Hva betyr feilkoden?
The engine control module (ECM) controls boost pressure by sending a signal to the turbo control valve. The fault is set when turbo system boost is excessive. The cause may be a leak in the intake, blocked hoses or a damaged turbo control valve.
Mulige årsaker
- Air leak in the intake system
- Blocked hoses to the turbocharger or the turbo control valve
- Damaged turbo control valve
Hva du kan gjøre
- 1Read the code, clear it and road test to see whether it returns
- 2With the engine at idle, listen for a hissing sound from the intake, which can point to an air leak
- 3Look at the hoses to the turbocharger and turbo control valve for blockages, kinks and loose connections
- 4If you have a diagnostic tool: activate the turbo control valve and check that it clicks as it operates
- 5If the fault remains, have a workshop check the turbo control valve with diagnostic equipment
Symptomer du kan merke3
- The check engine lamp comes on or behaves abnormally
- Warning symbol and text message in the display
