Oxygen Sensor Monitoring



Oxygen Sensor Monitoring
The oxygen sensors are monitored for:
- Operational readiness
- Connectivity
- Short circuit to B+
- Short circuit to ground
- Open circuit
- Aging of oxygen sensors via the control frequency and control position

Monitoring of Sensor Aging


Effect Of Period Duration On Emission Values:






Contamination or aging of the oxygen sensor affects the sensor voltage or period duration of the sensor signal and therefore has a negative influence on emission values.
