Typically, when we talk about “the light,” it’s a good thing, but when you put the words “check engine” in front of it, you’re often talking about the bane of our existence. If you’re shopping on AutoBidMaster for a salvage car, you may find it comes with a check-engine light already on (as many used cars do), but you don’t have to worry.

A check engine light should never be ignored, but sometimes the solution is easier than you think. Here are 5 common check engine light issues and how to fix them, quick.

Gas Cap

This one is incredibly common. Think about it – you take your gas cap off just to put it back on multiple times a week. That adds up over time, and the threads wear out. Here’s the thing though – if your gas cap is loose, that not only contributes to worsening gas mileage as fuel evaporates, but it can trigger your check engine light as well. The reason being that your car’s First, make sure it’s tightened all the way. If that doesn’t fix it and the threads look worn, you can get a replacement for a few bucks and see if it fixes the check engine light.

Oil Change

We’re all busy, and changing your oil is probably the last thing you want to do with your day. The bad news is: you gotta. Just do it. Not only do check engine lights come on at regular intervals to indicate the necessity for an oil change, but ignoring an oil change can lead to catastrophic issues.

Check your car’s manual for the recommended oil change intervals and follow them, seriously. It’s the easiest way to prevent serious damage to your vehicle. And to avoid check engine lights driving you crazy.

O2 sensor

Your O2 sensors monitor the amount of unburned oxygen coming out of your exhaust, and a faulty one can trigger your car’s check engine light. While this isn’t catastrophic, ignoring the issue for a prolonged period of time can cause decreased fuel efficiency and lead to issues with catalytic converters, as the car adjusts fuel mixtures according to information from your O2 sensors.

Old spark plugs

Spark plugs are what cause the initial spark in your engine – hence the name spark plugs. If your spark plugs are old or dirty (aka ‘fouled’), this can cause your car to misfire or to rev inconsistently when accelerating. New spark plugs can go well over 100,000 miles, but older ones need to be replaced every 30,000-60,000 miles. A bad plug can also cause the light to turn on, and replacing them yourself is pretty easy. They’re cheap, too.
