Code P112C GMC Description

The Intake Air Temperature (IAT) sensor contains a semiconductor device which changes the resistance based on the temperature (a thermistor). The IAT sensor is located in the air intake passage of the engine air induction system. The IAT sensor has a signal circuit and a ground circuit. The Powertrain Control Module (PCM) monitors the Intake Air Temperature Sensor signal. The PCM sets the OBDII code when the Intake Air Temperature Sensor signal is out of factory specifications.
