Detecting Condition |
Possible Cause |
| DTC Strategy |
- Calculation of engine roughness
|
- Faulty spark plugs or Ignition coil
- Incorrect valve timing
- Uneven compression
- Air leakage
- Improper fuel pressure or dirty fuel
- Blocked/Leaking injectors
- Leakage between cooling system and cylinder
|
| Enable Conditions |
- Engine load ratio is at between 10 and 85%
- Engine speed is at between 470 and 6700RPM
- Barometric pressure (BARO) model is higher than 75 kPa
- Engine load ratio gradient is less than 12 to 60%/s
- Throttle gradient is less than 58.6 to 1265.6%/s
- Coolant temperature is higher than 20°C (68°F) if start temperature is lower than -7°C (19°F)
- No rough road condition (moving mean value of vehicle speed gradient is less than 13 to 25%)
- Fuel cut-off not active
- Battery voltage is at between 11V and 16V
|
| Threshold Value |
- Misfire detected on 2 or more cylinders
|
| Diagnostic Time |
|
| MIL ON Condition |
- Immediately (misfire enough to damage the catalyst)
- 2 driving cycles (misfire breaking the emission regulation)
