10 Best OBD2 Scanners With Misfire Detection for 2026 – Expert Reviews

Customer Review: “Awesome OBD2 Dongle. Pairs quickly with my droid phone and the connect is lightning fast, I’d say real time. I bought it to link up to Torque Pro app for my 2014 Mini Clubman S but ended up using the OBDLink app instead. The OBDLink app has a great assortment of gauges and picks up all the signals and sensors on the N18 engine without setting up custom PIDS. This was a big surprise because that’s why I purchased Torque Pro. However (for BMW/MINI users) some of the sensors are not readily visible to Torque Pro without adding custom PID formulas – like boost readings. Great dongle, best I’ve had yet. Additionally, the OBDLink app also gives a lot of BMW specific trouble codes. That was a nice surprise as well.”

Customer Review: “Product works as expected. Very straight forward setup with the app that is provided. Works with ForScan, SideCar, Car Scanner, and of course OBD-Link.”

Customer Review: “Picked this up to quickly check engine codes without dragging the car to a shop, and it works great. Plugged it into the OBD2 port and it powered on instantly, no batteries or setup headaches. The menu is pretty straightforward and easy to navigate, even if you’re not super technical.It reads and clears codes fast, and I like that it shows descriptions instead of just numbers, which saves time googling everything. Screen is clear and bright enough to read even in daylight. Build quality feels solid and the cable is thick and durable.For basic diagnostics and maintenance checks this thing is honestly perfect. Already saved me a trip to the mechanic. Great value for the price.”

Customer Review: “I really liked this VECOONEEN OBD2 scanner. It’s very practical and easy to use. I tested it on my Prius, and it quickly showed that the issue was a failing oxygen sensor.The scanner provided accurate information and saved me time by helping identify the problem right away. A great tool to have for basic diagnostics.”

Customer Review: “This isn’t a high‑end mechanic’s scanner, but it does exactly what most people need at home. It pulls accurate codes, reads freeze‑frame data, and gives you a clear idea of why the check engine light is on. For basic diagnostics, it’s fast, simple, and dependable.It has already saved me time and money by letting me understand the issue before going to a shop. For anyone who wants a straightforward OBD2 tool without spending a fortune, this one gets the job done.”

Customer Review: “Does the job pretty well. You can see live data and diagnose your car for any major issue without even going to the mechanic which would cost you $75-125 for doing the same thing. Very easy to install and operate. I had to use once and it read the codes accurately.”

Customer Review: “Easy to use, great quality and works good. Worth the money.”

Customer Review: “These do the trick, nothing fancy but they work well. I like orange easier to find in shop.”

Customer Review: “Perfect little OBD scanner. Does the job well. Live reading is awesome and works well. And for the price? You can’t beat it. Super easy to plug in and within minutes have your codes from your check engine light. Worth it!”

Customer Review: “Awesome little tool for the price.It works very good.”

Customer Review: “Helped us fix a $.50 issue without going to a mechanic. Works great.”

Customer Review: “Does exactly what it’s supposed to do for simple codes. Helped diagnose easy problems without going anywhere!!”

Customer Review: “Great and easy to use. Using the app also help see all results.”

Customer Review: “It works good, connected to my phone with no problem. Showed the codes that caused check engine light to be on and allowed me to clear them.”

Customer Review: “This is a very basic OBD2 scanner and battery tester. The unit starts right up as soon as it’s plugged into the OBD2 port. There are quite a few tests you can run on this little handheld. I have another OBD2 scanner and this one was about the same dimension, but it’s not as thick as my other one. It’s nearly the same size of my standard scanner, just not as thick or as heavy. The scanner seems to be kind of rugged so it should be able to survive being dropped.As far as functionality, I ran it through most of the tests that were available, and it seems to have done pretty good. This is a very basic scanner that does not have a left or right arrow and isn’t a touch screen, but at the price I paid for this unit, it’s definitely worth it. While this won’t be my go to scanner, I will probably stay in my truck so I can lug it around in my truck instead of it being in my garage.The only issue I had with this scanner is that it glitched while I was running one of the tests, but it corrected itself once I unplugged and replugged it back into the port.Overall, it functioned just as well as my more expensive scanner but at a very reasonable price.”

