The Foxwell NT301 genuinely surprised me, earning its place as a true ‘queen of OBD surprises’ in my toolkit. From initial lukewarm expectations, my view shifted to admiration, recognizing the respect it deserves among my collection of OBD II code readers.
However, like every product, the Foxwell NT301 isn’t without its drawbacks. This review will provide a balanced perspective, outlining both the positives and negatives of this code reader, helping you decide if it’s the right OBD II scanner for your needs.

First Impressions: Unboxing and Physical Feel
As mentioned, anticipation wasn’t high when the NT301 was en route. Comparing its dimensions to my Ancel AD410, I questioned my decision. Yet, curiosity prevailed, and I allowed the order to arrive. This spontaneous choice proved wise. Despite my initial reservations about its size upon arrival, plugging it into my vehicle sparked an unexpected enthusiasm.
Holding the unit, my size concerns dissipated. It wasn’t as bulky as I’d imagined from the measurements. One-handed operation felt comfortable and manageable. The keys immediately stood out – soft, responsive, and with a satisfying bounce, a noticeable improvement over the stiffer keys of the Ancel AD410. The color display and the overall feel in hand instantly shifted my perception, igniting excitement for exploring its features.
The packaging was straightforward: a clear plastic clamshell displaying the NT301 front and center, with an update cable behind and a user manual tucked in between.
Functions and Capabilities: Basic Yet Effective
The Foxwell NT301 is undeniably a basic code reader, focusing on fundamental OBD2 diagnostics. However, its strength lies in how effectively it executes these core functions – code reading and OBD II diagnostics. So, what did I discover when I put it to work?
1. Basic Code Reading and DTC Erasing
Connected to a functioning OBDII port, the Foxwell NT301 effortlessly retrieves OBD II error codes, if present, and crucially, provides a concise explanation of their meaning. For example, the code P0113 might be cryptic to the average car owner or DIY mechanic. But, the NT301 clarifies it as “Intake Air Temperature Sensor 1 Circuit High,” immediately offering a clearer understanding of the potential issue. Clearing codes after repairs is simple. A dedicated button or a menu option provides quick access to the erase function.
2. Dedicated Home Button
A surprisingly rare but incredibly useful feature on modern OBD II scanners is the dedicated Home button found on the Foxwell NT301. If you need to quickly backtrack or restart, no fumbling through menus is required. A simple press and hold of the Home button instantly returns you to the main screen. This is a time-saver, especially in the often-pressured environment of automotive diagnostics.
3. Live Data Streaming
Live data is crucial for understanding a vehicle’s real-time health. Some issues, like a restricted air intake causing excessive fuel consumption, might not trigger standard DTCs immediately. Relying solely on code scanning might miss these subtle problems. However, analyzing live data and comparing Mass Air Flow (MAF) sensor readings against expected values can pinpoint such issues. This is why a live data function is a must-have in any code reader. Thankfully, the Foxwell NT301 includes this essential feature, proving invaluable for accurate diagnostics.
4. Advanced DTC Lookup
Adding further value, the NT301 features an advanced DTC lookup function, a built-in library of Diagnostic Trouble Codes. Simply input a code, press “ENTER,” and you receive a definition. But this isn’t just a basic definition. This advanced lookup goes a step further, explaining potential underlying problems that could trigger the code. This is particularly helpful for unfamiliar codes or for DIY mechanics seeking a deeper understanding beyond just the code definition.
Standout Features: Beyond the Basics
Beyond the essential functions expected of a basic code reader, the Foxwell NT301 boasts several notable and highly satisfying features that elevate it above the ordinary. These are the elements that truly distinguish this code reader and place it in a class of its own.
1. DTC Explanations – No Need for Google
Diagnostic Trouble Codes (DTCs) are inherently technical. Without clear explanations of their meaning and potential causes, DIYers and car owners often remain reliant on mechanics, even with a code reader in hand. The common workaround is using search engines to decipher DTCs. The Foxwell NT301 eliminates this step by instantly providing the meaning as soon as a code is displayed. More impressively, by pressing “ENTER,” the NT301 presents a list of likely causes for that specific DTC. This thoughtful addition sets the NT301 apart in the realm of basic code readers. It’s a feature that should be standard across all code readers, regardless of their complexity.
