About Panlong OBD2 Scanners
Panlong OBD2 Scanners is a community-driven diagnostic brand focused on practical, accessible vehicle diagnostics for everyday drivers, enthusiasts, and independent mechanics. For more than 11 years, the brand has specialized exclusively in OBDII tools, refining a product line built around reliability, wide compatibility, and real-world usefulness rather than unnecessary complexity.
The idea behind Panlong is simple: modern vehicles generate valuable diagnostic data, but accessing it should not require expensive professional equipment or ongoing subscriptions. Panlong scanners are designed to bridge that gap by turning a smartphone or a compact handheld device into a capable diagnostic tool that delivers clear, actionable information about a vehicle's condition.
The product lineup is centered around two core categories. Bluetooth OBD2 scanners connect directly to iOS and Android devices, transforming a phone into a live diagnostic dashboard. These scanners read and clear engine fault codes, turn off the Check Engine Light, display real-time sensor data, and support advanced functions such as freeze frame analysis, I/M readiness checks, EVAP tests, and O2 sensor monitoring.
For users who prefer a standalone solution, Panlong also offers wired OBD2 scanners with built-in displays. These plug-and-play devices require no phone, no pairing, and no internet connection. In addition to full OBDII diagnostics, selected models support oil reset and maintenance interval reset functions.

What Our Customers Say
9,000+ verified reviews on Amazon
"I bought two of these to keep in my sons' cars. They work well. I pair them with the Car Scanner Pro app. It can pull SRS (airbag) codes, which saved me from having to buy a really expensive, pro-style scanner tablet. I was pleasantly surprised to find that this scanner will even speak the J1939 protocol used in heavy duty trucks."
Obi-Wan-YJ
"Nice scanner - actually is my second one. Really good quality - easy to connect. This works with Dr. Prius, also Torque, Torque Pro. I've used these on many vehicles and always get better data and more info than almost every single other more expensive unit. This is a great product - CAN NOT RECOMMEND ENOUGH!"
Gaia
"Love it. I tried a couple other new OBDII scan tools prior to this that did not work with my older vehicles even though they were supposed to. This one DOES work and it is super easy to use. In fact, I am going to get another for my brother to have."
Jacci McKenzie
"This works great with an android phone and Torque Pro app. I have one in all of my vehicles now. I use it to read and clear codes in all my vehicles and I also use this to run gauges in my 05 powerstroke to monitor lots of PIDS."
Chris
"Purchased this to diagnose some codes on my Subaru Forester. Used it with the Torque Pro app, definitely gives me peace of mind in knowing I can see codes if my dashboard ever lights up again. Allowed me to fix the small things myself which is a great money saver."
Gloria
"Works out of the box with MG ZS EV 2024 model, using the Car Scanner Android app. I was able to clear some error codes as well. The data displayed is accurate."
