If you had told me I’d be writing this Foxwell Nt301 Obd2 Scanner Review with genuine enthusiasm, I would have been skeptical. Honestly, when the NT301 arrived, I had second thoughts and wondered if it would even be worth my time to test.
My initial impression wasn’t great. Looking at the box, the NT301 seemed bulky, potentially larger than necessary, bringing to mind scanners like the Konnwei KW850. At best, I imagined it would end up as a backup, perhaps replacing my current glove box scanner, the Ancel AD410.
However, my skepticism was completely overturned the moment I plugged the Foxwell NT301 into my car’s OBD II port and started testing.
To say the Foxwell NT301 surprised me is an understatement. It truly earned the title of ‘queen of OBD surprises’ in my book. My lukewarm initial feelings transformed into admiration, and I gained a newfound respect for this little OBD II code reader within my collection.
That being said, like any product, the Foxwell NT301 isn’t without its drawbacks, which I’ll address later in this review. These points will offer a balanced perspective, helping you decide if the NT301 is the right OBD2 scanner for your needs, or if you should look elsewhere.
But first, take a look at the Foxwell NT301 OBD2 scanner on Amazon.

Foxwell NT301 OBD2 Scanner Review: First Impression and What’s in the Box
As I mentioned, I had mixed feelings leading up to the NT301’s arrival. Based on online dimensions, it seemed larger than my Ancel AD410, making me question my decision to review it.
Still, curiosity got the better of me, and I allowed the order to proceed. This spur-of-the-moment decision proved wise when, despite my initial underwhelming impression of the physical unit, I plugged it into my vehicle. The experience that followed brought a smile to my face.
Holding the NT301 in my hand, it didn’t feel as bulky as the dimensions suggested. I could comfortably operate it with one hand. Immediately, I noticed the keys were soft and responsive, bouncing back nicely after each press – a tactile improvement over the Ancel AD410.
The color display and the overall feel of the code reader in my hands instantly shifted my perception. I became eager to explore its features.
The packaging was simple and functional. The NT301 came in a transparent plastic clamshell, device facing forward, update cable behind, and a user manual tucked in between. No frills, just the essentials.

Functions & Abilities
The Foxwell NT301 is, at its core, a basic OBD2 scanner. It’s not loaded with advanced features, but what truly distinguishes it is how effectively it executes its core functions: code reading and basic OBD II diagnostics.
So, what did I discover when I put it to work?
1. Basic Code Reading & DTC Erasure
Connecting the Foxwell NT301 to a working OBDII port is straightforward. It quickly retrieves OBD II error codes, if present, and importantly, provides a concise explanation of each code.
For many car owners or DIY mechanics, a Diagnostic Trouble Code (DTC) like P0113 might be meaningless. However, the NT301 clarifies this by displaying “Intake Air Temperature Sensor 1 Circuit High” in this instance. This clear description provides context, giving you a much better understanding of the potential issue.
Need to clear codes after making a repair? The NT301 makes it simple. There’s a dedicated “Erase” button for quick code clearing, or you can access the erase function through the menu options.
2. A Dedicated Home Button
A somewhat unusual but highly appreciated feature on the Foxwell NT301 is the dedicated “Home” button. In today’s OBD II scanners, such a direct return-to-home function is surprisingly rare.
If you need to quickly exit what you’re doing and return to the main menu, you don’t have to fumble through menus or guess which button to press. Simply press and hold the “Home” button, and you’re instantly back at the starting point.
This is a smart, time-saving feature, especially valuable in the often-hectic environments of DIY garages and professional workshops.
3. Live Data Reading
Live data is crucial for understanding a vehicle’s real-time health. Some problems, like a restricted air intake leading to poor fuel economy, might not trigger a standard DTC immediately.
Relying solely on DTC scans to identify these issues can be ineffective. However, examining live data streams and comparing values, such as Mass Air Flow (MAF) readings against expected ranges, can quickly pinpoint areas needing attention.
This is why I believe live data capability is a minimum requirement for any worthwhile code reader. If a scanner lacks this function, its diagnostic value is severely limited.
Fortunately, the Foxwell NT301 includes live data functionality. This feature is essential for effective diagnostics, and you’ll find it invaluable when troubleshooting more complex vehicle issues.
4. DTC Lookup (With Advanced Option)
Adding to its functionality, the NT301 includes a DTC lookup feature, essentially a built-in library of Diagnostic Trouble Codes. Enter a code, press “ENTER,” and the scanner provides the code definition.
However, this DTC lookup is more advanced than typical basic scanners. It doesn’t just provide the code definition – which can still be confusing for unfamiliar codes or casual DIYers.
The NT301 goes further by suggesting potential causes or problems that could trigger the specific DTC. This makes it easier to understand not just the code itself, but also the underlying issues that might be causing it.
Other Notable Functions & Features
Beyond the essential functions of a basic code reader, the Foxwell NT301 has several other notable features that elevate it above the ordinary.
These features set it apart and place it in a class of its own within the realm of basic OBD2 scanners.
They include:
1. DTC Explanations, Negating Google
DTCs are, by their nature, technical. Without clear explanations of what these codes mean and what to investigate, DIYers and car owners can be left relying on mechanics, even with a code reader in hand.
Often, vehicle owners and DIYers resort to Google or other search engines to decipher DTCs. The Foxwell NT301 eliminates this step by providing the meaning of the code directly, immediately after it’s displayed.
But the NT301 goes a step further. Upon pressing “ENTER” after a code is displayed, it provides a list of potential causes that could trigger the DTC.
This thoughtful addition makes the NT301 stand out among basic code readers. It’s a feature that should be standard in all code readers, regardless of their complexity.
2. Dedicated Erase Function
The ability to clear DTCs is a standard function on virtually every basic code reader. It’s not unique in itself.
However, very few code readers offer a dedicated button specifically for this function – a button that doesn’t require navigating through menus.
This dedicated “Erase” button saves time and adds convenience. Simply highlight the DTCs you want to clear and press the button. Codes are cleared instantly.
This can even be done during brief stops, like waiting at a traffic light, adding a level of real-world usability.
3. A Solid Protective Case
OBD II code readers often endure harsh conditions. From accidental drops to handling with greasy hands, they rarely receive gentle treatment.
This rough handling contributes to the short lifespan of many code readers. Traditionally, many units are retired within three years due to damage or malfunction.
The Foxwell NT301 is built to withstand this. It features a protective outer case, adding an extra layer of shock absorption and defense against dirt. This robust design significantly improves durability.
This protective case is a genuinely smart and practical design element.
4. Nice, Large, Bouncy Keys
After a frustrating day wrestling with vehicle issues, sometimes you just need a little tactile satisfaction. The Foxwell NT301’s keys can surprisingly provide this.
The large keys are soft to the touch and depress easily, offering a satisfying click. When released, they spring back with a pleasant bounce.
It might sound trivial, but these keys contribute to a more positive user experience. On days when I’m less patient, the tactile feedback of these keys is a small but welcome detail.
…it’s all about knowing what helps you stay calm!
Foxwell NT301 Vehicle Compatibility
The Foxwell NT301 demonstrates broad compatibility, working seamlessly with most post-1996 vehicles I’ve tested. It consistently delivered a high percentage of its functions, often exceeding 80%.
While widely compatible, I haven’t tested the NT301 with newer hybrid vehicles (including plug-in hybrids), electric cars, or sports cars. Luxury models like Rolls Royce also remain untested.
If you own one of these vehicle types, it’s advisable to contact Foxwell directly to confirm compatibility with your specific make and model before purchasing the NT301.

