My check engine light keeps coming on periodically while driving so I had my friend read the codes the other night. He performed the test where you start the car and plug it in. He got a 74 and 77, but I read somewhere to ignore those. Today while I was getting my steering rack installed I had my mechanic drive it and run a test and he ended up getting this:
54 Intake Air Temperature (IAT) or Vane Air Temperature (VAT) signal high - IAT VAT
So I guess my question is, what could this be and how do I go about fixing it?
P.S. - on an interesting sidenote, my ARC's had stopped working while I had no working p/s (firm mode would only work for half a second) and now they're back to normal as soon as I got the new rack.
