Hva betyr feilkoden?
The ECM compares the signal from the engine speed sensor with the signal from the camshaft sensor. If the engine speed sensor signal is unreasonable compared with the camshaft sensor, fault code ECM-1807 is set.
Mulige årsaker
- Signal wire short-circuited to voltage
- Signal wire short-circuited to ground
- Open circuit in the signal wire
- Engine speed sensor incorrectly installed
- Defective engine speed sensor
Hva du kan gjøre
- 1Switch off the ignition and check the engine speed sensor connector for play and oxidation
- 2With a multimeter, check that the signal wire from the engine speed sensor is not broken or shorted to ground or voltage
- 3Check that the engine speed sensor is correctly mounted and not loose
- 4If you have a diagnostic tool: check in live data that the engine speed and the camshaft sensor signal agree with the engine idling
- 5If the fault remains, have a workshop replace the engine speed sensor
Symptomer du kan merke2
- The engine does not start
- The engine stalls
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
