DTC P0111: Intake Air Temperature Circuit Range/Performance Problem: Condition

DTC is set when variation in intake air temperature is less than predetermined after engine is at operating temperature. This is a continuous monitor. MIL is illuminated when Powertrain Control Module (PCM) detects malfunction during 2 consecutive drive cycles. Possible causes are:

• High circuit resistance.
• Intake Air Temperature (IAT) sensor malfunction.
• PCM malfunction.
