| DTC Strategy |
- Signal plausibility with rich mixture (During catalyst purge after fuel cut-off)
|
- Poor connection or damaged connector
- HO2S contamination
|
| Enable Conditions |
- Downstream O2 sensor operative readiness detected
- Integrated mass air flow since fuel cut-off begin is at between 12 and 250g
- Integrated mass air flow in last fuel cut-off higher than 500g
- Battery voltage is at between 11 and 16V
|
| Threshold Value |
- Downstream HO2S higher than 0.2V during fuel cut-off phase
