| Main Action |
|
- Poor contact of connector
- Leak in intake or exhaust system
- O2 Sensor (Down)
|
| Prerequisite Condition |
- 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 6.11g/sec
- Delta exhaust gas mass flow is between -8.3g/sec and 13.9g/sec
- Fuel cut in
- Downstream O2S voltage before fuel cut is lower than 0.25V
|
| Threshold Value |
- Transient Time is higher than Threshold (Duration of O2 Sensor (Down) voltage from 0.25V to 0.66V during fuel cut in)
