FOXWELL NT301 Plus

Overview

The FOXWELL NT301 is a step up from basic code readers, adding live data graphs, battery voltage tests, and a durable case for home mechanics.

Whether you are troubleshooting a check engine light, preparing for an emissions test, or performing scheduled maintenance, the NT301 Plus gives you the module access and service functions you need without booking a dealer appointment. On-screen menus walk you through each step, and stored scan reports help you track repairs over time.

Key Features

• Read/clear engine codes with live data graphing
• Smog readiness (I/M monitors) and freeze frame data
• Built-in battery voltage test
• Includes protective storage case
• DTC lookup library on device

What You Can Diagnose

The NT301 Plus helps you identify root causes faster by reading fault codes, live sensor values, and module status across the systems it supports:

• Check engine light (MIL) and powertrain fault codes
• Oxygen sensor, fuel trim, and emissions-related DTCs
• Evaporative emissions (EVAP) system faults
• Catalyst efficiency and misfire monitor status
• Freeze frame data captured at the moment of failure

How to Use This Tool

Plug the NT301 Plus into your vehicle's 16-pin OBD2 port (usually under the dashboard). Turn the ignition to ON — the tool powers from the vehicle and guides you through reading codes in seconds. Use the built-in DTC library to understand each fault, then clear codes after repairs and re-scan to confirm the fix.

Vehicle Compatibility

1996+ OBD2 gasoline and light-duty vehicles with a 16-pin DLC. Covers engine and emissions systems only — not ABS, airbag, or bidirectional active tests.

Always verify that your exact year, make, model, and engine combination is supported before purchase — especially for service resets, bi-directional tests, and brand-specific modules. OBD2 port location is typically under the driver-side dashboard on U.S. vehicles from 1996 onward.

Who Should Buy This

Home mechanics and DIYers who want more than a basic code reader without paying for full-system coverage.

If you regularly work on your own vehicles, run a small repair shop, or buy used cars to flip, the NT301 Plus pays for itself quickly compared to per-visit dealer diagnostics.
