Why Is My Check Engine Light On?

It might seem like the end of the world when your check engine light comes on, but it might not be as bad as you think. The light is just an indicator that a problem within your engine needs to be fixed. So whenever you notice the light on, contact our auto repair shop to have the problem properly diagnosed using the right computer equipment. At Open Road Automotive & Tire, you can trust us to pinpoint the problem and resolve the issue for you.  

 

Here are the four most common reasons behind a lit-up check engine light:

Faulty Catalytic Converter

The catalytic converter helps minimize harmful emissions by converting carbon monoxide and other toxic chemical vapors into less harmful emissions. This part usually doesn't fail unless something else has previously broken, such as spark plugs or an airflow sensor. This domino effect is why you should get your car to an auto repair as soon as the light comes on to prevent the problem from escalating. 

 

Broken Gas Cap

When your light comes on, the best thing you can hope for is a damaged gas cap. This is the easiest and quickest fix. Gas will evaporate through the opening of an ill-fitting fuel cap causing the light to come on. To avoid the unnecessary cost of a test, always be sure to tighten and secure your lid every time you fill up your gas tank.

 

Damaged Ignition Coil

A bad coil suggests that your car won't be able to provide the spark needed to make your combustion engine fire up. The coil extends the voltage produced by the battery and can go stale for many reasons. An instance when this can happen is when a vehicle operates in extremely high temperatures. 

 

Corrupted Mass Air Flow Sensor

The airflow sensor monitors incoming air and calculates how much gasoline to inject with it to ensure that the engine runs smoothly. If the car's sensor system detects this malfunctioning, the check engine light will illuminate. The process to fix the mass airflow sensor is simpler, but it should be taken care of as soon as possible.
