If you had told me I’d be writing a glowing review of the Foxwell Nt301 Obd2 scanner, I would have been skeptical. Initially, after the NT301 arrived, I wasn’t convinced it would be anything special. My first impression was that it looked bulky, perhaps unnecessarily so, like the Konnwei KW850. I even thought it might just end up as another glove box scanner, similar to my Ancel AD410.
However, my skepticism quickly turned into surprise when I finally plugged the NT301 into my car’s OBD II port and started testing it. To say the Foxwell NT301 exceeded my expectations is an understatement. From initial doubt, I quickly grew to admire this little device, acknowledging its place in my collection of OBD II code readers.
Like any product, the Foxwell NT301 isn’t without its drawbacks, which I’ll address later in this review. These points will provide a balanced perspective, helping you decide if the NT301 is the right OBD2 scanner for your needs or if you should consider other options.
Here’s a quick look at the Foxwell NT301 code reader on Amazon.

Foxwell NT301 OBD2 Scanner Review: First Impressions and Unboxing
As mentioned, I had reservations when the NT301 was on its way. Looking at its dimensions and comparing it to my Ancel AD410, I questioned my decision to even order it. But, deciding to give it a fair chance, I waited for it to arrive.
That spontaneous decision turned out to be a good one. Despite my lukewarm initial impression of the physical unit, plugging it into my car sparked a surprising level of satisfaction.
Holding the NT301, it didn’t feel as bulky as I had anticipated from the dimensions. It was comfortable to hold and operate with one hand. I immediately noticed the keys were soft, responsive, and had a satisfying bounce-back, a feature lacking in 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 further.
The packaging was simple: a transparent plastic clamshell containing the NT301 facing forward, an update cable behind it, and a user manual tucked in between. Nothing extravagant, but functional.
Foxwell NT301 Functions & Abilities
The Foxwell NT301 is a basic OBD2 code reader, designed for fundamental diagnostic tasks. Its strength lies in how effectively it performs these core functions: reading codes and conducting 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 Diagnostic Trouble Codes (DTCs) if any are present and, importantly, provides a brief explanation of their meaning.
For example, the DTC P0113 might be meaningless to the average car owner or DIY mechanic. However, the NT301 clarifies this code as “Intake Air Temperature Sensor 1 Circuit High,” instantly making the issue more understandable and giving you a starting point for troubleshooting.
Clearing codes after repairs is equally simple. There’s a dedicated erase button, or the option is also available within the menu.
2. Dedicated Home Button
A somewhat uncommon but incredibly useful feature on OBD II scanners today is the dedicated HOME button on the Foxwell NT301.
If you need to quickly exit what you’re doing and return to the main menu, there’s no need to fumble through menus or press random buttons. A dedicated HOME button gets you back to the start screen instantly.
This is a time-saving feature, especially valuable in the often-hurried environments of DIY and professional mechanics.
3. Live Data Stream
Live data is crucial for understanding a vehicle’s real-time health. Some problems, like a restricted air intake causing excessive fuel consumption, might not trigger a standard DTC immediately.
Scanning for DTCs alone won’t always reveal these issues. However, examining live data and comparing Mass Air Flow (MAF) sensor readings to expected values can quickly pinpoint the problem area.
This is why a live data function is essential for any useful code reader. Fortunately, the Foxwell NT301 includes this feature, making it a valuable tool for accurate diagnostics.
4. DTC Lookup with Enhanced Information
Adding to its functionality, the NT301 features a DTC lookup function. This is essentially a built-in library where you can enter a code and get its definition.
However, this DTC lookup is more advanced than standard versions. It goes beyond simply defining the code. For unfamiliar codes, or for DIY mechanics still learning, the NT301 provides possible causes for the code, offering deeper insight into the potential problems.
Other Standout Functions & Features
Beyond the expected basic functions of a code reader, the Foxwell NT301 boasts several notable and highly satisfying features that elevate it above the ordinary. These are the features that truly set this code reader apart.
