WARNING: This page is about a different car, the 2016 Jeep Wrangler and 2015 Jeep Wrangler. However, it is still accessible from the selected car via links, so may be relevant.

This diagnostic runs continuously when the following conditions are met:

Engine off time is greater than 480 minutes.
Ambient temperature is greater than -64°C (-83°F).
Vehicle has been driven for one minute over 35 mph.
- Once the vehicle is soaked for a calibrated engine off time and then driven over the calibrated speed and load conditions for a calibrated time, the PCM compares the Ambient, Engine Coolant and Intake Air Temperature Sensor values.
