  • Read & Clear Check Engine Light: When your dashboard lights up with that check engine light, FOXWELL NT201 puts the answers in your hands. Plug it into your vehicle's OBD2 Scanner, and within seconds you'll see exactly what triggered the warning. This engine code reader allows you to read the fault code, understand the issue, and after making repairs, clear the code to turn off the light. No more expensive diagnostic fees at the repair shop - just straightforward information when you need it most.
  • One Key Emissions Readiness Check: Worried about passing your state's smog check or annual inspection? This car scanner takes the guesswork out of the process with a dedicated hotkey for I/M readiness testing. Press it once, and the scanner immediately shows you whether your vehicle's emission monitors are ready for testing. The color-coded indicator lights (red/yellow/green) give you a clear visual status at a glance - no menu diving, no technical know - how required. Use it before heading to the testing station and avoid the disappointment of being turned away.
  • Live Data: This diagnostic scanner displays live data as you drive or idle, providing insight into your vehicle's health. Monitor RPM, coolant temperature, intake air temperature, oxygen sensor readings, and other key parameters on the crisp 2.4-inch color screen. Whether tracking down intermittent issues or monitoring engine performance, live data helps you catch small problems before they become costly repairs.
  • O2 Sensor Monitoring Test: Check if you're wasting fuel. The oxygen sensor tells the engine how much fuel to burn. When it ages or becomes sluggish, its feedback turns inaccurate, and your vehicle will quietly consume extra fuel. The FOXWELL NT201 lets you view real-time oxygen sensor data. Instantly check whether the sensor responds quickly enough and if the air-fuel mixture stays at the ideal state. Fast signal response means efficient combustion and better fuel mileage. Flat or slow signal readings indicate fuel waste. Detect issues early, save more money and extend your vehicle's driving range.

Description

Lowest Cost Solutions for 90% Common Repair Problems Self-check engine issues and smog test, avoid unnecessary maintenance or overcharging. Display vehicle information, such as VIN, CID, CVN, and etc., offers convenience for users and improves diagnostic accuracy and efficiency Provides instant code definitions and clues for your reference to begin car troubleshooting in the right direction. Supports review, record, and playback data. Store and transfer diagnostic report to your phone/computer for fast analysis Will the scanner work on my car? How do I know if it’s compatible? FOXWELL NT201 is compatible with all OBD-II compliant cars and light trucks, gasoline vehicles since 1996 and diesel vehicles since 2008. If your car has the standard 16-pin OBD-II port, it will work. Do I need to update it? Does it come with free updates? No updates are required. Unlike some advanced scanners, NT201 is designed to be fully functional out of the box. There’s no need for software downloads or subscriptions. Just plug it in and start scanning. (We also provide lifetime free update.) Can I just clear the codes to turn off the Check Engine Light? It's only recommended after repairing the problem. Simply erasing the code without fixing the cause will make the light come back, often quickly. When should I avoid clearing the codes right away? If you haven’t diagnosed or fixed the issue, it’s better to read and record the codes first and leave them active. This helps your mechanic (or you) diagnose the problem. Should I drive the car after repairs before clearing the code? Yes. Many mechanics recommend fix first, then test drive to confirm the problem is gone. The car’s system may reset the light on its own if the fault no longer exists. If not, you can manually clear it with the scanner.

I can't see anyone needing more than this unless you are working on extremely complex systems.
I received the device on time. My usb cable was a charging cord so I had to purchase a Data transfer cord. With the correct cord I was able to update the scanner to the latest version. I scanned my Subaru properly and gave me the information I needed to clear the codes and get the car back on the road. Function is excellent Connectivity is correct Installation is easy It has all the features I need. and the size is easy to work with. provodes live data. ... show more

Work well
Just what I needed
Reviewed in the United States on September 5, 2026 by Gary Davenport

Does work for the price, but doesn't work for all codes.
Works well enough for me, but not for all codes. I'm not a mechanic, so it does what it does for the price.
