Hva betyr feilkoden?
The engine control module (ECM) compares the measured charge pressure before the throttle with the calculated charge pressure after the throttle. The code is set when the ratio becomes incorrect, here with a signal that is too low. An air leak after the turbocharger, or a loose or damaged charge pressure sensor, may be behind it.
Mulige årsaker
- Air leak between the turbocharger and the throttle unit
- Loose charge pressure sensor, which measures atmospheric pressure
- Damaged charge pressure sensor
Hva du kan gjøre
- 1Clear the code, drive the car and read again to see whether it returns
- 2Check that the charge pressure sensor is firmly fitted and has not come loose
- 3Look for an air leak in the intake system between the turbocharger and the throttle unit
- 4If nothing is found, try a new charge pressure sensor
- 5If the fault remains, have a workshop diagnose further
Symptomer du kan merke1
- Poor performance
Hva feilen kan påvirke1
- Boost pressure is lower than normal
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
