Was bedeutet der Fehlercode?
The ECM checks the front oxygen sensor's signal while closed-loop fuel control is active. If the sensor does not activate, or activates too slowly, the code is set. The cause may be a defective oxygen sensor or poor contact in the connectors.
Mögliche Ursachen
- Defective front oxygen sensor
- Contact resistance in the connections
Was Sie tun können
- 1Read and clear the fault code and check whether it returns
- 2Check that the connectors at the oxygen sensor and the engine control module are free from oxidation and contact resistance; do not use penetrating spray or grease on the connector
- 3If you have a diagnostic tool, read the oxygen sensor value in live data with the engine running and see whether it changes
- 4If the connectors are in good condition but the fault remains, have a workshop check the oxygen sensor
Symptome, die Sie bemerken können1
- The malfunction indicator lamp (MIL) is lit
Was der Fehler beeinflussen kann1
- Fuel trim control is switched off
