|
| Case 1 |
Enable Conditions |
- Battery voltage is higher than 10.7V
- Engine speed is between 1200 RPM and 3520 RPM
- EGT around downstream O2S is higher than 425°C (797° F)
- Downstream O2S voltage before fuel cut is higher than 0.15V
- Integrated Exhaust gas mass flow is higher than 0.2kg/h
- Delta exhaust gas mass flow is between -150kg/h and 150kg/h
- Fuel cut off
- Downstream O2S voltage before fuel cut is higher than 0.63V
|
| Threshold Value |
- Response Time is higher than 0.3 sec (Duration of Downstream O2S voltage from above 0.63V to 0.25V during fuel cut off)

- Downstream O2S voltage before fuel cut is higher than 0.15V
- Integrated Exhaust gas mass flow is higher than 8kg/h
- Delta exhaust gas mass flow is between -30kg/h and 50kg/h
- After fuel cut-off
- Downstream O2S voltage After fuel cut-off is lower than 0.25V
|
| Threshold Value |

|
| Diagnostic Time |
- When the fuel cuts 3 times
