3 Common Check Engine Light Causes

Is This What’s Wrong With Your Car?

The check engine light is a common concern for drivers. After all, your vehicle seems to be fine one moment and then suddenly, the light is on! What happened since the last time you drove? Motorcars international in Smyrna, Georgia has the answers. We help drivers with check engine light problems, and in our years of experience, we’ve seen every possible cause. To help our customers better understand this warning signal, we have compiled a list of the most common triggers. One of these problems could be the reason that your check engine light is on, but there are countless contributors to your vehicle’s overall health. To get an accurate idea of what’s wrong with your car, be sure to visit our shop for diagnosis.

Loose Gas Cap

If you don’t replace the gas cap after refueling, your check engine light may illuminate. Be sure to check that the cap is tightened correctly, then continue driving for a few miles to allow the sensors to reset. If the light stays on, there is likely another issue going on.

Replacing a lost gas cap is easy! Stop by a local auto parts store to find a suitable lid for your specific vehicle.

Failing Spark Plugs

The spark plugs ignite the fuel and air mixture in the engine to start combustion and power the vehicle. These tiny components have a big job to do and are very susceptible to wear over the lifespan of your car. They’ll likely need to be swapped out to prevent engine misfire.

Worn coils and spark plugs exhibit similar warning signs of failure. Replace both to confidently rule them out as a cause of the check engine light. You could save yourself the trouble of replacing one or the other shortly after.

Oxygen Sensors

Oxygen sensors measure the amount of unburned oxygen in the exhaust system. They send data to a computer that controls the amount of air that enters the fuel for maximum efficiency. Like spark plugs, these tiny parts are easily susceptible to failure over time after years of use. They could be the trigger for your check engine light.

A car with faulty oxygen sensors can still operate, but you may be burning more fuel than usual.

Is one of these parts the reason for your vehicle’s check engine light? These are simple fixes that the team at Motorcars International in Smyrna, Georgia can easily perform. It’s best to visit our experts for final diagnosis to ensure something more serious isn’t going on under the hood.
