If you’d told me I’d be writing a glowing review of the Foxwell NT301 car diagnostic scan tool, I would have been skeptical. Initially, after ordering the NT301, doubts crept in. Would this OBD2 scanner actually be useful, or just another gadget? My first impression upon receiving the package wasn’t encouraging. The size seemed bulky, perhaps unnecessarily so, reminding me of larger units like the Konnwei KW850. I even considered it might just become a backup to my trusty Ancel AD410, a code reader I already owned and kept in the glove box.
However, my preconceived notions were completely overturned the moment I plugged the Foxwell NT301 into my car’s OBD II port and started testing. This scan tool turned out to be a genuine surprise, earning its place as a standout in my collection of OBD II code readers. My initial lukewarm feelings quickly transformed into admiration for its capabilities and user-friendly design.
Of course, like any product, the Foxwell NT301 isn’t without its minor drawbacks, which I’ll address later in this review. These points will offer a balanced perspective, helping you decide if this car diagnostic scan tool is the right choice for your needs, or if you should consider other options.

First Impressions and Unboxing
As mentioned, my initial expectations for the NT301 were low. Comparing its dimensions to my Ancel AD410, I wondered if I’d made the right choice. Despite these doubts, I decided to give it a fair chance. This decision proved wise. Although the physical unit didn’t immediately wow me upon arrival, plugging it into my vehicle sparked an instant positive reaction.
Holding the NT301, it felt surprisingly manageable. Its size wasn’t as cumbersome in hand as I’d anticipated from the dimensions. I could comfortably operate it with just one hand. The buttons immediately stood out – soft, responsive, and with a satisfying bounce-back action, a noticeable improvement over the stiffer buttons of the Ancel AD410.
The color display and the overall feel of the device in my hands quickly shifted my opinion. I became eager to explore its features and see what this car diagnostic scan tool could do.
The packaging itself was simple and functional: a transparent plastic clamshell case displaying the NT301 prominently, with a USB update cable and a user manual included. Nothing fancy, but everything needed was there.
Key Functions and Capabilities
The Foxwell NT301 is positioned as a basic code reader, focusing on essential OBD II diagnostics. What truly distinguishes it is how effectively and user-intuitively it performs these core functions. So, what did I discover when I put it to work?
Basic Code Reading & DTC Erasure
Connecting the Foxwell NT301 to a working OBDII port, it effortlessly retrieved any present OBD II error codes. Crucially, it provides a concise explanation of what these codes signify. For many car owners and DIY enthusiasts, a DTC like P0113 might be meaningless. However, the NT301 translates this into “Intake Air Temperature Sensor 1 Circuit High,” instantly providing context and a starting point for understanding the potential issue.
Need to clear codes after a repair? The NT301 makes it simple. A dedicated button provides quick code erasure, or you can easily access the function through the menu options. The process is straightforward and efficient.
Dedicated Home Button
A surprisingly uncommon feature on many modern OBD II scanners, the Foxwell NT301 includes a dedicated Home button. If you need to quickly exit a function and return to the main menu, simply press and hold the Home button. This immediately clears the current screen and takes you back to the home page, ready for a fresh start. This is a time-saving feature, particularly useful in busy garage environments.
Live Data Streaming
Live data is crucial for understanding a vehicle’s real-time health. Some problems, like a restricted air intake leading to excessive fuel consumption, might not trigger immediate DTCs. Standard code scans might miss these issues entirely.
However, by monitoring live data and comparing readings from sensors like the MAF (Mass Air Flow sensor) against expected values, you can quickly pinpoint areas needing attention. This is why live data capability is a must-have for any useful code reader. Thankfully, the Foxwell NT301 includes this essential feature, making it a valuable diagnostic tool.
Advanced DTC Lookup
Going beyond basic code reading, the NT301 offers a DTC lookup function, essentially a built-in library of Diagnostic Trouble Codes. Enter a code, press ‘ENTER,’ and you get the code definition. However, this is more than just a simple definition.
The NT301’s DTC lookup provides advanced information, suggesting potential causes and related issues that could trigger the specific code. This extra detail is invaluable, especially for less experienced DIYers, helping them understand not just the code itself, but also the possible underlying problems.
Standout Features of the Foxwell NT301
Beyond the expected basic functions, the Foxwell NT301 boasts several notable features that elevate it above many standard code readers. These are the features that truly set it apart.
