Why Is My Check Engine Light On?

It’s never a smart idea to ignore a check engine light because it could mean that your car has some serious fresno automotive repair issues that need to be resolved as soon as possible. Even if you are used to not paying attention to car dash lights, here are some reasons why you should take your check engine light seriously. My Fresno Mazda is fully equipped to deal with all check engine light scenarios, and our professionals can help you figure out what has gone wrong.

Gas Cap Issues

One of the most common reasons that a check engine light turns on is because of a loose gas cap. You should inspect your gas cap and make sure that it isn’t loose, while also checking to make sure that there are no cracks, chips, or tears in the gas cap. If it looks like the gas cap is damaged, you will have to head to an automotive repair shop in Fresno and purchase a replacement gas cap as soon as possible. The gas cap is meant to capture and reuse fuel vapors while also preventing dirt and debris from entering the gas tank.

If your gas cap does not “click in place”, then you should consult with one of our Certified Auto repair Mechnacis in Fresno at Fresno Mazda. If you notice that your gas cap was loose, and make sure that it is now in place – then the check engine light should eventually disappear after you drive for several miles.

Spark Plugs

If your check engine light is on, it might involve an issue with spark plugs. This is a serious repair issue because spark plugs supply the spark that powers your engine. The spark plugs are meant to be very durable, and it’s incredibly important to your ignition system as a whole. A check engine light might even mean that your spark plugs need to be replaced.

Catalytic Converter

There’s another major reason why your check engine light keeps turning on. Your car dash lights may actually be trying to tell you that your catalytic converter isn’t working properly. For those who don’t know, a catalytic converter is the part of your car or truck that is meant to reduce toxic gases and pollutants in the exhaust gas. You can find catalytic converters not only in traditional vehicles, but in electronic generators, forklifts, locomotives, motorcycles, and more.

Your car dash lights might not be the only signal that your catalytic converter isn’t working properly. In fact, it might even be the reason why your car isn’t starting properly. If you choose to ignore your check engine light in this case, a damaged catalytic converter might even cause your car to stall out. If you find that you have a damaged catalytic converter, you should contact Fresno Mazda to assist with this Car repair located in Fresno California near Clovis, Selma, and Madera.
