Hva betyr feilkoden?
The engine control module has registered a fault in the signal circuit to the turbocharger control valve, such as a short to ground or an open circuit. The code can also be set when the measured intake air quantity is unreasonably high. The fault affects boost pressure, and engine output may be limited.
Mulige årsaker
- Leaks at the intake manifold, in the hoses or at their connections
- Damaged turbocharger control valve
Hva du kan gjøre
- 1With the ignition off, look for air leaks in the intake between the turbo and the intake manifold
- 2Check that the hoses and connections on the intake are secure and have no cracks
- 3Check the connector to the turbo control valve for looseness and oxidation
- 4If the fault returns although the hoses and connectors are sound, have a workshop check the turbo control valve
Symptomer du kan merke2

- Warning symbol and text message in the display
Hva feilen kan påvirke1
