| Main Action |
- Monitoring deviation between target idle and actual engine speed during catalyst heating.
|
- Restriction in intake or exhaust system
- Air leakage
- Checking operation of ETC
|
| Prerequisite condition |
- ECT at starting engine is higher than -10°C (14°F).
- Time elapsed after starting engine is longer than 9 seconds
- Vehicle speed is slower than 56.3 Km/h (35 mile/h)
- Accelerator 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 270 rpm (Engine speed is too low) and idle torque controller equals to 40 N.m.
- Current RPM is higher than target RPM as much as 500 rpm (Engine speed too high) and idle torque controller equals to -20 N.m.