Limitations
Despite its strengths, the Foxwell NT301 isn’t perfect. Like all products, it has limitations. These aren’t deal-breakers, but it’s important to be aware of them.
1. The Keys Aren’t Backlit
While I haven’t personally used a backlit code reader before, and they might be rare at this price point, given the NT301’s solid build, backlit keys would be a welcome addition, even if it slightly increased the cost.
The excellent feel and responsiveness of the keys are almost undermined by the lack of backlighting, especially for use in dimly lit environments.
2. The NT301 is a Basic Code Reader
Beyond the lack of backlit keys, the NT301 is fundamentally a basic code reader. It doesn’t offer advanced module scanning capabilities, such as transmission (tranny) or ABS systems.
While these modules are typically reliable on well-maintained vehicles, it’s reassuring to scan all modules to ensure there are absolutely no issues.
This is particularly true when facing a problem that’s difficult to diagnose, and you’re hoping for any fault code to appear.
3. The Cord Isn’t the Longest…
Finally, the NT301’s cable isn’t the longest available. It’s certainly long enough for comfortable use in any vehicle, regardless of seating position.
However, after using the Konnwei KW850, with its exceptionally long cable, I’ve come to appreciate the extra reach. The KW850’s longer cord allowed me to stand outside the vehicle while still easily using the scanner.
Now, cable length is something I consider when evaluating OBD II code readers – a slightly unexpected preference.
Alternatives to Consider
The Foxwell NT301 is a reliable code reader. However, if you prefer a smaller device, fewer buttons, or a more pocket-friendly option, it might not be the ideal choice.
If that’s the case, consider the Ancel AD410 code reader. It’s been my trusted glove box scanner for over five years, and I highly recommend it for its compact size and reliability.
For those seeking a more powerful yet still affordable option, the TopDon TopScan is worth exploring. It’s a small, pocket-sized scanner, but surprisingly capable, offering module scanning for ABS, transmission, and other systems – features typically found in more expensive scanners.
Furthermore, the TopDon TopScan is Bluetooth-enabled, working seamlessly with smartphones and a wide range of vehicles.

Should You Buy the Foxwell NT301?
Yes – absolutely. Without hesitation.
In my Foxwell NT201 vs NT 301 comparison, I demonstrated the clear superiority of the NT301.
However, it’s important to re-examine the limitations mentioned earlier and decide for yourself if they are deal-breakers. For most users needing a reliable and user-friendly basic OBD2 scanner, they won’t be.
