that could be wrong/bad in the sensor itself. If anyone has any ideas or can shed some light on this matter, it will be really appreciated. Thanks in advance!

 

Morning bump. Anybody?!?!

 

Did you cut off the original 3-pin connector and solder on the LS 2-pin connector?

Like EE_Chris said, just make sure you cut the orange wire and moved the one in pin A14 to A12. Otherwise, I'm thinking your sensor might be bad.

 

e-kay and EE_Chris;
I did use the 2-pin connector from the LS and also taped away the orange wire. The A14 to A12 wire move was done (looking at the A-plug from the wire-to-plug side). Now I'm getting the following codes: IAC (solid code) and EVAP (pending code). We also tried switching the wires to the IAC plug, but no love. We think that we might have crossed the yellow-black wire on the EVAP and IAC plugs. They both have a yellow-black wire. Any more info would be appreciated. Thanks!
