Common Check Engine Light Triggers
When a check engine light illuminates, it doesn't automatically mean that an automotive disaster is just around the corner. Nonetheless, it's best to get your car to the shop for diagnostics so that you hopefully don't end up with expensive repairs that could've been nipped in the bud. Here's a look at six common reasons that a check engine light comes on.
Faulty Mass Air Flow Sensor
You mass air flow sensor monitors the quantity of incoming air and determines the amount of fuel to inject with it. If this is triggering your light, you'll be happy to hear that it's an issue that shouldn't be too expensive to address.
Failing Catalytic Converter
This, on the other hand, could cost a significant chunk of change to take care of. Regardless, it'll need to be addressed because of the important job of the cat, which is to turn carbon monoxide into an emission that isn't as damaging to the environment.
Faulty Oxygen Sensor
Your oxygen sensor keeps tabs on the amount of unburned oxygen in your exhaust system. Issues with your oxygen sensor can lead to a decrease in fuel-efficiency, as well as trouble with the catalytic converter.
Bad Battery or Charging System
A faulty battery can cause low voltage at the computer, which can then trigger you check engine light.
Failing Ignition Coil
Healthy ignition coils are critical to your vehicle's ability to fire up on all cylinders. They can be weather sensitive and will sometimes fail due to extreme heat or cold.
Loose/Missing Gas Cap
An ill-fitting gas cap can lead to fuel evaporating before you even get the chance to put it to use. While it might seem odd, this is actually an issue that could potentially cause your check engine light to turn on.
