Hva betyr feilkoden?
The ECM monitors the circuit to the injector for cylinder 1. The fault code is set when the signal is missing in that circuit, and the engine may then not run on all cylinders.
Mulige årsaker
- Contact resistance in the connections
- Open circuit in the signal wire to the injector
- Open circuit in the power supply to the injector
- Damaged injector
- Damaged mass air flow (MAF) sensor
Hva du kan gjøre
- 1Read and note the code, clear it and road test to see whether it returns
- 2Check the connector at the injector for cylinder 1 for contact resistance and loose connections
- 3Use a multimeter to check that the wire to the injector for cylinder 1 has no open circuit
- 4If you have a diagnostic tool: activate the injector for cylinder 1 with ignition on and the engine off, and listen for a clear click
- 5If the fault remains, have a workshop check the injector and the mass air flow sensor
Symptomer du kan merke2
- The malfunction indicator lamp (MIL) is on
- The engine is not running on all cylinders
