Code question
P1111 - Intake air Temp. (IAT) Sensor, Intermittent high voltage
Anybody have a clue what this is? could this cause it not to start?
Thanks!
P1111 = System pass, No PCM system faults detected
These are IAT codes.
P0113 = Intake Air Temperature Sensor Circuit High Input.
P0112 = Intake Air Temperature Sensor Circuit Low Input.
Even if your IAC was bad it would be ignored by the PCM
and assume it's 59F disable exhaust back pressure operation
so it shouldn't affect starting
