Set Condition
WARNING: This page is about a different car, the 2014 Dodge Journey. 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 AAT, ECT and 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 temp sensor values. If the difference is greater than a calibrated value, the diagnostic fails.
