The check engine light is one of the most common warning lights that you can see on your car’s dashboard. It can be illuminating for a variety of reasons, and it’s imperative to know how to check the engine on your car to determine the cause. In this post, we’ll go over the steps on how to check engine on car, as well as some of the most common reasons why the light may be on.
Step 1: Gather your tools
Before you start, you’ll need to gather a few tools. These include:

Once you’ve found the OBD-II port, connect the code reader. The code reader will retrieve the trouble code from the car’s computer.

The trouble code will be a five-digit number. The first digit indicates the type of problem, the second digit indicates the system that is affected, and the third and fourth digits indicate the specific problem.

Once you have the trouble code, you can use it to diagnose the problem. You can consult a repair manual or online resource to find out what the code means and how to fix it.
Step 6: Repair the problem
Once you’ve diagnosed the problem, you can repair it. This may involve replacing a faulty sensor, cleaning a dirty part, or performing a more complex repair.
Step 7: Clear the trouble code
Once you’ve fixed the problem, you need to clear the trouble code from the car’s computer. You can do this using the code reader.
