        Result
        Result Action
        NG

        Inspect the ignition system
        OK Replace spark plug
        Note:

        If an ignition coil assembly or spark plug has been struck or dropped, replace it.

    4. B00656HC01
      *a Lock Lever

    INSPECT SPARK PLUG

    Note:

    • Do not use a wire brush for cleaning.

    • Never attempt to adjust the electrode gap of a used spark plug.

    Tip:

    Perform "Inspection After Repair" after replacing a spark plug.



    1. B00689MC34
      *a Body Ground

      Check the electrode.


      1. Using a megohmmeter, measure the insulation resistance.

        Standard Insulation Resistance
        Tester Connection Condition Specified Condition
        Spark plug (terminal part) - Body ground Always 10 MΩ or higher
        Tip:

        • If the result is not as specified, clean the spark plug with a spark plug cleaner and measure the resistance again.

        • If a megohmmeter is not available, perform the following simple inspection instead.

    2. Alternative inspection method.


      1. Start the engine.

        Note:

        Do not perform this step when any of the following DTCs are output; P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308 (Cylinder Misfire Detected)

      2. Quickly accelerate the engine to 4000 rpm 5 times.

        Note:

        Do not perform this step when any of the following DTCs are output; P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308 (Cylinder Misfire Detected)

      3. Remove the spark plug.

      4. Visually check the spark plug.

        Tip:

        If the electrode is dry, the spark plug is functioning properly. If the electrode is damp, proceed to the next step.

    3. Check the spark plug for any damage to its threads and insulator.

      If there is any damage, replace the spark plug.

      Recommended Spark Plug
      Manufacturer Spark Plug Type
      DENSO FK20HBR-J8
    4. B0067K4C01
      *a Spark Plug Electrode Gap
      *b Iridium Tip
      *c Platinum Tip

      Check the spark plug electrode gap.

      Maximum Electrode Gap for Used Spark Plug
      1.0 mm (0.0394 in.)
      Note:

      Never attempt to adjust the electrode gap of a used spark plug.

      If the electrode gap is more than the maximum, replace the spark plug.

      Standard Electrode Gap for New Spark Plug
      0.7 to 0.8 mm (0.0276 to 0.0315 in.)
    5. B0066QX

      Clean the spark plug.

      If the electrode has traces of wet carbon, clean the electrode with a spark plug cleaner and then dry it.

      Standard Air Pressure
      588 kPa (6.0 kgf/cm2, 85 psi)
      Standard Duration
      20 seconds or less
      Tip:

      Only use the spark plug cleaner when the electrode is free of oil. If the electrode has traces of oil, use gasoline to clean off the oil before using the spark plug cleaner.

    6. Install the spark plug.
