| DTC Strategy |
- Maximum error of diagnosis of engine efficiency for catalyst heating during idle
|
- Intake air restriction
- Exhaust restriction
- Engine mechanical concern
- Damaged or sludgy throttle body
- Vacuum leaks
- Damaged ECM
|
| Enable Conditions |
- Vehicle speed is same as 0km/h (0mph)
- Accelerator pedal is 0%
- After catalyst heating is greater than 0s
- Catalyst heating is active
- ECT at start is between -12 and 42°C (10.4 and 107.6°F)
- IAT is greater than -12°C (10.4°F)
- Barometric pressure is greater than 75.4kPa
- Modelling catalyst temperature is lower than 300°C (572°F)
|
| Threshold Value |
- Average of spark efficiency deviation is greater than 40% during 10s
