4-20 Powertrain DTC Charts and Descriptions
Diagnostic Trouble Code (DTC) Charts and Descriptions
P00E0 - Charge Air Cooler Coolant Temperature Sensor Circuit Low (Continued)
Diagnostic Aids: A CAC coolant temperature sensor reading less than the self-test minimum with ignition ON, engine OFF or
during any engine operating mode indicates a concern is present.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test KP.
P00E1 - Charge Air Cooler Coolant Temperature Sensor Circuit High
Description: This DTC sets when the charge air cooler (CAC) coolant temperature is less than a calibrated value or a short
to voltage is detected in the CACCTS circuit.
Possible Causes: • CACCTS circuit open
• CACCTS circuit short to voltage
• Damaged CAC coolant temperature sensor
Diagnostic Aids: A CAC coolant temperature sensor reading greater than the self-test maximum with ignition ON, engine OFF or
during any engine operating mode indicates a concern is present.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test KP.
P00E2 - Charge Air Cooler Coolant Temperature Sensor Intermittent/Erratic
Description: This DTC sets when the charge air cooler (CAC) coolant temperature sensor signal changes from an in range
value to beyond the minimum or maximum calibrated limit a calibrated number of times.
Possible Causes: • CACCTS circuit intermittent open
• CACCTS circuit intermittent short to ground
• CACCTS circuit intermittent short to voltage
• Damaged CAC coolant temperature sensor
• Damaged CAC coolant temperature sensor wiring
Diagnostic Aids: Check the harness and connection. Monitor the sensor PID while wiggling and bending the harness from the
sensor to the PCM.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test KP.
P0100 - Mass Or Volume Air Flow A Circuit
Description: This DTC sets when the mass airflow (MAF) sensor frequency changes below a minimum calibrated limit for
greater than 0.5 seconds.
Possible Causes: • Damaged MAF sensor element
• Intake air system components incorrectly connected
Diagnostic Aids: Install a new mass airflow/intake air temperature (MAF/IAT) sensor. Refer to the Workshop Manual Section
303-14, Electronic Engine Controls.
Application Key On Engine Off Key On Engine Running Continuous Memory
All Refer to the Description, Possible Causes and Diagnostic Aids for the DTC.
P0101 - Mass Or Volume Air Flow A Circuit Range/Performance
Description: This DTC sets when the actual airflow is less or greater than the modeled airflow by greater than a calibrated
value for 2.4 seconds.
Possible Causes: • Restricted airflow
• Intake air system leak
• Damaged mass airflow (MAF) sensor
Diagnostic Aids: Check the MAF sensor for contamination and the intake air system for leaks.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test DC.
