Common Reasons a Check Engine Light Turns On
While the illumination of the check engine light doesn't automatically mean that a disaster is looming, it's still best to be proactive about getting to the shop for diagnostics. In doing so, you'll help to make sure that you don't end up spending an exorbitant sum on a problem that could have been nipped in the bud. Here's a look at six common causes of a check engine light coming on.
Failing Ignition Coil
Ignition coils are critical to generating the spark needed to get your engine fully fired up. Sometimes they'll go haywire due to extreme weather conditions.
Bad Battery or Charging System
A faulty battery can result in low voltage at the computer, which can then trigger your check engine light.
Faulty Mass Air Flow Sensor
The mass air flow sensor tracks the quantity of incoming air and calculates the amount of fuel to inject with it.
Failing Catalytic Converter
This is a rather costly issue to take care of, but is one that needs to be addressed. The catalytic converter has an important job, which is to turn carbon monoxide into an emission that is less environmentally harmful.
Faulty Oxygen Sensor
Oxygen sensors keep tabs on the amount of unburned oxygen that is present in your exhaust system. When there are issues with an oxygen sensor, you could see a decrease in fuel-efficiency, as well as problems with your catalytic converter.
Poorly-Fitting Gas Cap
If your gas cap is missing or ill-fitting, then fuel could evaporate before you get the opportunity to put it use---and your check engine light might even turn on.
