Common Reasons a Check Engine Light Illuminates
While the illumination of the check engine light doesn't automatically mean that disaster is looming, it's still best to be safe and get to the shop for diagnostics. Otherwise, you could end up with expensive repairs that could've been nipped in the bud. Here's a look at six common check engine light triggers.
Bad Battery or Charging System
A faulty battery could result in low voltage at the computer, which could consequently trigger the check engine light.
Failing Oxygen Sensor
The oxygen sensor monitors the quantity of unburned oxygen that is in the exhaust system. Your catalytic convertor could actually be negatively impacted by issues with your oxygen sensor.
Faulty Ignition Coil
Your ignition coil plays a central role in creating the spark that your engine requires to get fired up. Sometimes, extreme weather will cause an ignition coil to go kaput.
Failing Mass Air Flow Sensor
Your mass air flow sensor keeps tabs on incoming air and determines the amount of fuel to inject with it. In the event that this is what is triggering your check engine light, you'll be fortunate in that it's a rather budget-friendly issue to address.
Faulty Catalytic Converter
This, however, could cost you a significant chunk of change. Nonetheless, you'll need to get it done because the catalytic converter does the important job of turning carbon monoxide into a less harmful emission.
Loose or Poorly-Fitting Gas Cap
An ill-fitting gas cap can lead to gas evaporating before you have the opportunity to put it to use. It can also---somewhat surprisingly---cause a check engine light to come on.
