Hva betyr feilkoden?

The ECM monitors the injection system and its parts. The code is set when the cylinder 1 injector circuit has a short. This may be caused by short circuits in the supply, ground or signal wiring, or by an internal short circuit in the injector.

Mulige årsaker

Supply wire shorted to ground
Supply wire shorted to voltage
Ground wire shorted to voltage
Signal wire shorted to ground
Signal wire shorted to voltage
Internal short circuit in the injector

2Use a multimeter to check whether the wires to injector cylinder 1 are shorted to ground or voltage, with the engine control module connector disconnected
3Inspect the wires to injector cylinder 1 for chafing and pinching, especially where they may have touched each other
