Co oznacza ten kod błędu?

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

Możliwe przyczyny

Leak in the exhaust system
Damaged rear oxygen sensor

Co możesz zrobić

1Read the code, clear it and road test the car to see whether it comes back
2Look for air leaks in the exhaust system, as a leak can give a wrong signal from the rear sensor
3Avoid rust solvent spray and grease in the rear sensor connector and check that it is fully engaged
4If no leak is found, replace the rear oxygen sensor; a damaged sensor can also set the code
