  • Detachment or other problems with the engine oil dipstick, filler cap, ventilation hose or other components may cause the engine to run improperly.
  • Air suction caused by disconnections, looseness or cracks in any part of the air induction system between the throttle body assembly and cylinder head sub-assembly will cause engine failure or engine malfunctions.

If any defects are found, replace parts as necessary.

2. INSPECT EVAPORATIVE EMISSION CONTROL SYSTEM

CAUTION:

  • When working near the engine room while the engine has started or the power source mode is ignition switch to ON (IG), do not touch the fan and generator V belt or rotating components such as the fan, etc.
  • Touching the fan and generator V belt or rotating components such as the fan, etc. could result in your hand or clothing getting caught and pulled in.
