Set Condition

WARNING: This page is about a different car, the 2025 Jeep Grand Cherokee. 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), Engine Coolant Temperature (ECT), and the Charge Air Cooler (CAC) Temperature Sensor values. If one sensor value is not within 15°C (59°F) of the other temperature sensors, a DTC will set.

NOTE:

The TMAP Sensor is a combination of the CAC Air Temperature Sensor and the TMAP Sensor.
