Co oznacza ten kod błędu?
The signal from fuel level sensor B is too low, because the left-hand sensor is shorted to earth. The code is generic and does not say what type of fault it is. The trip computer may show the tank empty too early, and the fuel level is shown wrongly.
Możliwe przyczyny
- The left-hand fuel level sensor is shorted to earth
Co możesz zrobić
- 1With a diagnostic tool, read the fuel level value in live data. If it stays still while the tank is filled, the sensor is suspect
- 2Check the fuel pump and level sensor fuses in the engine bay and in the CEM. If one has blown, check its circuit for a short to earth before replacing it
- 3Use a multimeter to check that the wire to the left-hand sensor has no contact with earth
- 4Check the connectors in the wiring to the fuel pump for corrosion and loose connections
- 5Compare the fuel gauge with the trip computer and note when the difference appears
- 6Work on the fuel pump is for a workshop, since the fuel system is flammable
Objawy, które możesz zauważyć2
- The trip computer shows the tank as empty too early
- A wrong fuel level is displayed
Na co może wpływać usterka1
- The fuel level is shown as zero