2. Dedicated Erase Button
While DTC erasing is a standard feature on almost all basic code readers, a dedicated button for this function is surprisingly uncommon. Most require navigating through menus. The NT301’s dedicated erase button offers significant convenience and time savings. Simply highlight the DTCs you want to clear and press the button. This can even be done during brief stops, like waiting at a traffic light.
3. Robust Protective Case
OBD II code readers often endure harsh conditions – accidental drops, handling with greasy hands, and general wear and tear. Consequently, many code readers have a short lifespan, often needing replacement within a few years. The Foxwell NT301 addresses this with a built-in protective case, coated with a soft, yet strong outer layer. This casing effectively absorbs shocks from drops and repels dirt, significantly enhancing the device’s durability. This protective design is a stroke of genius.
4. Satisfying Bouncy Keys
After dealing with vehicle issues, sometimes a bit of tactile satisfaction is needed. The Foxwell NT301’s large, bouncy keys provide just that. They are soft to the touch, depress easily, and rebound with a satisfying bounce. This seemingly minor detail contributes to a surprisingly pleasant user experience and is a subtle reason why I often reach for this code reader when troubleshooting car problems, especially on a less-than-perfect day. It’s a small touch that adds to the overall positive impression.
Vehicle Compatibility: Wide Range, But with Caveats
The Foxwell NT301 exhibits broad compatibility with most post-1996 vehicles I’ve tested. It consistently performs flawlessly, delivering at least 80% of its functions in most cases. However, my testing hasn’t included newer hybrids (including plug-in hybrids), electric vehicles, 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 committing to the NT301.
Limitations: Areas for Improvement
Despite its strengths, the Foxwell NT301 does have limitations. While not deal-breakers, it’s important to be aware of them.
1. No Backlit Keys
Surprisingly, backlit keys are still not a standard feature on many code readers, and the NT301 is no exception. Considering its solid build quality, backlit keys would be a welcome addition, even if it slightly increased the price. The excellent feel and responsiveness of the keys are somewhat diminished by the lack of illumination for use in dimly lit environments.
2. Basic Scanner Functionality
The NT301 is fundamentally a basic code reader. It lacks the capability to scan additional vehicle modules like the transmission or ABS systems. While these modules are generally reliable in well-maintained vehicles, having the option to scan all modules provides peace of mind, ensuring absolutely no hidden issues. This is particularly reassuring when troubleshooting elusive problems where you’re hoping for any diagnostic clue.
3. Cord Length Could Be Longer
Finally, the cord length isn’t the longest in the industry. It’s certainly adequate for use in any vehicle, regardless of seating position. However, after experiencing the longer cord of the Konnwei KW850, which allowed operation from outside the vehicle, a longer cord now feels like a desirable feature. It’s a minor point, but once you’ve experienced the convenience of a longer cord, shorter ones feel slightly restrictive.
Alternatives to the Foxwell NT301
The Foxwell NT301 is a reliable code reader. However, if you prefer a smaller device, one with fewer buttons, or a more pocket-friendly option, alternatives exist.
For a compact glove box scanner, the Ancel AD410 remains a solid choice. It’s been my go-to glove box scanner for over five years with no regrets.
If you seek more advanced features at a budget-friendly price, the TopDon TopScan is worth considering. Despite its small, pocket-sized design, it’s surprisingly powerful, capable of scanning ABS, transmission, and other modules. Furthermore, it’s Bluetooth-enabled, compatible with various vehicles and smartphones.
Final Verdict: Should You Buy the Foxwell NT301?
Absolutely, yes. Without hesitation.
As highlighted in my Foxwell NT201 vs NT 301 comparison, the NT301 is clearly the superior code reader.
While the mentioned limitations are worth considering, they are not deal-breakers for most users. Take a moment to review the cons and decide if they are acceptable for your needs.
