| DTC Strategy |
- Slow response (Switching time check at entry in fuel cut off)
|
- Leak in intake or exhaust system
- Faulty fuel system
- Front and rear HO2S connections revolutionizers
- Poor connection or damaged connector
- HO2S contamination
|
| Enable Conditions |
- Coolant temperature is higher than 73°C (163°F)
- Downstream O2 sensor readiness detected
- Downstream O2 sensor pre-heating phase finished
- Catalyst temperature model is higher than 400°C (752°F)
- Downstream O2 sensor signal is higher than 0.6V at entry into fuel cut-off
- No relevant failure
- Battery voltage is higher than 10V and lower than 16V
|
| Threshold Value |
- Average ratio between measured and maximum allowed rich to lean switching time entering fuel cut-off is higher than 1
|
| Diagnostic Time |
- 4 valid fuel cut-off phases

| MIL ON Condition |
