| DTC Strategy |
- Monitor HO2S's signal (Downstream O2 sensor signal is too low)
|
- Poor Connection
- Faulty HO2S
- Clogging of fuel filter in fuel
- Faulty ECM (PCM)
|
| Enable Conditions |
- Fuel cut off is not activated
- Full load is not activated (gas pedal value is less than or equal to 90%)
- Catalyst overheating prevention is not activated
- Battery voltage is between 11V and 16V
|
| Threshold value |
- Downstream O2 sensor voltage is lower than 0.75V when lambda set point is equal to 0.8
|
| Diagnosis Time |
- 7 seconds after lambda set point shift to corresponding side
|
| MIL On Condition |
