Was bedeutet der Fehlercode?
The ECM monitors the circuit to the injector for cylinder 1. The fault code is set when the signal in that circuit is too high, which can be caused by a wire shorted to supply voltage or a damaged injector.
Mögliche Ursachen
- Signal wire short-circuited to supply voltage
- Damaged injector
Was Sie tun können
- 1Read and note the code, clear it and road test to see whether it returns
- 2Inspect the wire to the injector for cylinder 1 for chafing and pinching where it may have shorted to supply voltage
- 3Use a multimeter to check that the wire to the injector for cylinder 1 is not shorted to supply voltage with ignition on
- 4If you have a diagnostic tool: read the signal for the cylinder 1 injector in live data with ignition on and see whether it is abnormally high
- 5If the wire is intact, have a workshop check the injector
Symptome, die Sie bemerken können2
