General Information: DTC Detecting Condition
DTC DETECTING CONDITION
| Item | Detecting Condition | Possible Cause | |
|---|---|---|---|
| DTC Strategy | * Determine if a multiple cylinder misfire or a cylinder specific misfire is occurring by monitoring crankshaft acceleration. | * Faulty Spark plugs * Faulty Spark plug cables * Air Leakage * Belt deflection and Air gap of CKPS * Incorrect timing * Faulty injector * Improper fuel pressure * Improper engine compression |
|
| Enable Condition | No disabling faults present / no disabiling Active Faults * P0340 / P0341 / P0118 / P0117 / P0115 / P0336 / P0335 / P1295 / P0103 / P0102 / 0108 / P0107 / P0106 / P0501 * Engine speed between 550 and 5800 RPM * System voltage between 9 and 18 volts v |
||
| Threshold value | Case 1 | * Individual cylinder misfire detection | |
| Case 2 | * Emissions damaging - 18 times in 600 ignitions (In case that the misfire affects more than 1.5 times than FTP emissins) | ||
| Case 3 | * Catalyst damaging - 95 times in 600 ignitions at idle ( It is going to be changeable according to the load or the temperature which is not in the range where it does not melt catalyst) | ||
| Diagnosis Time | * Continuous | ||
| MIL On Condition | * 2 driving cycles | ||
