Understanding OBD2 Scanners
An OBD2 scanner, in its simplest form, is a device that plugs into your car’s OBD2 port to access and interpret data from the vehicle’s computer system. While professional-grade scanners can be expensive and feature-rich, the best low price OBD2 scanners focus on providing core diagnostic functions effectively. Regardless of price, a functional OBD2 scanner should reliably:
- Establish communication with your vehicle’s computer system.
- Accurately read and display diagnostic fault codes.
- Allow you to clear fault codes after addressing the underlying issue.
It’s worth noting that most basic OBD2 scanners, even within the best low price category, are primarily designed for reading and clearing engine fault codes. They typically do not handle advanced functions like resetting service lights for systems like ABS or SRS, or managing oil life monitors. However, resources like Haynes AutoFix can often supplement your best low price OBD2 scanner by providing step-by-step guidance for these more complex reset procedures and diagnostics.

How OBD2 Technology Works
OBD stands for On-Board Diagnostics. The OBD2 system is standardized across the automotive industry, featuring a 16-pin port that has become a standard feature in vehicles. This standardized port has been mandatory for all gasoline passenger cars sold in Europe since January 1, 2001, and for diesel cars since 2004 (referred to as EOBD in Europe, and OBD2 outside of Europe).
The OBD2 port conveniently supplies power to the scanner, eliminating the need for separate batteries or power cables for most devices, including many best low price OBD2 options. This plug-and-play functionality makes even a basic, affordable OBD2 scanner incredibly user-friendly for quick car diagnostics.
