What Doesn’t Work?
It only works on Honda and Acura, so I couldn’t use it on my cousin’s Toyota. Older models like the 2001 Civic didn’t support all reset functions. Also, you need Wi-Fi to update the software, which can be annoying in the garage.

What doesn’t work?
Some functions didn’t work on older cars—I couldn’t do injector coding on my 2013 Altima. A few resets were missing on a 2012 Chrysler too. The app layout took a little time to get used to.

3.Launch CR529 – Best OBD2 Scanner Under $50
I picked up the Launch CR529 when I needed a reliable scanner under $50 that didn’t feel “cheap.” Right out of the box, it felt solid—no battery needed, just plug it into your car and go. The 2.8-inch color screen is crisp, and the one-click I/M readiness check saved me time before my inspection. I even printed a diagnostic report straight from my PC. For a scanner in this price range, it honestly punches above its weight.
Key Features
- Full OBD2 support (Mode 1 to 10), including Mode 6 & 8
- Live data in both text & graph formats
- O2 Sensor & EVAP test included
- One-click smog readiness (I/M) with red/yellow/green LED indicators

- Works on all OBD2-compliant vehicles (1996+)
What Works?
What I liked most is how fast it boots—within 5 seconds, I was scanning. The LED color indicators made smog checks super easy to read at a glance. It also stores reports, so I could email myself a PDF before taking my car in for repairs.
What Doesn’t Work?
It doesn’t read ABS, SRS, or transmission codes—just engine-related stuff. Also, the interface, while decent, isn’t touchscreen, so you’re stuck using physical buttons. And although it supports Mode 6, the data can feel overwhelming if you’re new to diagnostics.
Who Should Buy This?
If you’re a DIYer or first-time car owner, this tool is a solid win under $50. It’s perfect for people who want to check engine lights, pass smog checks, or monitor live data without diving into pro-level tools.

4.MOTOPOWER MP69033 Car OBD2 Scanner Code Reader
When I picked up the MOTOPOWER MP69033, I honestly wasn’t expecting much for the price—but it surprised me. For under $30, it gives you real-time data, freeze-frame info, and DTC code lookups right out of the box. I tested it on a 2012 Civic and a 2008 Corolla, and it instantly connected with no fuss. It runs directly off your car’s power and doesn’t need batteries, which is super handy. This thing is basic, but rock solid for engine code checks and quick diagnostics.

What Works?
I loved how fast it connected—literally took under 10 seconds once plugged in. The live data was clear and easy to read, especially with the adjustable screen contrast. It gave me the freeze frame and load values right when I needed them while diagnosing a misfire.
What Does Not Work?
It won’t read ABS, airbag, or oil reset codes, which is a bit limiting if you need full system diagnostics. The buttons feel a little cheap, and scrolling through menus takes some patience. If you’re looking for more advanced features like wireless use or full-system scans, I’ve compared the best bi-directional Bluetooth OBD2 scanners of 2025 as well.
Who Should Buy This?
If you just want to read and clear check engine lights without spending more than a dinner, this is perfect. I’d recommend it for beginners, DIYers, or anyone who wants to keep a scanner in the glove box. It’s best for basic engine-related issues, not advanced troubleshooting.
5.Autel ML529 OBD2 Scanner Review
I’ve used the ML529 on everything from my 2013 Toyota Corolla to a friend’s 2017 Ford Escape, and it handled both without breaking a sweat. It reads and clears engine codes fast, supports Mode 6 diagnostics, and the AutoVIN feature seriously saves time. What I really liked is how quickly it pulled live data and gave me freeze-frame snapshots when I was troubleshooting a rough idle. For under $80, it’s got just enough punch to feel like a pro tool without the pro price.
Features

I found AutoVIN made setup super fast—under 10 seconds on both Ford and Kia. Live data was smooth and helped me spot a misfiring cylinder right away. Mode 6 diagnostics gave me extra info most cheap scanners just don’t show.
What Doesn’t Work?
It doesn’t support ABS, SRS, or transmission codes—only engine-related stuff. The display feels a bit dated compared to modern touch tools. And while it updates online, the software interface could use a refresh.
Who Should Buy This?
If you’re a DIYer or first-time car owner, this is a smart investment under $100. It’s perfect for folks who want fast code reads and deeper OBD2 data without paying for dealer-level tools. If you work on brands like BMW, this list of the best OBD2 scanners for BMW can help you narrow it down.
5 Buying Guides for Best OBD2 Scanners Under $100
1. Focus on What You Really Need
When I started, I just needed a way to clear engine codes. But now I look for tools with live data, O2 sensor tests, and Mode 6. If you only want basics, $30–$40 scanners are fine. For more features, expect to spend $70–$100.
2. Bluetooth or Handheld?
I prefer Bluetooth scanners since I can use my phone, but handheld tools are great if you don’t want to deal with apps. Go with whatever feels easier for you. Just make sure the screen is clear and buttons are responsive.
3. Always Check for Live Data
Live data is a must for me—it shows real-time performance like RPM and fuel trim. It helped me spot issues way faster than waiting for a code. Most good scanners with live data start around $45.
4. Make Sure It Works With Your Car
Not every scanner works on every vehicle. I’ve run into issues with older models and cheap tools. Look for compatibility with OBD2 protocols like CAN and J1850, especially if you own something from the early 2000s.
5. Free Updates Are a Must
I always check for lifetime updates before buying. It’s the best way to keep your scanner useful as new vehicles come out. If updates aren’t free or easy to install, I move on to a better option.
Final Thoughts: Best OBD2 Scanners Under $100
After testing and researching dozens of tools, I found you don’t need to spend a fortune to get reliable diagnostics. Whether you’re chasing a check engine light or digging into live data, there’s a solid OBD2 scanner under $100 for you. Just focus on what features matter most to your needs. For me, a scanner that’s fast, accurate, and updateable is worth every penny.
FAQs: Best OBD2 Scanners Under $100
1. Can I get a reliable OBD2 scanner for under $100?
Yes, definitely. I’ve tested scanners in the $30 to $90 range that read codes, show live data, and even run O2 sensor tests. You don’t need to spend dealership money for accurate diagnostics at home.
2. Will these scanners work on my car?
Most scanners under $100 support all OBD2 protocols and work on cars made after 1996. I’ve used mine on everything from a 2004 Honda Civic to a 2019 Ford Escape with no issues—just check that your car is OBD2-compliant.
3. What’s the difference between Bluetooth and handheld scanners?
Bluetooth scanners connect to an app on your phone, which I find super convenient. Handheld units have built-in screens and don’t need a phone. I’ve used both, and it really comes down to what you’re more comfortable with.
4. Do these scanners read ABS or airbag codes?
Most budget scanners under $100 only read engine-related codes. If you want ABS, SRS, or transmission diagnostics, you’ll usually need to spend a bit more. Some brand-specific tools like the Kingbolen Soloscan offer limited extra system access.
