Co oznacza ten kod błędu?
The code concerns the sensor in the right half of the tank, which is shorted to ground so that the signal becomes too low. The fault is intermittent, meaning it has occurred before but may not be present now. The fuel gauge then does not work, and the trip computer may show the tank as empty too early.
Możliwe przyczyny
- The sensor in the right half of the tank is shorted to ground
Co możesz zrobić
- 1Clear the fault code and test drive the car; if it does not come back there is nothing more to do
- 2Check the connectors at the sensor in the right half of the tank for chafing, loose contacts and corrosion
- 3Look for chafing on the wire to the right-side sensor, since a damaged wire can cause a temporary short to ground
- 4Use a multimeter to check that the wire to the right-side sensor has no contact with ground (the body)
- 5If the fault returns, have a workshop check the sensor and the wiring further
