| DTC Strategy |
- Signal rationality with lean mixture (During Fuel Cut Off)
|
- Poor Connector Connection
- Faulty Downstream O2 Sensor
|
| Enable Conditions |
- Downstream O2 sensor operative readiness detected (sensor element resistance lower than 1kΩ or heater max heating or normal heating for higher than 75s.)
- Integrated mass air flow since last fuel cut off higher than 500g
- Integrated mass air flow since fuel cut off begin higher than 12g and lower than 250g
- Battery voltage higher than 11V and lower than 16V
- No relevant DTC present
|
| Threshold Value |
- Downstream O2 sensor voltage higher than 0.2V
