Set Condition

WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

Ambient Air Temperature (AAT), Engine Coolant Temperature (ECT), and Intake Air Temperature (IAT) Sensor values are compared during a cold start.
After start up, the values are monitored. If one of the readings is not plausible for two consecutive trips, a DTC is stored.
