I have a 99 F150. I just had to replace my ac clutch and after doing that my CEL light came on. I was told it was p 113 (the IAT Sensor). Can anyone give my some help on fixing this problem or what needs to be done to get the light off.

 

You might have bumped it while working on the AC. It's connected to the air intake right after the MAF sensor. Make sure the electrical connector is plugged in and not damaged
P0113 - Intake Air Temperature (IAT) Circuit High Input
Indicates the sensor signal is greater than Self-Test maximum. The IAT sensor maximum is 4.6 volts or -50°C (-58°F).
Open circuit in harness
Sensor signal short to power
Damaged sensor
Improper harness connection
Damaged PCM

Good Luck!
