Something is wrong, but that warning light can stand for lots of different possible problems, some more serious than others. Fortunately, the Patty Peck Honda service center is here to help! If you’re wondering why your Honda’s check engine light is on, we’ll figure out the problem fast, so you can get back on the road as soon as possible. And to give our readers a little extra peace of mind, here’s what to expect from a few of the most common check engine light causes.

4 Common Reasons You Might See A Check Engine Light

Gas Cap Is Loose Or Damaged

If your check engine light comes on a few minutes after you’ve filled up on gas, check whether the gas cap is loose. If the gas cap isn’t properly shut, fuel vapors can leak out and upset the balance of the whole fuel system. This is the best-case scenario for a check engine light – even if the gas cap is damaged or totally missing, it’ll only cost a few dollars to replace.

A Sensor Is Malfunctioning

Your Honda’s engine contains several different types of sensors that keep everything running smoothly. Oxygen sensors help the car monitor how much fuel is being burned, and the mass airflow sensor helps balance the mixture of air and fuel going into the engine. If one of these sensors breaks, it’ll turn your check engine light on. Driving with a broken sensor will sink your gas mileage and damage other parts of your engine over time, so it’s important to get it replaced right away!

Spark Plugs Need Replacing

Spark plugs and wires wear out over time, and they’ll eventually need to be replaced as part of the normal Honda maintenance schedule. If you’re behind on maintenance and your check engine light comes on, a worn out spark plug might be to blame.

Catalytic Converter Issues

This is the worst problem on the list – a broken catalytic converter is expensive to replace. Fortunately, it’s not likely to break unless you’ve been ignoring one of the other problems further up the list. That’s why it’s so important to get your check engine warning light diagnosed right away! Don’t hesitate to schedule a service appointment at your earliest convenience as soon as you see it!
