Hva betyr feilkoden?

Although the code is named signal bias or zero adjustment failure, the two oxygen sensors give conflicting pictures of the mixture. The ECM compares the adaptation values of the front and rear sensors, and the code is set when they deviate too much. The fault may lie in the front or rear sensor circuit.

Mulige årsaker

Leakage in the exhaust system
Oxygen sensor indicates an incorrectly lean mixture
Damaged oxygen sensor

Hva du kan gjøre

1Check the wiring to the oxygen sensors for damage, chafing and loose connectors
2If you have a diagnostic tool: read the oxygen sensor signals in live data with the engine running and see whether they differ more than they should
3Check the exhaust system for leaks, since air in the exhaust can give a wrong signal
4If the fault remains, have a workshop establish whether the engine control module has an internal fault

Symptomer du kan merke1

Check engine warning lamp lights or behaves abnormally

Hva feilen kan påvirke2

Oxygen sensor control is switched off
Catalytic converter diagnostics are switched off

Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
