It all started when my young daughter, with her keen eye for bright objects, pointed at a vibrant orange OBD II code reader on Amazon. I was casually browsing, searching for the next tool to simplify my DIY auto repairs, which have become a side passion of mine. That simple moment sparked the idea for this Foxwell Nt201 Obd2 review, and it happened much sooner than I had anticipated.
You see, my daughter has a knack for spotting details and things that stand out. So, when she interrupted my scrolling to point at the shiny, orange OBD II code reader, I had no choice but to stop and listen to her curiosity.
Despite already owning a collection of OBD II code readers, the eye-catching NT201 soon found its way to our doorstep. The anticipation was palpable, especially for my daughter, who repeatedly asked when “her scanner” would arrive.
Answering her questions truthfully became a challenge, and like any parent of young children, I resorted to mixing facts with a little bit of fiction to manage her excitement. How I managed to keep her patience during the waiting period remains a blur, but finally, the awaited day arrived. Unboxing time – her favorite part of my auto DIY endeavors – was upon us.
Before diving into the unboxing and initial impressions, here’s a glimpse of what the Foxwell NT201 code reader looks like on Amazon.

Foxwell NT201 Review: First Impression and What’s in the Box
When the package was finally unboxed, my daughter and I experienced different realities. She excitedly grabbed the bright orange code reader and jumped around, while I quietly assessed what had just arrived.
The code reader was indeed a striking orange – a color I personally dislike (somehow, I missed this detail on the Amazon product page).
The unit felt small and didn’t quite align with my preferred scanner design. It featured rounded edges instead of the sturdy, square edges I’ve grown to appreciate in my diagnostic tools.
Furthermore, the keys were flush with the device’s surface – another design choice I’m not fond of. I prefer keys that are distinct and contrasting, allowing me to physically feel each press without needing to look, unlike using a modern touchscreen phone.
While I contemplated these initial impressions, trying not to dampen my daughter’s enthusiasm, my wife walked in. After a quick glance at the code reader, she declared, “Finally, a code reader I’ll actually use!”
I looked at both of them and smiled for the first time since opening the box. If they both saw something appealing, perhaps I was missing something.
I then turned my attention to the recyclable packaging and explored the contents: a quick start guide and a USB update cable. After setting aside the owner’s manual, I began to read through it, something I would typically skip.
Functions & Abilities
The functions and capabilities of an OBD II code reader are always my primary focus when evaluating these tools. Understanding these aspects provides an immediate perspective on what to expect from the device.
For the Foxwell NT201 OBD2 scanner, here are its core functions and abilities:
1. Basic Code Reading & DTC Erasure
Like virtually every OBD2 code reader available today, the Foxwell NT201 offers basic diagnostic trouble code (DTC) reading and erasure.
When connected to a vehicle’s OBD II port, the NT201 easily retrieves stored fault codes. These codes can then be further investigated using the DTC Lookup function or cleared if the underlying issue has been resolved.
This fundamental function is essential for any code reader, and the NT201 performs it reliably without any issues. It’s a basic but crucial starting point for automotive diagnostics.
2. Ability to Display Live Data
While basic code reading and DTC clearing are foundational, the true value of a basic OBD2 code reader lies in its ability to display live data. This feature takes diagnostics a step beyond simply reading stored codes.
Live data streams are often instrumental in identifying intermittent vehicle problems that may not trigger a fault code immediately. Furthermore, live data can help pinpoint the root cause of broader issues flagged by DTCs, offering real-time insights into engine performance.
The Foxwell NT201 OBD2 scanner includes a live data display function that, while basic, is effective. Interestingly, this live data can be accessed not only during active diagnosis but also when a DTC occurs. Similar to a traditional freeze frame function, this option allows the system to record parameters like vehicle speed, coolant temperature, MAF sensor readings, and fuel trims when a fault is detected. This provides more comprehensive data logging than a standard freeze frame feature typically offers.
You could consider it enhanced data recording with added value.
3. Basic DTC Lookup
Another noteworthy feature of the Foxwell NT201 is its integrated DTC library or lookup function. This acts as a “library of explanations,” interpreting the technical jargon presented by the code reader, particularly for unfamiliar codes.
Despite being a basic feature, many code readers lack this capability, forcing users to rely on external resources like Google or specialized software – which can be inconvenient.
However, it’s important to remember that the NT201’s DTC library is basic and not as comprehensive as what you’d find in more advanced tools like the Foxwell NT301.
With the NT201, you receive a standard definition of the fault code, but further investigation and troubleshooting are often required. In contrast, the Foxwell NT301 offers more detailed code definitions, including potential causes and even troubleshooting steps – invaluable information for the DIY mechanic. This level of detail is particularly beneficial for those new to auto DIY repair.
These are the primary functions and abilities of the Foxwell NT201 OBD2 scanner. However, there are additional noteworthy features that deserve mention in this review.
Other Notable Functions & Features
To fully understand the Foxwell NT201 and make a well-informed purchase decision, it’s crucial to consider all of its features. This review now delves into these additional aspects.
