3 Reasons Your Check Engine Light Is On, Geneseo, New York

It’s a scenario most people dread: You’re driving along and, suddenly, you notice the check engine light has illuminated on the dashboard. Unfortunately, that little signal merely indicates something is wrong, but doesn’t give any clues beyond that. Do you need to go to an auto mechanic or not? Read on for three common culprits behind this situation.

Why Is the Check Engine Light On?

1. The Catalytic Converter Needs Repairs

This crucial component of your vehicle turns toxic carbon monoxide into carbon dioxide, which is safer for the environment. With its help, the car passes state emissions tests, stays cool, and uses less fuel. Your auto mechanic should check it each time you go in for a tuneup, but if you haven’t been in a while, it might be broken.

2. The Gas Cap Is Looseauto mechanic

An illuminated check engine light doesn’t necessarily mean something serious is wrong. This will activate if you didn’t tighten the gas cap all the way or if the plastic part is broken. If you recently visited the pump, you may want to check this first before running to the auto mechanic for help.

3. You Need a New O2 Sensor

This is the component that ensures your engine doesn’t use too much fuel by measuring the amount of unburnt oxygen in the gas. Without it, you’ll wind up spending way more at the pump. If you don’t have someone look at it right away and make the necessary repairs, other parts of your vehicle, like the spark plugs, will get damaged also.
