P007C – Charge Air Cooler Temperature Sensor Circuit Low (Bank 1)

P007C – Charge Air Cooler Temperature Sensor Circuit Low (Bank 1)
Description:            The powertrain control module (PCM) continuously monitors the CACT circuit for concerns. The test fails when the temperature is greater than the calibrated value for the sensor or a short to ground is detected in the circuit.
Possible Causes:       
Damaged turbocharger boost pressure (TCBP)/charge air cooler temperature (CACT) sensor
CACT circuit short to ground
VPWR circuit open
Low air flow through the charge air cooler (CAC)
Damaged harness connector
Damaged harness
Diagnostic Aids:
Check the harness for intermittent concerns, incorrect connections, routing, alterations and damage due to contact with other components.
The TCBP/CACT sensor is a dual function pressure and temperature sensor located on the intake air tube between the CAC and the throttle body.
