What are common reasons a check engine light turns on?
When a check engine light illuminates, it doesn't necessarily mean that an automotive disaster is just around the corner. Nonetheless, it's important to be proactive about getting to the shop so that the issue can be nipped in the bud before it becomes increasingly expensive to fix. Here's a look at six reasons a check engine light comes on.
Faulty Ignition Coil
Your ignition coil works to create the spark necessary for your engine to come roaring to life on all cylinders. Sometimes, ignition coils will fail due to extreme weather conditions.
Bad Battery or Charging System
If a battery is failing, low voltage at the computer could result, which could consequently cause the check engine light to illuminate.
Failing Mass Air Flow Sensor
The mass air flow sensor keeps tabs on incoming air and determines how much fuel to inject with it. If this is what's triggering your check engine light, it shouldn't be too costly to take care of.
Faulty Catalytic Converter
On the other hand, if this is the issue, it could cost a sizeable chunk of change to address. Still, it's something that should be remedied quickly because of the catalytic converter's important role, which is to turn carbon monoxide into an emission that is less impactful on the environment.
Failing Oxygen Sensor
The oxygen sensor monitors the quantity of unburned oxygen in your exhaust system. Trouble with it could lead to a reduction in gas mileage, as well as problems with your catalytic convertor.
Improperly-Fitting Gas Cap
When a gas cap is loose or ill-fitting, gas can evaporate before you get the chance to use it. As strange as it may seem, this could actually trigger the check engine light.
