DTC P0113: Intake Air Temperature (IAT) Sensor Circuit, High Input: Condition

DTC is set when Engine Control Module (ECM) detects Intake Air Temperature (IAT) sensor voltage is more than 5 volts for 5 seconds continuously (high voltage - high resistance - low intake air temperature). DTC is also set when intake air temperature is low and IAT circuit resistance is high. MIL is illuminated when ECM detects malfunction during first drive cycle. Possible causes are:

• ECM malfunction.
• IAT sensor malfunction.
• IAT sensor circuit malfunction.
