| DTC Strategy |
- Rich to Lean Response Rate check
|
- Leak in intake or exhaust system
- Faulty fuel system
- Front and rear HO2S connections reversed.
- Poor connection or damaged connector
- HO2S contamination
|
| Enable Conditions |
- Downstream O2 sensor operative readiness
- Downstream O2 sensor internal resistance is lower than 3kΩ
- Catalyst temperature model is higher than 400°C (752°F)
- Mass air flow is between 10 kg/h to 50 kg/h
- Integrated O2 load at not rich to lean
- Downstream O2 sensor signal is higher than 0.6V at entry into fuel cut-off
- Battery voltage is higher than 11V and lower than 16V
|
| Threshold Value |
- Signal gradient from 0.6V to 0.3V at entering fuel cut off out of range (average of signal gradient is lower than 1500 mV/s)
|
| Diagnostic Time |
