5 Common Reasons that Your Check Engine Light Will Turn On
When the check engine light comes on, the tendency is to fear that something disastrous is about to happen. And while it certainly could be an indication of a significant issue, that isn't necessarily the case. The check engine light will also come on because of causes that are less threatening to your car, and to your wallet. It could even have turned on because of something as harmless as a loose gas cap. Nonetheless, you want to play it safe and be sure you quickly determine what is going on with your engine. By getting into a reputable auto shop, a service tech will be able to quickly diagnose what the issue is, and then get it remedied. There are a number of reasons why your check engine could come on. Here are five of those reasons:
Failing Mass Air Flow Sensor
The mass air flow sensor monitors incoming air and then determines how much fuel to inject with it to help make sure that your engine is performing highly. If this sensor is failing, that can be a reason that your check engine light is coming on. This a very affordable thing to fix and you'll want to get it done quickly to maintain good gas mileage.
Bad Catalytic Converter
The catalytic converter's job is to convert carbon monoxide into a less harmful emission. Replacing a catalytic converter can be somewhat costly, but it's a necessary component of your car. If your sensors detect a problem with your catalytic converter, this could be the cause of the check engine light coming on.
Dying Battery or Charging System
Depending on how new a model your vehicle is, the battery or charging system could also be what is causing alarm.
Failing Ignition Coil
Your ignition coil helps to provide the spark that is necessary for your engine to fire up on all cylinders. The coil works to increase the voltage that is produced by your 12 volt battery. It can go bad because of a number of reasons. For one, it could fail because of exposure to extremely high temperatures. Regardless, the coil will eventually need to be replaced as a result of standard wear and tear.
Loose Gas Cap
Something as simple as a loose gas cap can be the cause, and what a relief it would be for that to be the only reason your check engine light has illuminated. If gas is evaporating through a poorly-fitting cap, your sensors might see this as a reason to turn on the check engine light.
