| DTC Strategy |
- Characteristic line strong shift
|
- Poor connection or damaged harness
- Front HO2S
|
| Enable Conditions |
- Wide range sensor pump current valid
- Downstream O2 sensor operative readiness
- Active test not activated
- engine speed > 600rpm
- Mass air flow < 83g/sec(300kg/h)
- 572 F(300°C) < Exhaust gas temperature < 1472 F (800°C)
|
| Threshold value |
- Plausibility between upstream and downstream
- Upstream lean & downstream rich & lambda controller limit or upstream rich & downstrean lean & lambda controller limit
