| DTC Strategy |
|
- Poor connector connection
- Incorrect Valve Timing
- Uneven Compression
- Air Leakage
- Improper Fuel Pressure or Dirty Fuel
- Blocked/Leaking Injectors
- Leakage between cooling system and system
- Faulty ignition system
- Faulty MPI injector

| Enable Condition |
- Engine speed is between 600 and 6700 RPM
- Engine load is between 6.7 and 22.8% (depending on engine speed)
- Atmospheric pressure higher than 75 kPa
- Engine load variation less than 0 - 48%/s (depending on engine load)
- Throttle track change less than 2 - 80% (depending on throttle track)
- Engine coolant temperature above -7°C (19.4°F), If the coolant temperature at engine start is below -7°C (19.4° F), over 20°C (68°F)
