6 Reasons Your Check Engine Light Will Turn On
An illuminated check engine light can be worrisome. Fortunately, modernized auto repair shops have technologically advanced diagnostic equipment that can get the problem identified and addressed as quickly as possible, so hopefully you'll be back on the road with little delay. There are a number of issues that can cause a check engine light to come on. Here is a look at six common causes of a check engine light turning on.
Faulty Mass Air Flow Sensor
This monitors incoming air and calculates how much fuel to inject with it. If this is what is causing your check engine light to come on, you're not in too bad of shape. This is a relatively inexpensive issue to address.
Bad Catalytic Convertor
This is what turns carbon monoxide into an emission that is less harmful to the environment. Unfortunately, if this is your problem, it could well make a more significant dent in your pocketbook to get it taken care of. Nonetheless, it's an important part of your vehicle and should be addressed quickly.
Failing Oxygen Sensor
This is what keeps track of the amount of unburned oxygen in your exhaust system. Problems with your oxygen sensor can result in reduced fuel-efficiency, as well as issues with your catalytic convertor.
Faulty Ignition Coil
This plays a major role in generating the spark that is needed for your engine to fire up on all cylinders. Ignition coils can go awry from extreme weather temperatures, or also just from regular wear and tear. Whatever the cause, if it is failing, it can be the reason your check engine light illuminates.
Bad Battery or Charging System
Depending on the particular year that your car was manufactured, this could be the reason that the light comes on.
Poorly-Fitting Gas Cap
If your gas cap doesn't fit snugly, then gas can evaporate before it gets used, which can actually trigger the check engine light.
