5 Issues That Could Cause Your Check Engine Light to Turn On

Most of us have had it happen at some point, and when it does, the impulse is to worry that something is terribly wrong. But just because your check engine light has come on, doesn't necessarily mean that you're on the brink of disaster. It could actually be something quite simple and easy to fix. Nonetheless, if your check engine light does illuminate, you'll want to quickly figure out what has caused it to do so. If it's not readily apparent to you, then it's a good idea to get your vehicle into the shop where diagnostic equipment can be used. By acting quickly, it's entirely possible that you'll end up saving yourself a lot of money in repairs. There are numerous reasons why your check engine light might turn on. Here is a look at five of the issues that might cause it to illuminate.

Bad Mass Air Flow Sensor

This monitors the air that is coming in and then makes a determination on how much fuel to inject with it. When this sensor goes haywire, it's entirely possible that the check engine light will come on as a result. Fortunately, this is a rather affordable fix.

Faulty Catalytic Convertor

This is what turns carbon monoxide into an emission that is less harmful. Unfortunately, this issue will cost you quite a bit more than the mass air flow sensor. Nonetheless, it's a part of your car that is important.

Failing Battery or Charging System

Depending on the year that your car was made, this could be the reason that your check engine light has turned on.

Faulty Ignition Coil

This part assists in the creation of the spark that you need to fire up your engine on all cylinders. There are a number of things that can go wrong with ignition coils. One possible reason for the failure is exposure to extremely high temperatures. Or it could just be from standard wear and tear.

Loose or Missing Gas Cap

Yes, it is possible that this is why your check engine light came on. And wouldn't that be a nice bit of relief? A poorly fitting cap can result in the evaporation of gasoline, which your sensors could take as reason enough to illuminate the light.

If your check engine light has come on and you're in need of diagnostics or repair, be sure to get in touch with a reputable shop.
