DTC P111C-62: Control Module Internal Temperature Sensor/Intake Air Temperature Sensor Signal Compare Failure [11/2023 - ]: Description
WARNING: This page is about a different variant/trim than selected.
The engine has an ECM internal temperature sensor and intake air temperature sensor.
The resistance of a thermistor within the ECM internal temperature sensor and intake air temperature sensor increases as the temperature decreases and decreases as the temperature increases.
The voltage monitored by the ECM changes in accordance with the change in the resistance of the thermistor.
The ECM performs control based on these voltages.

HINT:
- Waiting is required to prevent the temperature of the engine from affecting the readings. If the engine has been operated recently, it is not possible to accurately compare the readings.
- For diagnosis, in order to duplicate the detection conditions of the DTC, it is necessary to park the vehicle for 7 hours. Parking the vehicle for 7 hours ensures that the actual temperature of the ECM internal temperature and intake air temperature (for mass airflow meter sub-assembly) are very similar. When the vehicle has been parked for less than 7 hours, differences in the readings may exist, but this does not necessarily indicate a fault.
