A rugged handheld code reader that graphs live engine data and reads the codes that put your check-engine light on - no phone or app required.
When the check-engine light comes on, you want to know what is actually wrong before you start throwing parts at it. The FOXWELL NT301 plugs into the 16-pin OBD2 port on any 1996-or-newer car, light truck, or SUV and pulls the stored trouble codes in seconds. It shows you the code, tells you what it means in plain language on a 2.8-inch color screen, and lets you clear it once the repair is done. No laptop, no phone, no app, no subscription - just plug in and read.
What sets it apart from a bargain-bin reader is the live data. You can watch oxygen sensors, fuel trims, coolant temperature, and RPM update in real time and view them as a graph, so an intermittent problem that only shows up under load is a lot easier to catch. Dedicated I/M readiness buttons and a red-yellow-green LED tell you at a glance whether the vehicle will pass an emissions test, and the built-in EVAP and O2 sensor tests help you track down leaks and lean or rich conditions. It is a straightforward, well-built tool that reads and clears generic engine codes - note that it does not cover ABS, SRS, or transmission-specific modules, so it is best paired with a full-system scanner when you need those. Ships from the USA.
