What's causing my check engine light to illuminate?

What's causing my check engine light to illuminate?When a check engine light illuminates, it doesn't automatically signify that an automotive disaster is looming. However, you'll still want to get to the shop for diagnostics so that you don't risk needing major repairs that could've been prevented. Here's a look at six common check engine light triggers.

Faulty Mass Air Flow Sensor

This keeps tabs on the quantity of air that is entering and determines how much fuel to inject with it. If this is what's triggering your check engine light, you'll be fortunate in that it shouldn't be too expensive to address.

Failing Catalytic Converter

A bad catalytic converter, on the other hand, can cost you a decent chunk of change. Nevertheless, it'll need to be addressed because of the cat's important role, which is to make emissions less damaging to the environment.

Faulty Oxygen Sensor

Oxygen sensors monitor the amount of unburned oxygen within the exhaust system. An issue with an oxygen sensor can result in reduced fuel-efficiency, along with catalytic converter problems.

Bad Battery/Charging System

A failing battery can lead to low voltage at the computer, which can consequently cause the check engine light to illuminate.

Failing Ignition Coil

Ignition coils are central to generating the electric spark required to get a vehicle started up. Extreme weather conditions sometimes cause their failure.

Loose/Missing Gas Cap

A missing or ill-fitting gas cap can result in fuel evaporating before you get the chance to use it. While it might seem strange, this can actually trigger the check engine light.

If you're in need of auto repair, be sure to visit a reputable mechanic. For check engine light diagnostics and repair in Kingman, AZ, the experts to contact are with Advanced Transmission. Feel free to visit Advanced Transmission today for any of your repair or maintenance needs!
