| DTC Strategy |
- Monitoring deviation between target idle speed and actual engine speed during catalyst heating
|
- Checking leakage of air intake
- Checking operation of ETC
|
| Enable Conditions |
- Coolant temperature is higher than -14°F
- Catalyst heating operating condition (during 20 sec immediately after cold start in 77°F range)
|
| Threshold value |
- Current RPM is lower than target RPM as much as 270RPM (Engine speed too low)
- Current RPM is higher than target RPM as much as 270RPM (Engine speed too high)
