Diesel Intake Air Flow Position Sensor Minimum/Maximum Stop Performance

Where it lives

For P02FA, the description names the sensor as the part involved.

Check these first

• A dirty or contaminated flap position sensor
• A sticking intake air flap at the stop
• Intake manifold leaks or blockages
• Sensor wiring or connector damage
• A faulty ECM or calibration

What to do next

1. Read the flap position sensor at both stops on a scan tool
2. Clean the sensor and flap assembly
3. Inspect the intake manifold for leaks or blockages
4. Check the sensor wiring and connector
5. Recalibrate the sensor to the ECM
6. Clear the code and retest
