Mögliche Ursachen

Contact resistance or corrosion in the connectors
Open circuit in the signal wire
With fault code ECM-P120512: the signal wire is shorted to voltage, or the injection valve is damaged

Was Sie tun können

1Cylinder 5 is the fifth cylinder counted from the right-hand side of the vehicle, with cylinder 1 furthest from the flywheel.
2Check that the fuses are intact. Their location is in the owner's manual or on the fuse box cover.
3Check the connector to the cylinder 5 injection valve for contact resistance and corrosion.
4With the ignition off, use a multimeter to check that the signal wire to the cylinder 5 valve has no break and no contact with ground or voltage.
5If the fault remains, have a workshop check the cylinder 5 injection valve and its control.
