6 Possible Reasons Your Check Engine Light Is On
If your check engine light turns on, it doesn't necessarily mean that disaster is imminent. Nevertheless, you'll want to be proactive about getting to the shop for diagnostics so that you hopefully don't end up needing expensive repairs that could've been prevented. Here's a look at six common reasons that a check engine light turns on.
Failing Mass Air Flow Sensor
The mass air flow sensor keeps track of the amount of air that is coming in and calculates how much fuel to inject with it. If this is your problem, you'll be fortunate in that it shouldn't be too costly to take care of.
Faulty Catalytic Converter
A failing cat, however, could put a significant dent in your wallet. Still, you'll need to address it because of its important job, which is to make your emissions less polluting.
Failing Oxygen Sensor
Oxygen sensors track how much unburned oxygen is in the exhaust system. Problems with oxygen sensors can cause a drop in gas mileage, as well as issues with the catalytic converter.
Bad Battery/Charging System
When a battery is failing, it can result in low voltage at the computer, which can then trigger the check engine light.
Failing Ignition Coil
Ignition coils play a critical role in creating the electric spark needed to get fired up. Sometimes they fail because of weather extremes.
Loose/Missing Gas Cap
A missing or poorly fitting gas cap could lead to fuel evaporating before you get the opportunity to use it. As strange as it may seem, this is an issue that is a possible check engine light trigger.
