| DTC Strategy |
- Plausibility monitoring (monitor the graph when the fuel air ratio is lean)
|
- Poor connector connection
- Open or short circuit
- Faulty upstream O2 sensor
|
| Enable Conditions |
- Sensor ceramic temperature is higher than 730°C (1346°F)
- Exgust mass air flow is between 20 kg/h and 150 kg/h
- Catalyst temperature is at between 530°C (986°F) and 850°C (1562°F)
- Required lambda is equal to 1
|
| Threshold Value |
- Second control variable of downstream O2 sensor is lower than -7%
