1. What Is an Aukey OBD2 Scanner?
An Aukey OBD2 scanner is a device used to diagnose issues in your vehicle by reading data from its On-Board Diagnostics (OBD) system. OBD2 scanners help you retrieve diagnostic trouble codes (DTCs), monitor vehicle performance, and clear fault codes, assisting in identifying and resolving problems efficiently.
OBD2, or On-Board Diagnostics II, is a standardized system used in most vehicles since 1996 to monitor and control engine performance, emissions, and other essential systems. According to the Environmental Protection Agency (EPA), OBD2 systems help reduce vehicle emissions by alerting drivers to potential problems that can affect emissions control devices. The OBD2 system works by using various sensors to monitor engine parameters and other systems. When a sensor detects a problem, it sends a signal to the vehicle’s computer, which then stores a diagnostic trouble code (DTC).
Aukey, a well-known brand for electronic accessories, offers OBD2 scanners that are user-friendly and suitable for both car enthusiasts and professional mechanics. According to a study by Grand View Research, the global automotive diagnostics market is expected to grow, driven by increasing vehicle complexity and stringent emission regulations.
