| DTC Strategy |
- MAX-Error of diagnosis of engine efficiency for catalyst heating during idle
|
- Intake air restriction
- Exhaust restriction
- Engine mechanical concern
- Damaged or sludged throttle body
- Vacuum leaks
- Damaged PCM
|
| Enable Conditions |
- Engine speed is greater than 450rpm.
- Normal battery voltage.
- Engine speed gradient delay counter is greater than 12.
- Change in commanded spark is less than 5 deg.
|
| Threshold value |
- Average of spark efficiency deviation during 10sec(Difference of Actual efficiency and Target efficiency) greater than Threshold(ECT at Start) Ref.)
Eng. Temp. at start -9.8°C(14.36°F) = Efficiency 0.5%
Eng. Temp. at start 9.8°C(49.64°F) = Efficiency 0.5%
Eng. Temp. at start 15°C(59°F) = Efficiency 0.5%
Eng. Temp. at start 40°C(104°F) = Efficiency 0.5%
