Co oznacza ten kod błędu?
The engine control module (ECM) has detected that the two rear oxygen sensors have been swapped between bank 1 and bank 2. This can happen if the sensors were fitted incorrectly after service, but the fault can also be set if both sensors are damaged. The fault is diagnosed once the engine has been idling for a while.
Możliwe przyczyny
- The rear oxygen sensors are fitted in the wrong bank
- Both rear oxygen sensors are damaged
Co możesz zrobić
- 1Visually check that the rear oxygen sensors are not swapped between bank 1 and bank 2
- 2If you have a diagnostic tool: read the voltage of each rear oxygen sensor in live data with the engine idling and compare them with each other
- 3Check that the connectors to both sensors are secure and free from oxidation
- 4If the fault remains with the sensors correctly fitted, have a workshop decide whether the sensors need replacing
Objawy, które możesz zauważyć1
- Malfunction indicator lamp (MIL) lit
Na co może wpływać usterka2
- Oxygen sensor control is switched off
- Catalytic converter diagnostics are switched off
