Have you ever been driving your 2002 Honda Accord, only to have the dreaded “check engine” light come on? You know you need to get it checked out, but how do you even know what’s going on? The good news is that with a little knowledge of your car’s OBD system, you can start to diagnose the problem yourself.
What is OBD?
OBD stands for On-Board Diagnostics. It’s a system that’s been built into cars since 1996, and it’s designed to monitor your car’s performance and detect any issues that might be occurring. When a problem is detected, the OBD system will store a diagnostic trouble code (DTC) that can be read by a scan tool.

OBD is important for a variety of reasons. It can help you:
- Diagnose and fix problems: When you’re having problems with your car, a scan tool can help you quickly and accurately diagnose the issue. This can save you time and money, as you won’t have to take your car to the mechanic for a basic diagnosis.
- Avoid costly repairs: By knowing what issues are happening, you can get them fixed before they become major problems.
- Improve your car’s performance: The OBD system can help you identify problems that might be affecting your car’s fuel efficiency, power, or emissions.
