What are common check engine light triggers?
When you see your check engine light turn on, the impulse might be to worry that you're on the verge of major engine trouble. While this isn't necessarily the case, you'll still want to get to the shop for diagnostics so that you don't risk needing expensive repairs that could've been prevented. Here's a look at six common reasons that a check engine light turns on.
Failing Ignition Coil
Ignition coils play a critical role in the ability of vehicles to get fired up on all cylinders. Sometimes they fail due to extreme weather conditions.
Bad Battery or Charging System
When a battery goes bad, it can cause low voltage at the computer, which can consequently trigger your check engine light.
Failing Mass Air Flow Sensor
This keeps tabs on the amount of incoming air and calculates how much fuel to inject with it. If this is what is causing your light to illuminate, it shouldn't cost an exorbitant amount to get it taken care of.
Bad Catalytic Converter
A failing catalytic converter, however could hit you hard in the pocketbook. Nonetheless it'll need to be done because of the catalytic converter's important job, which is to turn carbon monoxide into an emission that is less harmful to the environment.
Faulty Oxygen Sensor
Oxygen sensors monitor the quantity of unburned oxygen in the exhaust system. When they start to go haywire, you could see a drop in gas mileage, as well as issues with your catalytic converter.
Loose/Missing Gas Cap
If a gas cap is missing or poorly-fitting, then fuel can evaporate before you get the opportunity to use it. Although it might seem strange, this is an issue that can actually trigger you check engine light.
