3 Common Culprits Behind an Illuminated Check Engine Light

We’ve all been there. When any indicator suddenly pops up on the dashboard, you immediately start to worry. This is especially true when the check engine light illuminates. You might be thinking, What’s wrong with my car? or Will this be an expensive fix?

Luckily, the experts at Wally’s Auto Care in Ammon, Idaho, are here to help. If your check engine light is on, bring your car to our shop for a check engine light diagnostics test.

Here are three common reasons your check engine light is on.

A Loose Gas Cap

Accidentally forgetting to tighten your gas cap is a common occurrence. It might also be the reason why your check engine light is on. To fix the problem, simply tighten the cap. If your check engine light switches off, you’re good to go!

Oxygen Sensor Needs Replacing

This is another common culprit behind an illuminated check engine light. Oxygen sensors (O2 sensors) help to ensure your car is burning the proper amount of fuel to operate at peak performance. Over time, your car’s sensors can get coated with ash, which will drastically reduce their ability to function correctly. Not only will this trigger your check engine light, but it can also damage your AC system.

Faulty Catalytic Converter

Catalytic converters are critical components of your car that regulate the emissions your car releases, including carbon monoxide. Most catalytic converters will last as long as your car does. However, sometimes they can fail.

If your catalytic converters are going bad, you’ll experience strange odors, decreased performance, and less fuel efficiency. It’s best to get them fixed as soon as possible.
