There are many sensors around the engine, such as the oxygen sensor, air flow sensor, intake air temperature sensor, coolant temperature sensor, and camshaft position sensor. Spark plugs need to be replaced regularly. Long-term use of spark plugs will cause the electrode gap to widen, which can affect the spark plug's ignition.
