Overview
A standalone OBD2 code reader with its own 2.8-inch color screen, built to read and clear check-engine codes, run I/M readiness checks before an emissions test, and graph live sensor data such as RPM, coolant temperature, and fuel trims.
Unlike a phone-paired sensor, the NT301 does its own reading and display, which means no app pairing but also no phone-based history across vehicles. Its readiness hotkeys and red-yellow-green indicator are aimed specifically at smog-check prep, a use case the listing calls out ahead of general diagnostics.
- 2.8 inch color display
- EVAP and O2 sensor testing
- Red-yellow-green smog readiness indicator
- Supports 10,000+ vehicles across OBDII protocols
Who it's for
Owners and DIYers who want a self-contained scanner with a screen, particularly anyone prepping for an emissions or smog inspection who wants to know their I/M readiness status beforehand.
Strengths and trade-offs
Drawn from this product's published specifications.
- Own 2.8-inch screen, no phone pairing needed
- One-click I/M readiness check for smog testing
- Live data graphing for oxygen sensors, RPM, and fuel trims
- Supports all major OBDII protocols
- No phone app for saving history across vehicles
- Advanced modes assume some familiarity with sensor data
Performance notes
It clears a check-engine light only after the underlying fault is resolved, so the code returns if the repair was incomplete, which the listing frames as avoiding a false pass. Beyond basic codes, it runs an EVAP leak check and O2 sensor test, and shows live sensor readings as graphs for spotting an abnormal value in real time.

Yes, it has one-click I/M readiness hotkeys with a red-yellow-green indicator for that purpose.
Does the NT301 need a phone or app?
