Circuit/System Description

WARNING: This page is about a different variant/trim than selected.

The charge air cooler (CAC) temperature sensor and intake air temperature (IAT) sensor 3 are variable resistors. The IAT sensor 3 is located in the CAC inlet duct. The Charge Air Cooler Temperature Sensor is located in the CAC outlet duct before the throttle body assembly. The engine control module (ECM) supplies 5 V to the signal circuits and a ground for each sensor's low reference circuit. The ECM monitors the Charge Air Cooler Temperature Sensor and the IAT sensor 3 circuits in order to calculate the temperature of the fuel air. The ECM monitors the CAC sensor and IAT sensor 3 signal for excessively high or low voltages or for a voltage that is not in correlation with the other sensor's start up signal.
