| Main Action |
- Calculate the misfire rate (a misfire took place in more than 2 cylinders)
|
- Ignition plug or coil
- Valve timing
- Compression pressure
- Air leak
- Fuel (injector)-related parts
- Cooling system
|
| Prerequisite Condition |
- Engine speed is higher than 100 RPM and lower than 6500 RPM
- Engine load is higher than Zero torque line
- Coolant temperature is higher than -10°C (14°F)
|
| Case 1 |
Threshold Value |
- Misfire rate is greater than 3% pre 1000 revolutions
|
| Diagnostic Time |
|
| MIL |
|
| Case 2 |
Threshold Value |
- Rate of misfire per 200 revolutions is greater than 6.1 ~ 15.3% in driving condition
