Are you wondering how to figure out the reason behind your check engine light being on? It can be a nerve-wracking experience, but fear not! In this guide, we will walk you through the steps to diagnose the issue and understand what’s causing the check engine light to illuminate.
When the check engine light comes on, it’s easy to assume it will lead to an expensive repair. However, understanding the problem can often lead to a simple solution. By following the steps outlined in this video, you can save money on basic repairs and even have an informed discussion with your mechanic.
Using an OBD2 Scanner
The video demonstrates the use of a basic OBD2 scanner to read the codes causing the check engine light to turn on. These scanners are affordable and readily available online. By connecting the scanner to the OBD2 port, which is located under the dashboard in most vehicles, you can retrieve the diagnostic trouble codes (DTC) triggering the light.
Interpreting the Codes
Once the scanner reads the codes, it’s crucial to research the specific DTC associated with your vehicle’s make and model. Understanding the code will provide insights into the underlying issue, allowing you to assess whether it’s something you can address yourself or if it requires professional attention.
Addressing the Issue
With the identified code in hand, the video emphasizes the importance of researching the problem online. It provides a practical example of a camshaft position sensor issue and explains how, in many cases, the solution can be relatively simple and cost-effective.
After addressing the underlying problem, the video explains the process of clearing the diagnostic trouble codes. It’s also highlighted that the readiness status for emission tests is essential and can be easily monitored using the OBD2 scanner, ensuring your vehicle complies with emission standards.
Finally, the video offers additional tips, including the importance of researching codes independently, even if you don’t plan on fixing the issue yourself. It stresses how gaining knowledge about potential problems can save you money and ensure fair treatment when seeking professional help.
By following these steps, you can demystify the check engine light and take informed actions to address the underlying issues, potentially saving you time and money in the process.

Why does the check engine light come on?
The check engine light can come on for various reasons, including simple issues like a loose gas cap or more complex problems. It’s not always an indication of an expensive repair.
How can I find out why my check engine light is on?
You can use a basic OBD2 scanner to read the codes and find out what is wrong with your car. By researching the codes online and understanding the issue, you can address it yourself or be informed when seeking professional help.
Where is the OBD2 port located in most vehicles?
The OBD2 port is commonly located under the dashboard and has a trapezoid shape. It may be covered or in the fuse panel, but in most cases, it can be easily accessed.
How do I clear the check engine light after addressing the issue?
After fixing the problem, you can use the OBD2 scanner to erase the codes. Additionally, the scanner can help determine the readiness of the vehicle for an emission test.
What should I do if I have incomplete readiness for an emission test?
If the readiness for an emission test is incomplete, it is recommended to wait for a few driving cycles for the systems to check properly before attempting the test. Once all systems show okay, the vehicle can be taken for an emission test.
Why is it important to research the codes found by the OBD2 scanner?
Researching the codes found by the OBD2 scanner can provide valuable insight into the issue with the vehicle. Understanding the problem can help in making informed decisions, potentially saving on repair costs.
