| DTC Strategy |
- Characteristic Monitoring
|
- Poor Connector Connection
- Faulty Upstream O2 Sensor
|
| Enable Conditions |
- Downstream O2 sensor operative readiness
- Engine speed is higher than 600 RPM
- Mass air flow is less than 83g/s (300kg/h)
- Exhaust gas temp. is between 300°C (572°F) and 800°C (1472°F)
- After fuel-cut, catalyst purge is not working
- Stabilization Conditions
- Absolute value (engine rpm-filtered engine rpm) is lower than 500 rpm
- Absolute value (Air mass-filtered air mass) is lower than 0.4 g/rev (200mg/stk)
- Absolute value (Lambda value-filtered lambda value) is less than 15%
|
| Threshold Value |
- Plausibility between upstream and downstream
- Upstream lean & downstream rich & lambda controller limit or upstream rich & downstrean lean & lambda controller limit
|
| Diagnostic Time |
- 5 to 100s depending on intake air mass
