QuestionMy AIT sensor is incorporated in my MAF. i was wondering if anyone knew the wiring color code for that so i could find the two IAT sensor wires from the rest of the wires in this harness.
AnswerSorry for taking so long, Billy. Normally, I look these things up at www.hmaservice.com, but I'm not at work and the computer I'm using isn't running Internet Explorer. If you'd like to view the schematics of your car, you can (providing you have Internet Explorer) go to www.hmaservice.com and register for a free account. You'll also need Adobe SVG Viewer (free download) to view the schematics.
Here's what I found at ALLDATA, though. The air intake temperature sensor is separate from the air flow sensor and should be in the back of the intake manifold. Here are the wire colors for each:
Air flow sensor:
Pin 1: Black/white -- ground through ECM
Pin 2: Blue/white -- air flow signal
Pin 3: Orange -- 12V sensor power
Air intake temperature sensor:
Pin 1: Green/black -- sensor signal
Pin 2: Black/white -- ground through ECM
I recall telling various people (although I'm not sure which cars and engines) that their air flow sensor was part of the MAF based on information at www.hmaservice.com. If what I've listed here isn't consistent with your car, I'll try to get to a computer that has IE and check the www.hmaservice.com website as well. Unfortunately, I'm off work this week, so I don't have all the resources at my disposal that I normally have.
