- 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 3.33 g/sec
- Total flow exhaust gas: -25 g/sec ~ 25 g/sec
- Fuel cut
- Downstream O2S voltage before fuel cut is higher than 0.55V
|
| Threshold Value |
- When the O2 mass accumulated when the oxygen sensor (down) voltage changes from 0.55 V to 0.15 V during the fuel cutoff is equal to or greater than the reference value
|
| Diagnostic Time |
- 3 valid fuel cut-off phases
