Have you ever found yourself staring at a check engine light, wondering how to get rid of it? The light means there’s a problem with your car’s emissions system, but what if the issue has been fixed and the light won’t go away? One possible solution is to clear the OBD2 codes.

OBD2 codes are diagnostic trouble codes that are stored in your car’s computer. These codes can be used to identify the source of the problem and help you fix it. Once the problem has been fixed, you can clear the codes and the check engine light will go away. However, some OBD2 codes are permanent and will not go away unless you take specific steps to clear them.

Types of OBD2 Codes

There are many different types of OBD2 codes, each of which is a unique identifier for a specific problem.

Permanent codes are stored in the car’s computer and will not be erased when the battery is disconnected. These codes are typically used to track major problems that could affect the safety or emissions of the vehicle.

Temporary codes are stored in the car’s computer but will be erased when the battery is disconnected. These codes are typically used to track minor problems that do not affect the safety or emissions of the vehicle.

How to Clear Permanent OBD2 Codes

There are two ways to clear permanent OBD2 codes:

Using a scan tool

A scan tool is a device that can be used to read and clear OBD2 codes. Scan tools can be purchased for a relatively low price, making them a good investment for anyone who does their own car repairs.

Disconnecting the battery

Disconnecting the battery will also clear OBD2 codes, but it is not as effective as using a scan tool. When you disconnect the battery, you are also resetting the car’s computer. This can cause the car to lose some of its settings, such as the radio presets and the clock.

Consequences of Clearing Permanent OBD2 Codes

Clearing permanent OBD2 codes can have several consequences:

Clearing the codes could prevent the car from passing an emissions test.

It could make it difficult to diagnose future problems. If the check engine light is on, it is a sign that there is a problem with the car. If you clear the codes, you may not be able to tell if there is still a problem.

It could void your warranty. If your car needs emission repairs in the future, a voided warranty can be a big headache.

It is also important to remember that clearing the codes will not fix the underlying problem. If the check engine light is on, it means there is a problem with the car that needs to be fixed. Clearing the codes will only make the light go away, it will not fix the problem.
