Hva betyr feilkoden?
The ECM keeps an eye on the feed voltage going to the fuel pressure sensor. If there is a fault in the supply, fault code ECM-1809 is set. The fault may lie in the supply wire, the sensor or the control module.
Mulige årsaker
- Power supply wire short-circuited to system voltage
- Power supply wire short-circuited to ground
- Defective fuel pressure sensor
- Defective engine control module
Hva du kan gjøre
- 1Switch off the ignition and check the fuel pressure sensor connector for play, contact resistance and oxidation
- 2With a multimeter, check that the supply wire to the sensor is not shorted to ground or to system voltage
- 3Look along the supply wire to the fuel pressure sensor for chafed or pinched spots
- 4If the fault remains, have a workshop check the fuel pressure sensor and the control module
Symptomer du kan merke2
- The engine cuts out
- The engine does not start
Hva feilen kan påvirke1
- The control module uses a fixed value for fuel pressure
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
