If you had told me I’d be writing a Foxwell Nt301 Diagnostic Scan Tool Review with genuine enthusiasm, I would have been skeptical. Initially, after ordering the NT301, I had my doubts, wondering if it would truly be worth my time, especially considering its seemingly bulky size compared to other code readers on the market.
My first impression upon receiving the package wasn’t overwhelmingly positive. The NT301 appeared larger than I anticipated, bringing to mind the Konnwei KW850 in terms of size. I even relegated it in my mind to potentially just becoming a larger version of my glove box scanner, the Ancel AD410, which I was already quite satisfied with.
However, my lukewarm expectations were completely overturned the moment I plugged the Foxwell NT301 into my car’s OBD II port and started testing. This diagnostic scan tool turned out to be a genuine surprise, earning the title of the ‘queen of OBD surprises’ in my book. My initial apprehension quickly transformed into admiration, recognizing the value and effectiveness it brings to the table, even within my collection of OBD II code readers.
That being said, like any product available, the Foxwell NT301 isn’t without its drawbacks, which I’ll address later in this nt301 diagnostic scan tool review. These points will offer a balanced perspective, helping you determine if this code reader is the right choice for your OBD II diagnostic needs, or if you should consider other options.

First Impressions: Unboxing and Handling
As mentioned, I approached the arrival of the NT301 with mixed feelings. Comparing its dimensions to my existing Ancel AD410, I questioned my decision to order it. Yet, curiosity prevailed, and I allowed the order to proceed.
This spontaneous decision proved wise when, despite my initial unimpressed reaction to its physical appearance, plugging the code reader into my vehicle ignited a sense of pleasant surprise. It was a moment of automotive tech infatuation!
Holding the unit, I realized it wasn’t as cumbersome as the dimensions suggested. It fit comfortably in one hand, allowing for easy operation. Immediately, I noticed the keys – soft, responsive, and with a satisfying bounce-back action, a tactile improvement over the Ancel AD410 I was using as a benchmark.
The color display and the overall feel of the code reader in my hands instantly shifted my perception. My initial reservations vanished, replaced by anticipation to explore its full functionality. The packaging itself was straightforward: a transparent clamshell case showcasing the NT301, an update cable tucked behind, and the user manual completing the set.
Key Functions and Capabilities of the NT301
The Foxwell NT301 is recognized as a basic code reader, focusing on fundamental OBD II diagnostic tasks. Its strength lies in how effectively it executes these core functions: code reading and OBD II system diagnosis. So, what did I discover when I put it to work?
1. Basic Code Reading and DTC Erasure
Connecting the Foxwell NT301 to a working OBDII port is seamless. It quickly retrieves OBD II error codes, if present, and importantly, provides a concise explanation of their meaning. For instance, the code P0113 might be cryptic to many car owners or DIY mechanics. However, the NT301 clarifies it with the description: Intake Air Temperature Sensor 1 Circuit High. This instant explanation demystifies the code, offering a clear starting point for understanding potential issues.
Need to clear codes after completing a repair? The NT301 simplifies this process with a dedicated button or through an easily accessible menu option.
2. Dedicated Home Button
A unique and surprisingly rare feature on modern OBD II scanners is the Foxwell NT301’s dedicated home button. If you need to quickly exit a function and return to the main menu, there’s no need to fumble through multiple presses. A single press of the ‘home’ button instantly resets the system, taking you back to the starting screen. This feature is a valuable time-saver, especially in busy garage environments for both DIYers and professional mechanics.
3. Live Data Streaming
Live data is crucial for understanding a vehicle’s real-time health. Some intermittent issues, like a partially blocked air intake leading to inefficient fuel consumption, may not trigger a standard DTC code immediately. Relying solely on standard scans might miss these subtle problems.
However, by accessing live data and comparing sensor readings, such as MAF sensor values, against expected parameters, you can quickly pinpoint anomalies. This capability is why I consider live data functionality a minimum requirement for any useful code reader. Fortunately, the Foxwell NT301 includes this feature, proving invaluable for in-depth diagnostics.
4. Advanced DTC Lookup
Adding to its functionality, the NT301 features a DTC lookup function, essentially a built-in library of Diagnostic Trouble Codes. By entering a code and pressing ‘ENTER’, you receive its definition. However, this DTC lookup goes beyond simple definitions. It provides potential causes and related issues that could trigger the code. This advanced approach helps users, especially those less familiar with DTCs, to not only understand the error code but also the possible underlying problems.
Standout Features That Set the NT301 Apart
Beyond the standard functions of a basic code reader, the Foxwell NT301 offers several notable and satisfying features that elevate it above the ordinary. These features are what truly distinguish this diagnostic scan tool and place it in a class of its own.
