Co oznacza ten kod błędu?
The engine control module (ECM) continuously compares the signals from the mass airflow meter and the charge pressure sensor and checks that they are reasonable. The code is set when drift is detected in the measured value, which may be caused by a leak in the intake system.
Możliwe przyczyny
- Air leaks in the intake system
- Loose, resistive or oxidised terminals
- Damaged charge pressure sensor
- Damaged mass airflow meter
Co możesz zrobić
- 1Clear the code, drive the car and read again to see whether it returns
- 2Look for an air leak in the intake system, for example loose hose clamps and cracked hoses
- 3Check the connectors to the mass airflow meter and the charge pressure sensor for looseness, contact resistance and oxidation
- 4If you have a diagnostic tool: read the airflow and the boost pressure in live data with the engine running and check that they follow each other
- 5If the fault remains, have a workshop diagnose further, since the sensors may need checking with equipment
Objawy, które możesz zauważyć3
- Poor performance and lack of power, especially when starting off
- The car hesitates, surges or runs roughly during acceleration or deceleration
- Warning symbol and text message in the display
Na co może wpływać usterka1
- Engine torque is limited
