Co oznacza ten kod błędu?
The engine control module continuously compares the signals from the mass airflow meter and the boost pressure sensor with a calculated value. If the measured value drifts away, the fault code is stored. The fault may be caused by an air leak in the intake system or by a damaged sensor or meter.
Możliwe przyczyny
- Air leaks in the intake system
- Poor connections, contact resistance or corroded terminals
- Damaged boost pressure sensor
- Damaged mass air flow meter
Co możesz zrobić
- 1Look for air leaks in the intake system, such as loose hoses and clamps
- 2Check the connector at the air mass meter for play, contact resistance and oxidation, and clean it if needed
- 3Have a workshop check the boost pressure sensor, since it can also cause the fault code
- 4If the connector and intake system are in order but the fault remains, the air mass meter may be damaged. Have a workshop assess it
- 5Clear the fault code after the work and drive the car to see whether it comes back
