6 Problems that Can Trigger a Check Engine Light


6 Problems that Can Trigger a Check Engine LightWhen a check engine light comes on, it doesn't necessarily mean that an automotive disaster is just around the corner. Nonetheless, it'll be best to soon get to the shop for diagnostics so that you don't risk spending an excessive amount of money on repairs that could've been nipped in the bud. Here's a look at six common reasons a check engine light turns on.

Failing Ignition Coil

Ignition coils play a critical role in the creation of the spark required for your engine to fire up on all cylinders. They'll sometimes go bad due to extreme weather conditions.

Faulty Mass Air Flow Sensor

This tracks incoming air and calculates the amount of fuel that should be injected with it. If this is what's triggering your check engine light, you'll be fortunate in that it won't cost too much to be addressed.

Failing Catalytic Converter

This, however, can be rather spendy to take care of. Nevertheless, it'll have to be remedied because of the important job of the catalytic converter, which is to turn carbon monoxide into an emission that isn't as environmentally damaging.

Faulty Oxygen Sensor

Your oxygen sensor keeps tabs on the amount of unburned oxygen in your exhaust system. Trouble with it can result in worsening gas mileage, as well as problems with your catalytic converter.

Bad Battery or Charging System

A failing battery can result in low voltage at the computer, which could consequently trigger the check engine light.

Poorly-Fitting Gas Cap

This might seem strange, but it's true. A loose or ill-fitting gas cap can lead to fuel evaporating before you have the opportunity to use it---and might also actually cause your check engine light to illuminate.
