Hva betyr feilkoden?
The code concerns the injection valve for cylinder 2. The engine control module (ECM) drives it through internal output stages and sets the code when it finds a fault in that control. The cause may be poor contact at the valve connector, or the valve being clogged or leaking.
Mulige årsaker
- Contact resistance and corrosion in the injection valve connector
- The injection valve is clogged or leaking
Hva du kan gjøre
- 1Cylinder 2 is the second cylinder counted from the right-hand side of the vehicle, with cylinder 1 furthest from the flywheel.
- 2Check the connector to the cylinder 2 injection valve for contact resistance and corrosion.
- 3With the ignition off, disconnect the connector and check that it is not damp or corroded.
- 4With the ignition off, use a multimeter to check that the signal wire has no break and is not shorted to ground.
- 5If you have a diagnostic tool, read the status of the cylinder 2 injection valve with the engine running.
- 6If nothing is found in these checks, the cause may lie in the engine control module, so have a workshop check it.
