Reasons for Your Check Engine Light to Turn On
Have you ever been in the situation when driving, all of a sudden your Check Engine light comes on? Could this issue be caused by a major problem or is it something minor? Here are five different reasons as to why your check engine light may be on and what you can do to fix the issue.
Oxygen Sensor Needs Replacing:
The oxygen sensor measures the amount of unburned oxygen in the vehicle’s exhaust system. If not replaced, the engine will burn more fuel than needed. The faulty sensor can also cause damage to your spark plug and catalytic converter.
Loose or missing Gas cap:
The gas cap seals the fuel system and helps maintain the pressure in the fuel tank. The gas cap also prevents gasoline fumes from being released into the atmosphere while you aren’t driving. If not replaced, fuel can be lost due to evaporation which means more trips to the gas station.
Replace the Catalytic Converter:
The Catalytic Converter helps protect converts harmful carbon monoxide into carbon dioxide. Damage can be caused due to lack of basic maintenance. If not replaced your vehicle will not pass an emissions test and the car may run at a higher temperature.
Replace the Mass Airflow Sensor:
The Mass Air Flow Sensor measures the amount of air entering the engine to determine how much fuel is needed to run the engine efficiently. If not replaced, a faulty sensor can cause damage to the spark plug, O2 Sensor, or catalytic converter.
Replace Spark Plug or Plug Wires:
The spark plug ignites the air/fuel mixture in the combustion chamber of the car. The plug wires carry the spark from the ignition coil to the spark plug. If not replaced, damage to the O2 sensor or the catalytic converter.
