| DTC Strategy |
- Transient time monitor(Rich to Lean)
|
- Poor connector connection
- HO2S (B1S2)
- ECM/PCM
|
| Enable Conditions |
- Battery voltage is greater than 10.7V
- Engine speed is at between 1200RPM and 3520RPM
- EGT around downstream O2S(Model) is greater than 300°C (572°F)
- Exhaust gas mass flow is greater than 10kg/h
- Δ Exhaust gas mass flow is at between -150kg/h and 150kg/h
- Fuel system status is same as Fuel cut-off
- Downstream O2S voltage before fuel cut-off is greater than 0.63V
|
| Threshold Value |
- Transient time(average): Minimum duration(1/Max gradient) of downstream O2S voltage from 0.63V to 0.25V during fuel cut off is greater than 0.5s (Average value of 3 samples)
|
| Diagnostic Time |
- 2 valid fuel cut-off phases
