Common Issues that Trigger the Check Engine Light


Common Issues that Trigger the Check Engine LightWhen a check engine light illuminates, it doesn't automatically mean that an automotive disaster is nearing. Nonetheless, you'll want to be proactive about getting to the shop for diagnostics so that you don't risk needing 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

This monitors the quantity of incoming air and calculates how much fuel should be injected with it. Fortunately, if this is what's triggering your check engine light, it shouldn't be too costly to address.

Failing Catalytic Converter

On the other hand, this issue can be a rather expensive problem to remedy. Still, it'll need to be taken care of because of the cat's important job, which is to turn carbon monoxide into an emission that is less harmful to the environment.

Faulty Oxygen Sensor

This keeps tabs on the amount of unburned oxygen in your vehicle's exhaust system. Signs of oxygen sensor failure include worsening fuel-efficiency, as well as problems with your catalytic converter.

Bad Battery/Charging System

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

Failing Ignition Coil

Ignition coils play a crucial role in generating the spark required for your engine to come roaring to life on all cylinders. Sometimes, ignition coils will fail because of extreme weather temperatures.

Poorly-Fitting Gas Cap

If your gas cap is missing or fits improperly, then fuel could evaporate before you get the chance to use it, which---as strange as it may seem---can actually cause the light to turn on.
