My check engine light came on after I installed a CAI. The code is for the air temp. sensor. I replaced the sensor, and the pig tail clip for it. The light stayed on. I put the stock air box back on to get the light off for state inspection, but light came on shortly after. I now have the CAI back on and what do you know the light is back on. The only thing I can think of is the CAI comes off the MAF. I wanted to save money and did not buy the whole kit with the piece from the throttle body to the MAF. Did not think it would make a difference. Any suggestions on how to get the light off?