1. DTC Explanations – No Need for Google
DTCs are, by their nature, technical. Without clear explanations, DIYers and car owners are often left relying on mechanics for interpretation, even with a code reader in hand. Many resort to Google or other search engines to decipher codes.
The Foxwell NT301 provides the code definition immediately upon reading a DTC. But it goes further: it also lists potential causes for the DTC when you press ‘ENTER’.
This thoughtful addition makes the NT301 stand out in the basic code reader category. It’s a feature that should be standard across all code readers, regardless of their complexity.
2. Dedicated Erase Button for Convenience
The ability to clear DTCs is a common feature. However, a dedicated button for this is not. Many code readers require navigating through menus to erase codes.
The NT301’s dedicated erase button saves time and adds convenience. Simply highlight the DTCs you want to clear and press the button. This can even be done quickly while waiting at a traffic light.
3. Robust Protective Case
OBD II code readers often endure harsh conditions: accidental drops, greasy hands, and general wear and tear. This rough treatment often leads to a short lifespan.
The Foxwell NT301 is built to withstand this. It features a protective outer case, adding an extra layer of shock absorption and shielding it from dirt. This thoughtful design enhances its durability.
4. Satisfyingly Bouncy Keys
Beyond its functionality, the NT301 offers a surprisingly pleasant tactile experience. The large, bouncy keys are soft to the touch and provide immediate feedback when pressed. They rebound nicely, offering a satisfying click.
This might seem minor, but on a stressful day dealing with car troubles, the tactile feel of the buttons can be a small, welcome comfort. It’s a detail that makes reaching for the NT301 a little more enjoyable.
Foxwell NT301 Vehicle Compatibility
The Foxwell NT301 is compatible with most post-1996 vehicles I’ve tested. It works reliably and delivers a high percentage of its functions across various makes and models.
However, I haven’t tested it with newer hybrids (including plug-in hybrids), electric vehicles, or high-end sports cars. Luxury models like Rolls Royce also remain untested.
If you own these types of vehicles, it’s recommended to contact Foxwell directly to confirm compatibility before purchasing the NT301.
Limitations of the Foxwell NT301
Despite its strengths, the Foxwell NT301 has limitations. These aren’t deal-breakers, but they are worth considering.
1. Non-Backlit Keys
While I haven’t used many code readers with backlit keys, it feels like a missed opportunity on the otherwise well-built NT301. Backlit keys would be particularly useful when using the scanner in dimly lit conditions.
The excellent feel and responsiveness of the keys make the lack of backlighting even more noticeable.
2. Basic Code Reader – Limited Module Scanning
The NT301 is a basic code reader. It doesn’t offer advanced scanning of modules beyond the engine and emissions systems, such as transmission (tranny) or ABS.
While these systems are generally reliable in well-maintained vehicles, the ability to scan all modules provides extra peace of mind, especially when troubleshooting elusive issues.
3. Shorter Cord Length
The NT301’s cable is of adequate length for most vehicles and seating positions. However, compared to scanners like the Konnwei KW850 with its exceptionally long cord, the NT301’s cable feels a bit short.
After experiencing the convenience of a longer cord, it’s something I now appreciate and notice when it’s not there.
Alternatives to the Foxwell NT301
The Foxwell NT301 is a solid OBD2 scanner. However, if you prefer a smaller device, fewer buttons, or a more compact palm-sized option, there are alternatives.
Consider the Ancel AD410 code reader. It has been my trusted glove box scanner for over five years, and I highly recommend it for its portability and basic functionality.
For a more powerful yet still affordable option, look at the TopDon TopScan. This pocket-friendly scanner is surprisingly capable, offering module scanning for ABS, transmission, and other systems.
The TopDon TopScan is also Bluetooth-enabled and compatible with a wide range of vehicles and smartphones.
Should You Buy the Foxwell NT301 OBD2 Scanner?
Yes – absolutely.
As I highlighted in my Foxwell NT201 vs NT301 comparison, the NT301 is a superior tool in its category.
While the limitations mentioned are worth considering, they are not significant drawbacks for most users. Evaluate these points and decide if they are acceptable for your needs.
