FOXWELL NT301 OBD2 Scanner Code Reader – 2.8" Color Display, Live Data & I/M Readiness

Designed for DIYers, home mechanics, and small shops, the FOXWELL NT301 pairs simple operation with advanced diagnostic features. Plug it into the 16-pin DLC under the dash, power the ignition, and the unit instantly reports Diagnostic Trouble Codes (DTCs), I/M readiness status, and live sensor graphs. Its bright 2.8" color display and one-touch menu make interpretation straightforward, while support for multiple OBDII protocols covers most 1996+ gasoline cars and many newer models from Europe and Asia.

How quickly will the NT301 identify a check engine light issue?

The NT301 reads stored, pending, and permanent DTCs within seconds after connecting to the vehicle. The tool decodes the numeric fault into plain language so you can understand the affected system without needing technical manuals.

• Instant DTC readout and plain-English descriptions
• One-touch code clear after confirmed repair
• Displays MIL status and freeze frame data for context

Can the NT301 help me pass emissions and inspection tests?

The scanner includes dedicated I/M readiness checks and a visible Red–Yellow–Green LED indicator so you can verify monitor status before the test center visit. Built-in audio feedback and one-key readiness reports reduce guesswork on inspection day.

• I/M readiness hotkeys for quick pass/fail checks
• LED indicator shows overall readiness at a glance
• Helps identify incomplete monitors that could cause test failure

What advanced diagnostics does this reader offer beyond basic code clearing?

Beyond reading and erasing codes, the NT301 supports O2 sensor testing, EVAP leak checks, and live data graphing to pinpoint performance issues. Logged live parameters—like RPM, fuel trims, and coolant temp—help you spot abnormal behavior in real time for smarter troubleshooting.

• O2 sensor and EVAP system checks for emissions-related faults
• Live data streaming and graphing for trend analysis
• Data logging for review and comparison after repairs

Which vehicles are compatible and what does setup require?

The NT301 supports all common OBDII protocols (CAN, ISO9141, J1850, KWP2000, etc.) and works with most 1996+ gasoline vehicles plus many 2000+ European and Asian models; some 12V diesels are supported where OBDII is present. No batteries, charging, or software subscriptions are needed—just plug in and power on.

• Supports KWP2000, J1850 VPW/PWM, ISO9141, and CAN protocols
• Compatible with most 1996+ gasoline cars and many newer models
• Lifetime free updates, plug-and-play operation, no subscription
