Hva betyr feilkoden?
The ECM follows the voltage from the rear oxygen sensor on bank 2, the cylinder row at the rear. The code is set when the sensor reads rich incorrectly, or when the voltage falls outside the range the ECM accepts.
Mulige årsaker
- Signal wire shorted to voltage
Hva du kan gjøre
- 1If you have a diagnostic tool: let the engine idle for a while, then read the fault status once the diagnosis is complete
- 2Do not use rust solvent spray or grease in the oxygen sensor connector
- 3Check the signal wire between the control module and the rear oxygen sensor on bank 2 with a multimeter, to see that it does not short to voltage
- 4If the fault remains after these checks: have a workshop replace the rear oxygen sensor
Symptomer du kan merke1
- Malfunction indicator (MIL) lamp is lit
Hva feilen kan påvirke1
- Control of the rear oxygen sensor on bank 2 is switched off
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
