|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.
