6 Common Check Engine Light Triggers
When the check engine light turns on, it doesn't necessarily mean that you're on the cusp of an automotive disaster. Still, you'll want to be proactive about getting to the shop so that you don't end up needing extensive repairs that could've been prevented. Here's a look at six common reasons that a check engine light turns on.
Faulty Mass Air Flow Sensor
Your air flow sensor monitors incoming air and then calculates how much fuel should be injected with it. If this is what's triggering you check engine light, it shouldn't cost you too much to address it.
Failing Catalytic Converter
A failing catalytic converter, however, can be a rather costly issue. But you'll need to take care of it because of the cat's important job, which is to turn carbon monoxide into an emission that is less harmful to the surrounding environment.
Faulty Oxygen Sensor
Your oxygen sensor keeps tabs on the amount of unburned oxygen that's in your exhaust system. Problems with an oxygen sensor can cause a reduction in gas mileage, as well as issues with the catalytic converter.
Failing Ignition Coil
Ignition coils play an important role in creating the spark that's needed to bring your engine roaring to life on all cylinders. Extreme weather will sometimes cause the failure of ignition coils.
Bad Battery/Charging System
A failing battery can result in low voltage at the computer, which could consequently trigger the check engine light.
Loose/Missing Gas Cap
It might seem strange that this could trigger the check engine light, but it does happen. A poorly fitting gas cap can result in gas evaporating before you get the opportunity to put it to use.
