WARNING: This page is about a different variant/trim than selected.
DTC DESCRIPTION P007B - CHARGE AIR COOLER TEMPERATURE SENSOR CIRCUIT RANGE/PERFORMANCE (BANK 1)
| Description: | This DTC sets when the charge air cooler temperature (CACT) sensor value does not correlate with the intake air temperature (IAT) sensor value or the intake air temperature 2 (IAT2) sensor value at ignition ON after a calibrated soak period (typically 6 to 8 hours). If the IAT2 sensor is not present, the engine coolant temperature (ECT) sensor value or the cylinder head temperature (CHT) sensor value is used for the rationality test. This DTC also sets if the CACT sensor value exceeds the maximum calibrated temperature threshold 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. This DTC may be accompanied by other DTCs. Check for other DTCs and diagnose those first. |
