Hva betyr feilkoden?
The engine control module uses the turbo control valve to keep the correct boost pressure in the inlet manifold. It compares the signal from the turbo position sensor with how the turbo is being commanded, and here the signal is too low for that position.
Mulige årsaker
- Vacuum hoses are leaking
- The turbo control valve is sticking
- The turbo control valve is damaged
- The position sensor is damaged
Hva du kan gjøre
- 1Start the engine and read the fault code with a diagnostic tool, noting whether it is active now or only stored
- 2Check the vacuum hoses to the turbo control valve for cracks, loose connections and leaks
- 3Check the connector at the turbo position sensor for looseness, corrosion and oxidation
- 4With a multimeter, check that the position sensor wiring has no open circuit and no short to ground
- 5Have a workshop with diagnostic equipment check the movement of the turbo control valve and whether the position sensor gives the correct signal
Symptomer du kan merke2
- The Check engine (malfunction indicator) lamp lights up
- Other warning lamps or warning chimes may also be triggered
