Onboard Diagnostics (OBD) is a system that works via sensors and computers in a car so as to display information that’s vital to your car’s operation, and how it works.
Previously, OBD was in the form of gauges, tachometers, fuel level and oil pressure indicators, which were used to give information about the condition of a car. But today, OBD2 scanners can be used for self-diagnostics and reporting by allowing a single scanner to provide data access to these systems.
When looking for the right OBD2 scanner, you’ll need to consider its features, vital information it offers, price, flexibility, the data you can access, and compatibility with other devices such as Android or iOS.
This OBD2 scanner is designed to work on all vehicles purchased in the U.S. model year 1996 or newer, as a guarantee from the manufacturer, whether your car runs on gas, diesel or hybrid, old/new – it will work with it.
Its features include a monitor and analyzer to check O2 sensors, fuel trim, air fuel ratio, DPF/Oil/Coolant temp, fuel pressure, and read and clear your check engine light, all at a reasonable price.
Some tasks you can fulfill with this scanner include reading your check engine light codes, reset/clear the check engine light, pull sensor readings related to the OBD2 of your car or emissions system, graph sensor readings for different data such as O2, AF, throttle, speed, fuel trim, balance rates, RPMs, and load value.
You can also perform smog/emissions tests, data logging and map-based tracking on your sensor readings.
However, it only works with an Android or Windows based device only, and requires a third-party app to work, preferably Torque Pro.
The BlueDriver OBD2 scanner is a professional diagnostic tool officially licensed and certified for use on iOS and Android devices, for use with all major car brands.
