Set Condition

WARNING: This page is about a different car, the 2024 Jeep Grand Cherokee L. However, it is still accessible from the selected car via links, so may be relevant.

After a calibrated amount of cool down time, the Powertrain Control Module (PCM) compares the Ambient Air Temperature (AAT) Sensor, Engine Coolant Temperature (ECT), and Intake Air Temperature (IAT) Sensor values. If the general temperature rationality passes, the PCM compares the Engine Oil Temperature (EOT) Sensor value to a threshold based on the other temperature sensor values. If the difference is greater than a calibrated value, the diagnostic fails.
