Was bedeutet der Fehlercode?

The engine control module (ECM) monitors the signal to the injectors and sets the code when the signal reads above the threshold. The cause can be a signal wire or earth wire shorted to supply voltage, or a damaged injector.

Mögliche Ursachen

Signal wire short-circuited to supply voltage
Earth wire short-circuited to supply voltage
Damaged injector

Was Sie tun können

1Check that the fuses are intact.
2Look for chafed or pinched wires, especially where the signal and earth wires could have touched supply voltage.
3Have a workshop measure whether the signal and earth wires have contact with voltage, as this needs a measurement with the ignition on.
4If you have a diagnostic tool, activate the injectors one at a time and see whether they respond.
5If the wiring is undamaged, have a workshop check the injectors.

Symptome, die Sie bemerken können4

Uneven idle
Poor performance, the car lacks power
The engine hesitates, surges or runs unevenly, at unclear times
The engine does not start, and when the fault shows is unclear
