Why Is My Check Engine Light On?

Fortunately for drivers, many vehicles, especially newer models, are exceedingly self-aware. Gauges and computers measure the vehicle’s performance and can notify you if there is an issue. One thing that many drivers have experienced is a flashing check engine light.

Often appearing without warning, a check engine light coming on indicates that something may be wrong with your vehicle. But what could it be? It’s very important to get your vehicle checked if the light comes on, but below are a few reasons your vehicle may be notifying you.

Loose Gas Cap: A loose gas cap is a common cause of a check engine light. It is very important to keep the cap closed tightly, which is why it will set off your check engine light if it is not. Luckily for the driver, it is a much cheaper and easier fix than the rest of the items on the list.

Malfunctioning Spark Plugs: The spark plugs are the ignition source of your engine. If they are faulty or malfunctioning, you may have trouble getting your engine to “catch” and get your vehicle started. These parts do wear out over time, so it is important to get them changed for the performance of your vehicle.

Oxygen Sensor Issue: The O2 sensor determines the amount of oxygen in your vehicle’s fuel, which is used to determine how a vehicle burns. If this is malfunctioning, your vehicle will still work, but there may be long-term issues and a drop in fuel efficiency.  

Most drivers experience a check engine light at some point in their lives. While it could be a simple loose gas cap, it’s important to get your vehicle checked as the problem could be much more severe.
