5 Easy Steps to Reset Your Check Engine Light

We’ve all seen the check engine light come on in our vehicles, and most of us have seen it more than once.

Sometimes it means that something is seriously wrong with your car, but most of the time it is a minor fix that you can do yourself.

Luckily, many times you won’t even have to take your automobile into the mechanic shop if you have the right equipment to diagnose the problem yourself.

With this age of information being readily available to us, just about anyone can diagnose the reason why their check engine light is on just by doing a quick Google search. Of course, it will help speed up the process if you have some knowledge about vehicles, but sometimes that’s not even necessary.

The problem may be as simple as tightening the gas cap.

So before you spend hundreds, or even thousands, of dollars at a mechanic shop, follow these steps to try to diagnose the problem yourself.

You will be shocked at how much time and money you could potentially save!

Step 1: Buy an OBD Scanner or Reader

OBD is short for “on board diagnostics”.

You can find these handy tools at Amazon.com or just about any other place that has an automotive department.

Expect to pay around $50-$60 for an OBD reader, but keep in mind that this is a one-time cost.

If you take your vehicle to the mechanic every time your check engine light comes on, you will likely pay at least $100 for every visit.

A little bit now on how an OBD reader works.

Your car has a computer in it that receives signals from a variety of automotive systems. If something is not working properly in your vehicle, then the system will send a signal to the computer, and the check engine light turns on so you know something is wrong.

When you plug in your OBD reader, it will display the code that shows the faulty part to help you diagnose the issue.

Step 2: Hook it Up to Your Car and Scan for Codes

When you have your OBD reader, look under your driver’s side dashboard and you’ll see a port that the reader can fit into. Make sure that your car is NOT running while you perform this step.

Once you have the OBD reader connected, turn the key to the “on” position, but don’t turn the engine on.

Press the scan button on your OBD reader and give it a few seconds or a couple minutes to search for codes.

Once it finds the problem, it will either give you a single code or a list of codes.

Write that code number down and move on to the next step.

Step 3: Search Your Code Online

While the code you receive may not mean anything to you right away, you will soon be very informed about what it means.

Simply enter that code into Google or another search engine and see what you can find.

There are tons of automotive forums that will help you diagnose just about any code that your OBD reader displays.

If for some reason your code isn’t pulling up any results in the search engine, try to also include the make and model of your vehicle.

Most of the time, several other people have seen the same code pop up on their vehicle. You can read step-by-step instructions online without having to ask a mechanic! And the best part is you don’t even have to be an expert in many cases. However, if you have no idea what you are doing, then it’s best to ask someone who has a little bit of knowledge with working on cars.

Step 4: Find the Part, Remove and Replace it

Once you know what needs to happen, now it’s time to take action and replace the part.

Online forums should tell you exactly where to find the faulty part on your vehicle, but you can also resort to your vehicle’s owner’s manual for help.

When you find the part, you can simply order it online or go to a store that sells auto parts to get it replaced.

Many times you will find that the part is very inexpensive and only takes a few minutes of your time to replace it.

Step 5: Erase the Code from the Scanner

Once the part is replaced, plug the OBD reader back in and press and hold the “erase” button.

Assuming there are no other problems, the check engine light on your vehicle should now be gone.

Conclusion

As you can see, it doesn’t take too much time or effort to reset the check engine light on your vehicle.

The most important thing to remember is to not bite off more than you can chew.

If you have no experience at all with working on cars and aren’t confident with working on them, you can still save money by purchasing an OBD reader.

In addition to the money you would save, the whole process that we outlined in this article could take as little as 30 minutes to an hour.
