Co oznacza ten kod błędu?
The ECM estimates the air mass it expects from a range of parameters and checks that estimate against the reading the mass air flow sensor gives. The code is stored once the air mass correction factor has become too low and the lambda adaptation has drifted above or below a fixed figure. The fault is mainly noticed as a lit eco indicator and reduced performance.
Możliwe przyczyny
- Contact resistance and oxidation in the mass air flow sensor connector terminals
- Air leak in the intake system
- Blocked intake system
- Damaged mass air flow sensor
Co możesz zrobić
- 1Read and note the code, clear it and road test to see whether it returns
- 2Check that the mass air flow sensor connector is fully engaged and free from oxidation
- 3Look for leaks in the hoses and joints between the mass air flow sensor and the throttle body, especially cracks and loose clamps
- 4Look for blockages in the intake system, for example deposits on the throttle body
- 5If the fault remains after the intake system is checked, have a workshop check the mass air flow sensor
Objawy, które możesz zauważyć2
- Eco indicator lamp lit
- The car runs poorly
Na co może wpływać usterka3
- Calculated boost pressure and calculated air mass are used
- Rear lambda sensor control is switched off
- Misfire diagnosis is switched off