DTC Explanations – No Need for Google
DTCs are just codes without context. Understanding their meaning and potential causes is essential for effective vehicle diagnosis. Often, car owners and DIY mechanics resort to search engines to decipher codes.
The Foxwell NT301 eliminates this step. Immediately upon displaying a code, it provides the definition. Furthermore, by pressing ‘ENTER,’ the NT301 goes a step further, listing likely causes for that specific DTC. This thoughtful addition makes the NT301 exceptionally user-friendly, especially for those less familiar with diagnostic codes. It’s a feature that should be standard on all code readers, regardless of their complexity.
Dedicated Erase Button for Quick Code Clearing
While DTC erasure is a common feature, having a dedicated button for it is not. Many code readers require navigating menus to clear codes. The NT301’s dedicated erase button offers significant convenience and time-saving. Simply highlight the codes you want to clear, press the button, and they’re gone. You can even do this while waiting at a traffic light – it’s that quick.
Robust Protective Case
OBD II code readers often endure rough handling – accidental drops, greasy hands, and general wear and tear. Many don’t survive long under these conditions, often failing within a few years.
The Foxwell NT301 addresses this with a built-in protective case, a soft but durable outer layer over the main housing. This protective coat absorbs shocks from drops and minimizes dirt accumulation on the device itself. It’s a simple yet ingenious design feature that enhances durability.
Responsive and Satisfying Keys
After dealing with vehicle issues, sometimes a bit of tactile satisfaction is welcome. The NT301’s keys offer just that. They are large, soft to the touch, and depress with a satisfying give, providing immediate feedback. When released, they bounce back smoothly and responsively. This may seem minor, but it contributes to a positive user experience, especially when using the tool frequently. It’s a small detail that enhances usability and even provides a bit of stress relief.
Vehicle Compatibility
The Foxwell NT301 demonstrates broad compatibility with most post-1996 vehicles I’ve tested. It functions reliably, delivering a high percentage of its features across different makes and models.
However, my testing hasn’t included newer hybrids (including plug-in hybrids), electric vehicles, sports cars, or luxury brands like Rolls Royce. 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 to Consider
Despite its many positives, the Foxwell NT301 has a few limitations worth noting. These aren’t deal-breakers, but awareness is key to making an informed decision.
Non-Backlit Keys
While I haven’t personally used a code reader with backlit keys, and they might be uncommon at this price point, it would be a valuable addition to the NT301. Given its solid construction, backlit keys would enhance usability in low-light conditions. The excellent feel and responsiveness of the keys are almost negated by the lack of backlighting when you need to use it in the dark.
Basic Scanner – Limited Module Scanning
The NT301 is a basic code reader, meaning it primarily focuses on engine and emissions-related diagnostics. It doesn’t offer scanning capabilities for additional modules like the transmission (tranny) or ABS (Anti-lock Braking System). While these systems are generally reliable in well-maintained vehicles, the ability to scan all modules provides peace of mind, ensuring there are no hidden issues. This is particularly relevant when troubleshooting complex problems where you want to rule out all possibilities.
Cord Length Could Be Longer
The NT301’s cable is adequately long for comfortable use in most vehicles, regardless of seating position. However, after using scanners with exceptionally long cords, like the Konnwei KW850, a longer cable feels more convenient. The extra length allows for greater flexibility, letting you operate the scanner from outside the vehicle if needed. While not a major drawback, a slightly longer cord would be a welcome improvement.
Alternatives to the Foxwell NT301
The Foxwell NT301 is a strong contender, but it might not be ideal for everyone. If you prefer a more compact scanner, or one with fewer buttons, or something that fits more easily in your palm, consider alternatives.
The Ancel AD410 code reader remains my glove box scanner of choice for over five years. It’s compact, reliable, and a great basic tool.
For a more powerful yet budget-friendly option, the TopDon TopScan is worth exploring. Despite its small, pocket-friendly size, it offers advanced features like ABS and transmission module scanning. It’s also Bluetooth-enabled, working with smartphones and various vehicle models.
Final Verdict: Should You Buy the Foxwell NT301?
Yes, absolutely. Without hesitation, I recommend the Foxwell NT301.
In my comparison of the Foxwell NT201 vs NT301, I highlighted the NT301’s clear superiority. While the mentioned limitations are worth considering, they are not significant enough to detract from its overall value and performance. Take a moment to review the cons and ensure they are acceptable for your needs.
