The engine control module (ECM) checks the signal for the intake air temperature.

The diagnostic trouble code (DTC) is stored if the engine control module (ECM) detects that the signal from the intake air temperature (IAT) sensor is higher than a calculated desired value.

The diagnostic trouble code (DTC) can be diagnosed under specific driving conditions.

Substitute Value

Predefined value for intake air temperature.

Three-way catalytic converter (TWC) preheating and idle air trim diagnostics are disabled.

Possible Source

Contact resistance or oxidation in the intake air temperature (IAT) sensor terminals
Damaged intake air temperature (IAT) sensor.

Fault symptom[s]

Malfunction indicator lamp (MIL) lit
Poor performance.
