|P007B – Charge Air Cooler Temperature Sensor Circuit Range/Performance (Bank 1)|
|Description: The powertrain control module (PCM) continuously monitors this sensor for concerns.
This DTC sets when the charge air cooler temperature (CAC_T) parameter identification (PID) does not correlate with the intake air temperature (IAT) or the intake air temperature 2 (IAT2) PIDs at ignition ON. It will also set if the IAT PID reading is greater than a maximum calibrated value while driving.
Possible Causes: • Damaged turbocharger boost pressure (TCBP)/charge air cooler temperature (CACT) sensor
• Contaminated or blocked TCBP/CACT sensor
• Slow responding TCBP/CACT sensor
Diagnostic Aids: Check temperature values while engine is at ambient temperature, cold soak the engine for a minimum of 6 hours if necessary.
Check air flow through charge air cooler (CAC), remove debris if necessary.
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.
