Set Condition

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.

Once the vehicle is soaked for a calibrated engine off time and then driven over calibrated speed and load conditions for a calibrated time, the PCM compares the ambient air, engine coolant and intake air temperature sensor values. If the values of all the three sensors are more than 15°C apart, the general temperature sensor rationality test fails.
