| DTC Strategy |
- Monitoring deviation between target idle speed and actual engine speed during catalyst heating
|
- Restriction in intake or exhaust system
- Air leakage
- Checking operation of ETC
|
| Enable Condition |
- Catalyst heating (ECT at engine start is between -10°C (14°F) and 43°C (109.4°F))
- Time after start is loner than 9s
- Vehicle speed is slower than 56.32km/h (35mph)
- Gas pedal value is less than 0.01% (Pedal is not pushed at all)
|
| Threshold Value |
- Current RPM is lower than target RPM as much as 270RPM (Engine speed is too low) and idle torque controller is equal to 40Nm during 5s
- Current RPM is higher than target RPM as much as 500RPM (Engine speed too high) and idle torque controller is equal to -20Nm during 5s
