Foxwell NT201 OBD2 Scanner Review: Unboxing and Initial Thoughts
The unboxing of the Foxwell NT201 was a moment of contrasting experiences. My daughter was instantly captivated, grabbing the scanner with pure joy. My reaction was more reserved, a mix of curiosity and slight apprehension about what this brightly colored tool would offer.
The first thing that struck me was the scanner’s vibrant orange hue. While not my preferred color for diagnostic tools (a detail I somehow overlooked on the Amazon page), it certainly made it stand out. The design was compact with rounded edges, a departure from the robust, square designs I usually prefer in my scanners. The keys were flush with the device’s body, another design choice I typically find less tactile and user-friendly compared to raised, distinct buttons. I prefer keys that offer a clear physical feedback, allowing operation without needing to constantly look at the device, unlike modern touch-sensitive interfaces.
While I was internally processing these initial impressions, careful not to dampen my daughter’s enthusiasm, my wife walked in. Her immediate reaction to the NT201 was surprisingly positive: “Finally, a code reader I might actually use!”
Foxwell NT201 OBD2 Scanner – What's in the Box
This comment, combined with my daughter’s excitement, made me reconsider my initial skepticism. Perhaps there was more to the NT201 than met my critical eye. I opened the box, finding a quick start guide and a USB update cable – standard inclusions for a basic OBD2 scanner. Setting aside my usual habit of skipping manuals, I decided to read through the guide, keen to understand what features lay beneath the scanner’s eye-catching exterior.
Core Functions and Capabilities
When evaluating any OBD2 scanner, the core functions and capabilities are paramount. These determine the scanner’s practical value and its ability to assist in diagnosing and resolving vehicle issues. For the Foxwell NT201 OBD2 scanner, the primary functions include:
1. Basic Code Reading and DTC Clearing
Like virtually every OBD2 scanner on the market, the Foxwell NT201 excels at basic code reading and Diagnostic Trouble Code (DTC) clearing. Once connected to a vehicle’s OBD2 port, the NT201 promptly retrieves stored fault codes. These codes can then be further investigated using the DTC lookup feature or cleared if the underlying issue has been resolved. This fundamental capability is essential for any OBD2 scanner, and the NT201 performs this task reliably.
2. Live Data Stream Display
While basic code reading is a standard feature, the ability to display live data is what distinguishes a functional OBD2 scanner from a truly useful one. Live data provides real-time insights into a vehicle’s operational parameters, often revealing issues that might not trigger a fault code or illuminate the check engine light. It is invaluable for diagnosing intermittent problems or narrowing down the root cause of a broader issue indicated by a DTC.
The Foxwell NT201 offers a live data stream function that, while basic, is effective for monitoring essential parameters. A notable feature is its ability to capture live data at the moment a DTC is triggered. Similar to a freeze frame function, this feature records crucial data points such as vehicle speed, coolant temperature, Mass Air Flow (MAF) sensor readings, and fuel trim values when a fault occurs. This real-time data capture is a step beyond standard freeze frame capabilities, providing a more dynamic view of the vehicle’s condition at the time of the fault. This enhanced data logging can be incredibly helpful in diagnosing transient or intermittent issues.
3. Basic DTC Lookup Function
Another valuable feature of the Foxwell NT201 is its integrated DTC lookup library. This feature provides on-device explanations for fault codes, eliminating the immediate need to consult external resources like Google or separate apps. While seemingly basic, many entry-level code readers lack this integrated library, making the diagnostic process less convenient.
However, it’s important to note that the NT201’s DTC library is indeed basic, especially when compared to more advanced scanners like the Foxwell NT301. The NT201 provides a standard, brief definition of the fault code, but it lacks the detailed, step-by-step troubleshooting guidance offered by scanners like the NT301. For DIY mechanics who appreciate more comprehensive support, the NT301’s detailed code definitions, potential causes, and troubleshooting steps are significantly more helpful. For users of the NT201, further research or familiarity with OBD2 codes will likely be necessary to fully understand and address the identified issues, especially for more complex problems.
These are the primary functions of the Foxwell NT201 OBD2 scanner. However, it also includes other notable features that enhance its usability, which are worth considering in this Foxwell NT201 review.

Additional Features of the Foxwell NT201 OBD2 Scanner
To fully appreciate the Foxwell NT201 OBD2 scanner and make an informed purchase decision, it’s crucial to understand its additional features. Beyond the core functionalities, these features contribute to the overall user experience and diagnostic capabilities of the device.
1. Smart Status Indicator Lights
Like many Foxwell scanners, the NT201 includes smart status LEDs that provide immediate visual feedback on the vehicle’s diagnostic status. These indicator lights simplify the scanning process, especially for quick checks.
The NT201 uses a tri-color LED system:
- Green: Indicates no DTCs are present, signaling a system clear of faults.
- Orange: Signals pending DTCs, suggesting potential issues that may develop into more serious faults.
- Red: Indicates current DTCs are present, confirming existing problems that require attention.
These status lights offer a quick, at-a-glance assessment, saving time, especially during routine vehicle checks where a detailed scan might not always be necessary. For mechanics or car owners who perform frequent scans, these lights are a practical feature for efficient diagnostics.
