|
- Poor connection
- B2S2
- ECM
|
| Enable Condition |
- Battery voltage is higher than 11V
- Engine speed is between 1080 RPM and 3520 RPM
- EGT around downstream O2S is higher than 400°C (752°F)
- Exhaust gas mass flow is higher than 6.11 g/sec
- Total flow exhaust gas: -2.78 g/sec ~ 13.89 g/sec
- When fuel injection is restarted after fuel cut-off
- Downstream O2S voltage before fuel cut is higher than 0.15V
- Fuel shut-off time 15 seconds or less
|
| Threshold Value |
- When the oxygen sensor (down) voltage is changed from 0.15V to 0.55V during re-injection after fuel cut-off, the accumulated O2 mass is output above the reference value
|
| Diagnostic Time |
- 3 valid fuel cut-off phases
