DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
PCM P007A:00 Charge Air Cooler Temperature Sensor Circuit (Bank 1): No Sub Type Information This DTC sets when the charge air cooler temperature (CACT) sensor value is not within the expected range.
PCM P007B:00 Charge Air Cooler Temperature Sensor Circuit Range/Performance (Bank 1): No Sub Type Information Sets when the PCM detects the CAC temperature sensor value does not correlate with the IAT sensor value or the IAT2 sensor value at ignition ON after a calibrated soak period (typically 6 to 8 hours). This DTC also sets if the CAC temperature sensor value exceeds the maximum calibrated temperature threshold while driving. Check temperature values while engine is at ambient temperature, cold soak the engine for a minimum of 6 hours if necessary. Check airflow through CAC , remove debris if necessary. This DTC may be accompanied by other Diagnostic Trouble Codes (DTCs). Check for other Diagnostic Trouble Codes (DTCs) and diagnose those first.
PCM P007C:00 Charge Air Cooler Temperature Sensor Circuit Low (Bank 1): No Sub Type Information Sets when the PCM detects the CAC temperature is greater than a calibrated value or a short to ground is detected in the CAC temperature circuit. This DTC may be accompanied by other Diagnostic Trouble Codes (DTCs). Check for other Diagnostic Trouble Codes (DTCs) and diagnose those first.
PCM P007D:00 Charge Air Cooler Temperature Sensor Circuit High (Bank 1): No Sub Type Information Sets when the PCM detects the CAC temperature is lower than a calibrated value or an open or short to voltage is detected in the CAC temperature circuit. This DTC may be accompanied by other Diagnostic Trouble Codes (DTCs). Check for other Diagnostic Trouble Codes (DTCs) and diagnose those first.
PCM P0096:00 Intake Air Temperature Sensor 2 Circuit Range/Performance (Bank 1): No Sub Type Information Sets when the PCM detects the IAT2 sensor value does not correlate with the CAC temperature sensor value or the IAT sensor value at ignition ON after a calibrated soak period (typically 6 to 8 hours). This DTC also sets if the IAT2 sensor value exceeds the maximum calibrated temperature threshold while driving. Aftermarket heaters that are attached to the engine, transmission or battery may cause DTC P0096 to set in cold weather climates after a 6 hour soak period. This DTC may be accompanied by other Diagnostic Trouble Codes (DTCs). Check for other Diagnostic Trouble Codes (DTCs) and diagnose those first.
PCM P0097:00 Intake Air Temperature Sensor 2 Circuit Low (Bank 1): No Sub Type Information Sets when the PCM detects the IAT2 sensor signal is less than the self-test minimum. The IAT2 sensor minimum is 0.2 volt. Monitor the IAT2 PID value. A typical IAT2 sensor temperature should be greater than the IAT sensor temperature.
PCM P0098:00 Intake Air Temperature Sensor 2 Circuit High (Bank 1): No Sub Type Information Sets when the PCM detects the IAT2 sensor signal is greater than the self-test maximum. The IAT2 sensor maximum is 4.6 volts. Monitor the IAT2 PID value. A typical IAT2 sensor temperature should be greater than the IAT sensor temperature.
