On-vehicle Inspection

  1. Warm up the engine and idle it.
  2. Listen for operation sound of each fuel injector with a screwdriver or a soundscope.
    • If no sound is heard, perform the "Fuel Injector Resistance Inspection".
    NOTE:
    • The best way to judge the performance of a fuel injector is to compare its sound with the sound of other fuel injectors.
