Set Condition

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 MAP Sensor is a combination of the CAC Air Temperature Sensor and the MAP Sensor.
