DTC: P0112

Search Bulletins/Recalls for P0112

Trouble diagnosis name: Intake air temperature (IAT) sensor circuit low input

Component Description

The intake air temperature sensor is built into mass air flow sensor. The sensor detects intake air temperature and transmits a signal to the ECM.

The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in response to the temperature rise.

DTC detecting condition:

• An excessively low voltage from the sensor is sent to ECM.

Possible cause:

• Harness or connectors (The sensor circuit is open or shorted.)

• Intake air temperature sensor may be faulty.
