Types of OBD2 Gauges

OBD2 gauges can be broadly categorized into three main types: basic code readers, handheld scan tools, and Bluetooth/Wi-Fi adapters.

Basic Code Readers

These entry-level devices are designed primarily to retrieve and clear diagnostic trouble codes (DTCs). They are generally affordable and easy to use, making them ideal for beginners. However, their functionality is limited, and they typically don’t provide live data or advanced diagnostic capabilities.

Handheld Scan Tools

These devices offer a wider range of features compared to basic code readers. They can read and clear codes, display live data, perform some diagnostic tests, and even offer graphing capabilities. Handheld scan tools are suitable for both DIYers and professionals who require more in-depth diagnostic information.

Bluetooth/Wi-Fi Adapters

These adapters connect to your vehicle’s OBD2 port and transmit data wirelessly to your smartphone or tablet. They often work in conjunction with dedicated apps, offering a convenient and portable solution for monitoring vehicle performance and diagnosing issues. Considering an OBD2 tablet app? These adapters might be the perfect solution.
