Spark Plug Insulation Resistance Check

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
  1. Measure the insulation resistance of the spark plug. If the insulation resistance of the spark plug is under the limited value, clean the spark plug (Refer to SPARK PLUG CLEANING ).
  2. After cleaning, measure the insulation resistance again. Replace the plug unless it is within the limited value.

    Limit: Minimum 10 MΩ