1. DTC Explanations On-Screen, No Google Needed
DTCs, by their nature, are technical. Without a clear explanation of their meaning and potential implications, DIYers and car owners might still find themselves reliant on mechanics, even with a code reader in hand. Traditionally, users often resort to search engines like Google to decipher codes.
The Foxwell NT301 preempts this by providing code definitions immediately upon reading them. But it goes further: by pressing ‘ENTER’ on a highlighted DTC, the NT301 displays a list of potential causes that could trigger that specific code. This thoughtful and intelligent feature sets the NT301 apart from other basic code readers. It’s a feature I believe should be standard in all code readers, regardless of their complexity.
2. Dedicated Erase Button for Quick Code Clearing
While DTC erasure is a standard feature on most basic code readers, the Foxwell NT301 stands out by including a dedicated button for this function. This eliminates the need to navigate through menus to clear codes. This dedicated button offers real convenience and saves time. Simply select the DTCs you wish to clear and press the button – the codes are gone. This can even be done during short stops, like waiting at a traffic light.
3. Robust Protective Case for Durability
OBD II code readers often endure harsh conditions – accidental drops, handling with greasy hands, and general wear and tear. This rough treatment can shorten the lifespan of many scanners, with some failing within a year and many retired after a few years due to damage.
The Foxwell NT301 addresses this with a built-in protective case, featuring an outer coating over its standard casing. This soft yet strong layer cushions against impacts from drops and repels dirt, protecting the code reader’s body directly. This design choice is simply genius for longevity.
4. Nice, Large, Bouncy Keys for User Satisfaction
Sometimes, after dealing with car troubles, a bit of tactile satisfaction is welcome. The Foxwell NT301’s keys provide just that. They are large, soft to the touch, and depress easily, offering a pleasant tactile feedback. Upon release, the keys bounce back in a satisfying manner. It might seem minor, but this detail enhances the overall user experience. On days when dealing with frustrating vehicle issues, the NT301’s keys offer a small, but noticeable, positive interaction.
Foxwell NT301 Vehicle Compatibility
The Foxwell NT301 exhibits broad compatibility with most vehicles manufactured post-1996 that I’ve tested. It operates flawlessly, consistently delivering a high percentage of its functions, typically over 80%.
However, my testing has not included newer hybrid vehicles (including plug-in hybrids), electric cars, sports cars, or luxury brands like Rolls Royce. If you own one of these vehicle types, it’s advisable to directly contact Foxwell to confirm compatibility with your specific make and model before committing to this code reader.
Limitations
Despite its many positives, the Foxwell NT301, like any product, has limitations. While these haven’t been deal-breakers for me, it’s important to be aware of them.
1. The Keys Aren’t Backlit
While I haven’t personally used a backlit code reader yet and they might be uncommon at this price point, considering the robust build of the NT301, backlit keys would be a valuable addition, even if it slightly increased the cost. The excellent feel and responsiveness of the keys are somewhat diminished by the lack of backlighting, especially when using the scanner in dimly lit conditions.
2. The NT301 is a Basic Code Reader in Functionality
Beyond the lack of backlit keys, the NT301 is fundamentally a basic code reader. It doesn’t offer advanced module scanning capabilities for systems like the transmission or ABS. While these systems are generally reliable in well-maintained vehicles, the ability to scan all modules provides a sense of thoroughness and reassurance that everything is in order. This is particularly useful when troubleshooting elusive issues where you’re hoping for any diagnostic clue.
3. The Cord Isn’t the Longest
Lastly, the NT301’s cable isn’t the longest available on the market. It’s certainly adequate for use in any vehicle and from any driver’s seat position. However, after experiencing the extended reach of the Konnwei KW850’s longer cable, which allowed for operation outside the vehicle, the NT301’s cable feels somewhat restrictive in comparison. While functional, the shorter cable is a minor point to consider if extra reach is a priority.
Alternatives to Consider
The Foxwell NT301 is a reliable code reader. However, it might not be ideal if you prefer a smaller device, one with fewer buttons, or a more pocket-friendly option.
If you prioritize a compact size, the Ancel AD410 code reader remains my recommended glove box scanner for over five years, and I’m consistently satisfied with its performance for basic needs.
For those seeking more advanced capabilities without a significant price increase, the TopDon TopScan is worth considering. It’s a small, pocket-sized scanner but surprisingly powerful, capable of scanning ABS, transmission, and other modules. Furthermore, it’s Bluetooth-enabled and compatible with a wide range of vehicles and smartphones.
Final Verdict: Should You Buy the Foxwell NT301?
Yes – absolutely. As highlighted in my Foxwell NT201 vs NT301 comparison, the NT301 is clearly the superior choice.
While the mentioned limitations are worth noting, they aren’t significant drawbacks for most users needing a dependable basic OBDII scanner. Consider these points and decide if they are factors you can accept for your diagnostic needs.
