| DTC Strategy |
- Rationality check, stuck lean (oscillation check)
|
- Poor connector connection
- HO2S (Bank1, Sensor2)
|
| Enable Conditions |
- Vehicle speed 40 km/h (24.85 mph)
- Engine speed 832 to 3360 RPM
- Atmospheric pressure is higher than 75 kPa
- HOS2 sensor activation status
- The temperature of the upstream HOS2 sensor tip is higher than 800°C (1472°F)
- When the upstream HOS2 sensor heating time is higher than 30 seconds, it is in the maximum heating or normal heating state.
- The temperature of the downstream HOS2 sensor tip is higher than 620°C (1148°F)
- When the downstream HOS2 sensor heating time is more than 80 seconds and is in the maximum heating or normal heating state.
- Catalyst temperature (model) is between 520 to 957°C (968 and 1754.6°F)
|
| Threshold Value |
- Downstream O2S voltage is lower than 0.82V
