Why is my Check Engine Light on?
When your check engine light comes on in your vehicle, we know it is usually accompanied with a stressed or nervous feeling and a pit in your stomach. What could be wrong? How much is this going to cost? Am I okay to drive with the light on? We know a million questions are flooding your mind and so we created this post to hopefully shed some light on your check engine light on your vehicle. Keep reading to check out the top five reasons your check engine light may be on.
Quite simply, the check engine light is a signal from the car’s engine computer that something is wrong. Check engine lights come in orange, yellow or amber color depending on the manufacturer. If the light begins flashing, it indicates a more serious problem such as a misfire that can quickly overheat the catalytic converter. Here are the top five reasons your check engine light may be on.
Oxygen Sensor Needs Replacing:
Your oxygen sensor measures the amount of unburned oxygen in your vehicle’s exhaust system. If you don’t have it replaced your engine will burn more fuel then needed, you will have a loss in fuel economy, and faulty sensors can cause damage to your spark plugs and catalytic converter.
Gas Cap is Loose, Damaged or Missing:
Your gas cap seals the fuel system and helps maintain pressure within the fuel tank. It also prevents gasoline fumes from being released into the atmosphere while you aren’t driving your car. If you don’t replace it you can lose fuel through evaporation.
Catalytic Converter Needs Replacing:
Your catalytic converter helps protect the environment by converting harmful carbon monoxide into carbon dioxide. If you don’t replace it, you vehicle will not pass an emissions test, you will experience reduced performance and fuel economy and your vehicle may run at a higher temperature.
Mass Airflow Sensor Needs Replacing:
Your mass airflow sensor measures the amount of air entering the engine to determine how much fuel is needed to run your engine efficiently. If you don’t replace it, faulty sensors can cause damage to spark plugs, O2 sensors or catalytic converter and you will experience reduced performance and fuel economy.
Spark Plugs or Plug Wires Need Replacing:
Spark plugs ignite the fuel/air mixture in the combustion chamber of your vehicle. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If you don’t replace it you will experience poor performance and reduced fuel economy and worn plugs can cause a clogged catalytic converter or damage to ignition coils and O2 sensors.
