DB Modern vehicles use oxygen sensors, often called lambda sensors, to monitor oxygen levels in the exhaust gases. This information helps the ECU adjust fuelling.
Signs of a sensor fault
- Engine warning light
- Poor fuel economy
- Emissions issues
- Poor running
- Failed MOT emissions
What to do next
If a warning light is present, diagnostic testing can help identify whether the sensor itself or another engine problem is responsible.
