DTC 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: |
|
||
| Diagnostic Aids: | Check temperature values while engine is at ambient temperature, cold soak the engine for a minimum of 6 hours if necessary. Check airflow 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. |
