Hva betyr feilkoden?
The ECM monitors the reading from the fuel pressure sensor. If it registers that the signal is too low, the code is set. The fault may be a signal wire shorted to ground, an open circuit, poor contact or a damaged sensor.
Mulige årsaker
- The signal wire is shorted to ground
- Open circuit in the signal wire
- Poor contact at the connectors, with resistance or oxidation
- Damaged fuel pressure sensor
Hva du kan gjøre
- 1Clear the code, road test the car and see whether it returns
- 2With diagnostic equipment, read the code's fault status after the test drive to see whether the fault is still present
- 3Check the connectors at the control module and the fuel pressure sensor for contact resistance and oxidation
- 4Use a multimeter to check that the signal wire between the control module and the fuel pressure sensor has no open circuit and is not shorted to ground
- 5Have a workshop replace the fuel pressure sensor if the connectors and wiring are intact
Symptomer du kan merke5
- Malfunction indicator lamp (MIL) on
- The engine misfires
- Poor performance and lack of power, especially when pulling away from a standstill
- The engine hesitates, surges or runs unevenly during acceleration or deceleration
- The engine is hard to start or does not start
Hva feilen kan påvirke2
- The fuel pressure is held at a fixed value
- The signal sent to the fuel pump control module is replaced by a calculated value
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
