Monitored & Set Conditions

Engine Coolant Temperature (ECT) sensor voltage is monitored when engine off time is greater than 480 minutes and ambient temperature is greater than 39°F (4°C). After a calibrated amount of cool down time, the PCM compares the ECT Sensor, IAT Sensor and the Ambient Air Temperature Sensor values. DTC will set if the ECT Sensor value is not within 18°F of the other 2 temperature sensors. DTC is a two trip fault.
