Since their introduction, OBDII Bluetooth scanner tools have become a favorite among part-time mechanics and professionals to find and fix engine problems.
They are low-cost engine diagnostic tools that can help troubleshoot a problem.
For example, if an engine light comes on, which gives no indication of the problem, a small, low-cost OBDII adapter code scan tool can be used to quickly find the problem.
Bluetooth OBDII dongles are easy to use and Pair with a smartphone or laptop to display a vehicle problem.
Bluetooth OBDII dongles are relatively new to the automotive world but do work well once they are understood, mainly the app used.
The most popular app is called Torque, but there are many more available free and paid.
Personally, I use whichever app is free since all I need them to do is scan for the code and clear it if necessary; almost any OBD app will do this.
The paid versions do come with more features if that is needed, such as monitoring oil pressure, temperature, and other engine vitals in real-time.
There are many good units available, with some of our favorite picks below.
As always, be sure to read reviews on Amazon, here, or elsewhere to be sure a unit is a right pick for you.