2. Oxygen Sensor (O2 Sensor) Test
The oxygen sensors play a critical role in managing a vehicle’s fuel efficiency and emissions. The upstream O2 sensor, located in the exhaust manifold, monitors the oxygen content in the exhaust gas to ensure optimal air-fuel mixture for combustion. Upstream O2 sensors are crucial for engine performance and fuel economy.
The Foxwell NT201 includes an O2 sensor test function, allowing users to check the functionality of these sensors. This test is valuable because O2 sensors can degrade over time or fail without immediately triggering obvious symptoms, leading to reduced fuel efficiency and increased emissions. By testing the O2 sensors, users can proactively identify and replace failing sensors, maintaining optimal engine performance and reducing environmental impact. This feature adds practical value to the NT201, especially for environmentally conscious users or those keen on maximizing fuel economy.
Foxwell NT201 OBD2 Scanner Vehicle Compatibility
The Foxwell NT201 OBD2 scanner is designed for broad compatibility with most modern vehicles manufactured from 1996 onwards that use the OBD II protocol. This protocol became standard in 1996 in the United States and was gradually adopted worldwide. For owners of mainstream vehicle makes and models, the NT201 is highly likely to be compatible and function effectively.
However, the compatibility of the NT201 has not been explicitly tested with racing cars or exotic vehicles. Owners of such specialized vehicles might need to verify compatibility directly with Foxwell or consult the vehicle’s documentation.
For users uncertain about their vehicle’s compatibility, it’s advisable to contact Foxwell directly. Their customer support can provide specific guidance and confirm whether the NT201 is suitable for a particular vehicle make and model. This proactive step can prevent compatibility issues and ensure the scanner meets the user’s needs.
Foxwell NT201 OBD2 Scanner – Cons
Limitations of the Foxwell NT201 OBD2 Scanner
A balanced and honest review must address not only the strengths but also the weaknesses of a product. This Foxwell NT201 review aims to provide a comprehensive and unbiased assessment, highlighting both the positive and negative aspects of this OBD2 scanner. Transparency about limitations is crucial for potential buyers to make informed decisions. Here are the limitations I observed with the Foxwell NT201:
1. Slow Operation Speed
In situations where time is critical, such as when a vehicle breaks down, the speed of a diagnostic tool is paramount. Unfortunately, the Foxwell NT201 is not particularly fast. Users may find the scanner’s processing speed somewhat sluggish, from the initial loading of modules to completing vehicle scans and displaying results.
The NT201’s slower speed can test the patience of users, particularly in urgent diagnostic scenarios. If speed is a primary concern, especially for professional mechanics or users who frequently diagnose vehicles under pressure, the NT201’s performance might be less than ideal. Users opting for this scanner should be prepared for a more deliberate pace of operation.
2. Lack of AutoVIN Function
The AutoVIN (Automatic Vehicle Identification Number) function is a valuable feature in more advanced OBD2 scanners. AutoVIN automatically retrieves the vehicle identification number when the scanner is connected to the car. This feature serves several important purposes, including quickly identifying the vehicle and ensuring the VIN retrieved electronically matches the physical VIN on the vehicle.
For those purchasing used vehicles, verifying the VIN is crucial as it helps detect potential discrepancies or fraud. The Foxwell NT201, however, does not include the AutoVIN function. This omission means users must manually enter the vehicle information, which is less convenient and slightly increases the time required for initial setup, especially when diagnosing multiple vehicles.
3. Engine Module Focus Only
Modern vehicles are equipped with numerous electronic control modules beyond the engine control unit (ECU), including modules for airbags, transmission, anti-lock braking systems (ABS), and more. The breadth of module access is a significant factor in the comprehensiveness of an OBD2 scanner. Scanners that can access multiple modules provide a more holistic view of the vehicle’s health.
The Foxwell NT201 is limited in its module access, primarily focusing on the engine module. It does not offer diagnostic access to other critical systems like transmission, ABS, or airbags. This limitation means that users seeking to diagnose issues beyond the engine system will find the NT201 inadequate. For comprehensive vehicle diagnostics, particularly for systems beyond engine-related problems, a more advanced, multi-system scanner is necessary. The NT201’s engine-centric focus restricts its utility for users needing broader diagnostic capabilities.
4. Very Basic DTC Library Requiring External Resources
OBD2 scanners rely on Diagnostic Trouble Codes (DTCs) to communicate vehicle faults. To make these codes understandable, manufacturers often include a DTC library that provides explanations. The quality and detail of these libraries vary significantly among scanners. A well-designed DTC library is invaluable for DIY mechanics and car owners to interpret and address vehicle issues effectively.
The Foxwell NT201’s DTC library is notably basic and less informative compared to many other OBD2 scanners, even in the same price range. The library provides a rudimentary definition of the DTC but lacks detailed explanations, potential causes, or troubleshooting steps. Users often need to resort to external resources like Google or dedicated automotive apps to fully understand the meaning and implications of the codes provided by the NT201. This reliance on external lookups adds extra steps to the diagnostic process and can be inconvenient, particularly for users seeking quick and comprehensive code interpretations directly from the device. The basic DTC library is a significant drawback for users who value detailed on-device code information.
