Diagnostic Trouble Code (DTC) Charts and Descriptions
P0102 - Mass Or Volume Air Flow A Circuit Low
Description: This DTC sets when during key ON, engine running (KOER), the mass airflow (MAF) sensor output changes
below a minimum calibrated limit for greater than a set period of time.
Possible Causes: • MAF circuit short to ground
• Damaged MAF sensor
Diagnostic Aids: Make sure the MAF sensor connector is locked and seated correctly.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test DC.
P0103 - Mass Or Volume Air Flow A Circuit High
Description: This DTC sets when the mass airflow (MAF) sensor output changes above a maximum calibrated limit while the
engine is running.
Possible Causes: • MAF circuit open
• MAF circuit short to voltage
• Damaged MAF sensor
Diagnostic Aids: Make sure the MAF sensor connector is locked and seated correctly.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test DC.
P0104 - Mass Or Volume Air Flow A Circuit Intermittent/Erratic
Description: This DTC sets when a concern exists in the MAF circuit, or the air tube containing the mass airflow (MAF)
sensor, causing an incorrect sensor output reading.
Possible Causes: • MAF circuit intermittent open
• MAF circuit intermittent short to voltage
Diagnostic Aids: Check the MAF sensor tube for air leaks.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test DC.
P0106 - Manifold Absolute Pressure (MAP/BARO) Sensor Range/Performance
For Vehicles With 2.7L And 3.5L GTDI Engines
Description: This DTC sets when the MAP PID does not correlate with the BARO or the TCBP PID.
Possible Causes: • Slow responding manifold absolute pressure (MAP) sensor
• Damaged MAP sensor
Diagnostic Aids: This DTC may be accompanied by other DTCs. Check for other DTCs and diagnose those first.
For All Others
Description: This DTC sets when the manifold absolute pressure (MAP) sensor input does not correlate with an inferred
MAP value. The inferred value is based on the mass airflow (MAF) sensor.
Possible Causes: • Slow responding MAP sensor
• Damaged MAP sensor
• Damaged MAF sensor
Diagnostic Aids: This DTC may be accompanied by other DTCs. Check for other DTCs and diagnose those first.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test DM.
P0107 - Manifold Absolute Pressure (MAP)/Barometric Pressure (BARO) Sensor Low
Description: This DTC sets when the manifold absolute pressure (MAP) sensor operating voltage is below the minimum
calibrated parameter of 0.024 volt.