Beyond the core functions already discussed, here are some other notable features worth considering when thinking about buying the NT201.
1. Smart Status Lights
Like many Foxwell scanners and code readers, the NT201 incorporates smart status lights to provide immediate feedback once connected to a vehicle.
These three indicator lights – red, orange, and green – quickly communicate the vehicle’s diagnostic status. Green indicates no current DTCs, orange signifies pending DTCs, and red signals the presence of active DTCs.
For users who are busy or prefer quick assessments, these lights are incredibly convenient. A green light provides immediate reassurance, orange suggests a potential issue requiring further investigation, and red clearly indicates a problem needing attention.
This simple yet effective feature saves time, especially during routine vehicle scans when no check engine light is illuminated. It’s a feature that brings a sense of ease and efficiency to the diagnostic process.
2. O2 Sensor Test
The upstream O2 sensor in a vehicle’s engine plays a vital role in providing oxygen data to the ECU. This data is crucial for optimizing fuel efficiency based on current driving conditions.
Unfortunately, due to their location under the vehicle and demanding operating environment, O2 sensors are prone to failure and often require replacement without the vehicle owner’s immediate awareness.
The Foxwell NT201 includes an O2 sensor test function. This feature allows users to check the sensor’s performance, helping ensure optimal fuel economy and minimize harmful exhaust emissions.
This is a valuable feature that contributes to both vehicle efficiency and environmental responsibility.
Foxwell NT201 Vehicle Compatibility
As a basic OBD2 code reader, the Foxwell NT201 boasts broad compatibility with most modern vehicles manufactured after 1996 that utilize the OBD II diagnostic protocol.
This means that if you drive a common make and model, there’s a high likelihood that the NT201 will work seamlessly with your vehicle. Its compatibility covers a wide range of passenger cars, SUVs, and light trucks adhering to OBD2 standards.
The only vehicle types not explicitly tested for compatibility are racing cars and exotic vehicles. For these specialized vehicles, compatibility may vary.
If you have any doubts about the NT201’s suitability for your specific vehicle, it’s recommended to contact Foxwell directly. Their support team can provide accurate compatibility information and address any concerns you may have.
Limitations
A thorough and honest review should present a balanced perspective, highlighting both the strengths and weaknesses of a product.
This Foxwell NT201 review aims to provide a comprehensive and unbiased assessment, leaving no aspect unexplored to give you a clear understanding of the code reader’s capabilities and limitations.
Here are the limitations I observed during my evaluation:
1. The Code Reader Is Slow
When faced with a vehicle breakdown and the urgency to diagnose the issue, a slow code reader can be incredibly frustrating.
Unfortunately, the Foxwell NT201 OBD2 scanner is not particularly fast. From the initial loading of its various modules to completing a vehicle scan and displaying results, the process can feel sluggish.
If you choose the NT201, patience is definitely required. Be prepared for a slower diagnostic process, even when under pressure to quickly identify a problem.
2. No AutoVIN Function
The AutoVIN function automatically retrieves the Vehicle Identification Number (VIN) when a code reader is connected to a vehicle. This feature is incredibly useful for quickly identifying the vehicle and ensuring data accuracy.
A key benefit of AutoVIN is verifying that the VIN retrieved by the scanner matches the VIN on the vehicle itself. This is particularly important when inspecting used vehicles, as it helps detect potential VIN discrepancies or fraudulent activities.
Regrettably, the Foxwell NT201 lacks this AutoVIN feature. Manually entering the VIN may be necessary for certain functions, adding an extra step to the diagnostic process.
3. Engine Module Scans Only
Modern vehicles are composed of various electronic control modules (ECMs) beyond just the engine module, including systems like airbags, transmission, ABS, and anti-theft.
The more modules a scanner can access, the more comprehensive its diagnostic capabilities. Full system scans provide a holistic view of the vehicle’s health.
However, the Foxwell NT201 is limited to scanning only the engine module. It cannot access or diagnose issues within other vehicle systems like the transmission, ABS, or airbags.
If you need to diagnose problems beyond the engine or require deeper diagnostics such as bi-directional tests for other modules, the NT201’s capabilities will be restricted to engine-related codes and data.
4. Very Basic DTC Library: Google Needed
Diagnostic Trouble Codes (DTCs) are numerous, encompassing both generic and manufacturer-specific codes. Understanding these codes is crucial for accurate diagnosis.
OBD2 code reader manufacturers typically include a DTC library to explain these codes in a user-friendly manner. More advanced libraries provide detailed explanations, potential causes, and even troubleshooting steps.
However, the Foxwell NT201’s DTC library is very basic, arguably one of the most limited I’ve encountered recently.
The library presents the code definitions with minimal explanation, leaving users to decipher the meaning and determine the next steps. It lacks detailed descriptions, potential causes, or troubleshooting guidance.
If you are unfamiliar with a particular DTC, relying on external resources like Google or dedicated automotive diagnostic apps will be necessary to gain a more complete understanding of the issue and how to resolve it.
