Monitor Description
WARNING: This page is about a different variant/trim than selected.
The ECM calculates the internal temperature of the ECM based on the output voltage of the ECM internal temperature sensor. If the output voltage of the ECM internal temperature sensor is not within the normal operating range, the ECM will illuminate the MIL and store a DTC. In this case, the ECM internal temperature sensor may be malfunctioning or there may be an open or short in the sensor circuit.
Example:
When the output voltage of the ECM internal temperature sensor is less than 0.22 V, or higher than 4.91 V for 3 seconds or more, the ECM illuminates the MIL and stores a DTC.
