Hva betyr feilkoden?
The ECM continuously monitors the voltage of the rear oxygen sensor on bank 1, which is the cylinder row at the front with cylinders 1, 3, 5 and 7. The code is set when the voltage falls outside the range the ECM accepts, or when the sensor wrongly shows a lean mixture.
Mulige årsaker
- Contact resistance or oxidation in the connections
- Signal wire shorted to ground
- Broken signal wire
- Damaged rear oxygen sensor on bank 1
- Air leak in the intake pipe
Hva du kan gjøre
- 1If you have a diagnostic tool: start the engine, let it idle for a while, then read the fault status. Malfunction found means the fault is present now
- 2Do not use rust solvent spray or grease in the oxygen sensor connector, and check that it is firmly seated and free from oxidation
- 3Inspect the signal wire for chafing, and use a multimeter to check that it is unbroken and has no contact with ground
- 4Look for air leaks in the intake pipe, for example at hoses and connections
- 5If you find nothing above: try a new rear oxygen sensor, or have a workshop replace it
Symptomer du kan merke1
- Malfunction indicator (MIL) lamp is lit
Hva feilen kan påvirke1
- Control of the rear oxygen sensor is switched off
