3 Common Reasons the Check Engine Light will Illuminate

There is one thing that happens while driving that can make any car owner's heart sink faster than almost anything else; the illumination of the check engine light. That dreadful little icon representing an engine certainly means that expensive auto repair is in the near future, right? Not necessarily. As long as your bring your vehicle into the shop for proper diagnostics as soon as possible after the light comes on you likely won't have to much to worry about. Many of the most common check engine light problems are quick, inexpensive fixes. But again, the sooner you take care of the problem the better, as it will only get worse, as demonstrated by this first example.

Failed Catalytic Converter

The catalytic converter turns hazardous exhaust fumes into less harmful emissions before they are expelled through the tailpipe. If this important mechanism fails it will trigger the check engine light, resulting in the need for what will likely be an expensive repair. However, there is a good chance that the light was already on due to another, much smaller issue that triggered the light first, such as a sensor that needs replacing. This is why it is important to have the check engine light diagnosed right away!

Mass Air Flow Sensor

One of the most common issues that triggers the check engine light is a problem with the mass air flow sensor. If this sensor becomes dirty or malfunctions in some other way it will be unable to properly calculate the correct amount of air that needs to be mixed with gasoline in order to create the proper air/fuel mixture your vehicle needs to run at peak performance. A bad MAF sensor can drop fuel efficiency by as much as 25 percent! Lucky for you the sensor often just needs to be wiped clean of dust and dirt and reset, a quick and inexpensive procedure.

Loose Gas Cap

Then of course there are those issues that just seem so silly when you find out the actual problem. If you do not tighten the gas cap after filling up or if your gas cap is cracked or otherwise ill-fitting the check engine light will come on. Why? Because it is allowing gasoline vapors to evaporate out of the filler hose. This means you're wasting gasoline that you never even had a chance to use! Again this is a cheap fix, essentially the cost of a new gas cap, if that is indeed the issue!
