Co oznacza ten kod błędu?
The fault code shows that the canister purge valve or the EVAP canister shut-off valve is not working as it should, either through a leak or because the valve is clogged. The valves control fuel vapours between the fuel tank and the canister, which is the carbon filter. The fault is checked when the leak diagnostic is carried out and is stored if one of the components is faulty.
Możliwe przyczyny
- Leaking hoses at the canister purge valve
- Defective canister purge valve

- 4Have you got a diagnostic tool: activate the canister purge valve and the EVAP canister shut-off valve separately and check that each opens and closes
- 5Have a workshop with diagnostic equipment check the canister purge valve and the EVAP canister shut-off valve if the fault returns after these repairs
