Hva betyr feilkoden?
The fault concerns the control of the injection valve for cylinder 4. The engine control module (ECM) drives it through internal output stages and detects when something is wrong. The causes are contact resistance and corrosion at the 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
- 1Check the connector to the cylinder 4 injection valve for contact resistance and corrosion.
- 2With the ignition off, disconnect the connector and check that the contact surfaces are clean.
- 3With the ignition off, use a multimeter to check that the signal wire has no break and is not shorted to ground.
- 4If you have a diagnostic tool, read the status of the cylinder 4 injection valve with the engine running.
- 5Cylinder 4 is the fourth cylinder counted from the right-hand side of the vehicle, with cylinder 1 furthest from the flywheel.
- 6If nothing is found in these checks, the cause may lie in the engine control module, so have a workshop check it.
