DTC Information: 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 rotation speed
  • 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
