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 greater than 10 to 60%
- Engine speed is between 470 RPM and 6700 RPM
- Barometric pressure (BARO) is greater than 75 kPa
- Engine load ratio gradient is less than 12 to 60% /s
- Throttle gradient/sec. is less than 58.6 to 1265.6% /s
- Coolant temperature is higher than -7°C (19.4°F)
- Battery voltage between 10 V and 16 V
- No relevant failure
- Fuel cut-off not active
|
| Case 1 |
Threshold Value |
- Misfire rate is greater than 2.0% pre 1000 revolutions
|
| MIL On Condition |
- Immediate (Misfire enough to damage the catalyst)
|
| Case 2 |
Threshold Value |
- Rate of misfire per 200 revolutions is greater than 10~50% in driving condition
|
| Diagnosis Time |
- 2 Driving Cycles (Misfire breaking the emission regulation)
