Note: The resistance value of a good spark plug is between 5 ohms. If the reading is outside of the normal range, then the spark plug is most likely damaged and needs to be replaced. If the reading on the multimeter is within the normal range, then the spark plug is working properly.Touch the probes of the multimeter to the metal tip of the spark plug and to the metal sleeve that goes around it.Set the multimeter to the “resistance” setting.Once the spark plug is clean, reattach it to the multimeter.Use a wire brush to clean off any dirt or debris that may be on the spark plug.First, remove the spark plug from the engine.Step by Step Procedure to test spark plug with a multimeter: If you suspect that your spark plug may be faulty, you can use a multimeter to test it and see if it is indeed damaged.
