DTC P0112: Intake Air Temperature Sensor Circuit - Low Input: Condition

DTC is set when Engine Control Module (ECM) detects Intake Air Temperature (IAT) sensor voltage is lower than 0.16 volts for 5 seconds continuously (low voltage - low resistance - high intake air temperature). MIL is illuminated when ECM detects malfunction during first drive cycle. Possible causes are:

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