Customer Review: “I’ve used this directly on my car, and it works exactly as advertised. You simply plug it into the OBD2 port under the dashboard on the driver’s side, and it powers on immediately.Once connected, it can read engine codes, display live engine data, and even show your battery voltage. That’s a really useful combination in such a small device.What I like most is how lightweight and compact it is. This is something you can easily keep in your car at all times, so it’s there when you need it.Yes, you can go to auto parts stores to have your codes read, but having your own scanner is a big advantage—especially if you’re on the road, far from a shop, and a warning light comes on. Instead of guessing whether you should keep driving, pull over, or call a tow truck, this tool gives you immediate answers.For road trips or just peace of mind in general, it’s a smart thing to have in your vehicle.At around $18, the value is excellent. It’s hard to justify not having one, considering how useful it can be in a pinch.Overall, I highly recommend keeping one of these in your car.”

Customer Review: “Works great with my iPhone 16Pro running iOS 26.3 and 26.2.1. Just used this morning with Carista app on iPhone customizing my 4Runner settings. Haven’t tried on iPad yet.One app took a long time to connect but finally did “car scanner elm obd2”. Not sure why though. But it works great after it connects and lots of customization abilities in free version, surprising! But great.”

Customer Review: “My second unit. I had one for my JKU. Now have a Gladiator. Works great. Way cheaper and easier to operate than the tazer ones.”

Customer Review: “Great product worth every penny app is a bit pricey if your not going to use it often but a must have tool for car repair tells you codes and exact issues also tells you step by step how to fix it. As well as an AI mechanic to asked question and call support as well it helps you know a price range for shops so you don’t get over charged for repairs. I used it yesterday when looking at a car which had no codes on the dash FIXD told me the pending codes and also made me aware the codes were recently cleared which gave me such piece of mind. Knowing a serious community de was cleared prior to me looking at the vehicle. I’ve decided to pay for the year subscription”

Customer Review: “This little item works great, but it has a small caveat if you want its full functionality.As OBDII scanners go, this one does the job at a fraction of the price of a professional scanner. It shows all the information on the screen in an easy to set up software with an intuitive menu. Easy for even the least mechanically inclined people to use. However, you’ll need a separate iPhone, iPad, or Android device to install the app onto.It color codes the issues as to their importance. Green means you should be fine and it’s more of a suggestion than an issue, Yellow means check it out soon or have a mechanic take a look, Red means you should probably stop driving your car and set it on fire. Just kidding. But the information is displayed fully with the OBDII codes along with the explanations as to what they are. In my case, there was a Stored Code and a few Pending Codes. The Stored Code defined what the code is, however the Pending Codes showed ‘Unknown Issue’. I had to go online later to look them up. There’s also an option to clear the dash lights that did not work for me. So does the scanner work? Definitely. Is it worth it? Probably not, and here’s why.The caveat I mentioned? You have to purchase their Premium version at a yearly fee of $99.00 if you want to unlock the scanner’s full potential. It includes; \”Cost and repair estimates from the Identifix database, Unlimited calls to our FIXD Mechanic Hotline for a trusted second opinion and DIY help from our network of ASE certified mechanics, And much more! FIXD Premium is a monthly subscription that is optional and is not required for use of the sensor.\”After the purchase price of $37, that makes this little bugger $137 right off the bat, with an additional $99/year after that. However, they do let you try it free for one week (cancel at any time). If you’re using this scanner for multiple vehicles, and you’re getting paid for it, then you might find the fee not so much of an inconvenience. However, if you’re like me and are only using it on your daily driver, how often do you think you’re going to use it to qualify that fee? I used it this once, found the codes, and now it’ll probably sit on a shelf until the next time the need arises for it. And since I’m mechanically inclined, I can resolve the issues on my own. But, again, \”the subscription is optional and is not required for use of the sensor.\”If you want a scanner that offers more functionality with no extra costs involved then purchase one of those instead. But if you’re an average Joe or Jolene and you just want to see why your car has those dash lights always on, then this little guy does the job just fine.”
