FOXWELL NT301 OBD2 Scanner — Professional OBDII Code Reader with 2.8" Colour Screen, Live Data & I/M Readiness

FOXWELL NT301 is a plug-and-play OBD2 code reader that reads, clears, and graphs engine diagnostics so you can identify check engine issues fast.

The FOXWELL NT301 OBD2 scanner is a compact professional-grade diagnostic tool designed for DIYers and technicians who want clear, reliable engine data without a complicated interface. Plug it into your vehicle’s 16-pin DLC, power the ignition, and the unit reads Diagnostic Trouble Codes (DTCs), shows live data, and helps confirm emissions readiness. Its color display, one-click I/M readiness check, and live-graphing make it useful for pre-inspection checks, troubleshooting fuel and sensor problems, and verifying repairs after maintenance.

How quickly can I read and clear a check engine light?

The NT301 retrieves stored, pending, and permanent engine codes within seconds of connecting to the vehicle. It also offers safe code clearing: the device will only remove the check engine indicator after the underlying code is no longer present, preventing false passes.

• Instant code read and description on the 2.8" color screen
• One-click erase function once faults are resolved
• Keeps permanent codes until the vehicle confirms repair
• Speaker feedback and on-screen results for quick verification

What live data and tests can this scanner run?

NT301 displays live sensor values and plots them as graphs so you can observe trends and spot anomalies. It supports enhanced OBDII tests including O2 sensor diagnostics and EVAP system checks for more meaningful troubleshooting than basic readers.

• Real-time graphs for RPM, coolant temp, fuel trims, oxygen sensors
• O2 sensor and EVAP system test modes for emissions-related faults
• Data logging to review values over time and after repairs
• Red-yellow-green LED I/M readiness indicator for quick pass/fail checks

It’s especially useful for drivers who want instant, actionable information about engine faults without needing a shop visit, while still providing the expanded tests and live-data graphs that pros expect from a compact diagnostic tool.
