Hva betyr feilkoden?

Although the code is named for a low signal, it concerns the rear oxygen sensor in bank 1, sensor 2, which shows a lean mixture too late. The engine control module (ECM) checks the sensor and changes the mixture if the sensor does not show lean. At fuel cut-off the sensor should show a lean mixture, and if the switch takes too long the code is set.

Mulige årsaker

Leak in the exhaust system
Damaged rear oxygen sensor

Hva du kan gjøre

1Read the code, clear it and road test the car to see whether it comes back
2Check the exhaust system for air leaks; a leak before the rear sensor can give a wrong signal
3Check the connector to the rear sensor and do not use rust solvent spray or grease in it
4If no leak is found, try a new rear oxygen sensor, as a damaged sensor can also set the code
