DTC P06AB-11: Control Module Internal Temperature Sensor "B" Circuit Short to Ground; DTC P06AB-15: Control Module Internal Temperature Sensor "B" Circuit Short to Battery or Open [10/2022 - 11/2023]: Description

WARNING: This page is about a different variant/trim than selected.

The ECM has a built-in internal temperature sensor which detects the internal temperature of the ECM. The resistance of the thermistor within the ECM internal temperature sensor changes according to the internal temperature of the ECM. The resistance of the thermistor increases as the ECM internal temperature decreases and decreases as the ECM internal temperature increases.
