| DTC strategy |
- Determine ir a muliple cylinder misfire or a cylinder specific misfire is occurring by monitoring cranckshaft acceleration
|
- Faulty Spark plugs
- Faulty Spark plug cables
- Air Leakage
- Belt deflection and Air gap of CKPS
- Incorrect timing
- Faulty injector
- Improper engine compression
- Faulty PCM
|
| Enable condition |
- No sudden change in throttle opening
- Torque management control is not functioning
- Not deceleration fuel cut-off
- Not fuel cut-off during high speed operation
- Not negative torque driving conditions
- Not fuel level low
- TEC is learned
- Coolant temperature is outside the window
- 500 rpm < Engine speed < 6600 rpm
- 11V < Battery voltage < 16V
- TPS/MAP sensor/CAMS/CKPS/ECTS are normal.
