| DTC Strategy |
- Plausibility monitoring, stuck in lean (monitor the vibration)
|
- Poor connector connection
- Open circuit of O2 sensor
- Faulty downstream O2 sensor
|
| Enable Conditions |
- Battery voltage is higher than 10.7V
- Check vibration
- Lambda control is 0.8 for 8s
- Voltage of downstream oxygen sensor is lower than 0.7V for 95s
- Fuel system feedback control
- Target catalyst temperature is 350°C to 925°C (662°F to 1697°F)
- Amount of air flow 6.94g/s
- Exhaust gas target temperature is higher than 350°C (662°F)
- Voltage of downstream O2 sensor is lower than 0.4V or higher than 0.5V
|
| Threshold Value |
- The sensor voltage is lower than 0.7V
