I started my car today to go to school it was about 34 dgrees out side and i let my car warm up then i started driving and my check engine light turned on then a mile down the road it turned off...i took it to autozone and they said it is code #114 ..they said it is the air charge temperature circuit (ACT) and then i looked on midwestsho.com they said it is the IAT sensor out of range dose anybody have any idea what this is ?
