Hva betyr feilkoden?
The ECM continuously checks that the mass air flow sensor signal is plausible. The code is stored when the signal is wrong, and the fault here is a voltage that is too high. A fault on the swirl flap can also cause the code to be set. The results are that engine torque may be limited and a calculated air mass value is used.
Mulige årsaker
- If this code is set together with ECM-P029900, the cause is probably a leak in the hose or joint between the turbocharger and the intake valves
- Camshaft in the wrong position
- Damaged mass air flow sensor
Hva du kan gjøre
- 1Read and note the code, clear it and road test to see whether it returns
- 2Look for leaks: cracked hoses and loose clamps on the hoses and joints between the turbocharger and the intake pipe
- 3Check that the connector at the mass air flow sensor is fully engaged and free from corrosion
- 4With a multimeter, check that the signal wire to the sensor is not shorted to supply voltage
- 5If the fault remains, have a workshop check the camshaft position and the mass air flow sensor
Symptomer du kan merke1
- The car lacks power and runs poorly
Hva feilen kan påvirke2
- Engine torque may be limited
- The control module uses a calculated air mass value in place of the sensor signal
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
