FOXWELL NT201 OBD2 Scanner Engine Code Reader for Cars and Trucks | Reads & Clears Check Engine Light, Live Data, Emissions Readiness

• Read & Clear Check Engine Light: When your dashboard lights up with that check engine light, FOXWELL NT201 puts the answers in your hands. Plug it into your vehicle’s OBD2 Scanner, and within seconds you’ll see exactly what triggered the warning. This engine code reader allows you to read the fault code, understand the issue, and after making repairs, clear the code to turn off the light. No more expensive diagnostic fees at the repair shop—just straightforward information when you need it most.
• One Key Emissions Readiness Check: Worried about passing your state’s smog check or annual inspection? This car scanner takes the guesswork out of the process with a dedicated hotkey for I/M readiness testing. Press it once, and the scanner immediately shows you whether your vehicle’s emission monitors are ready for testing. The color-coded indicator lights (red/yellow/green) give you a clear visual status at a glance—no menu diving, no technical know-how required. Use it before heading to the testing station and avoid the disappointment of being turned away.
• Live Data & Oxygen Sensor Diagnostics: This diagnostic scanner displays live data as you drive or idle, providing insight into your vehicle’s health. Monitor RPM, coolant temperature, intake air temperature, oxygen sensor readings, and other key parameters on the crisp 2.4-inch color screen. Whether tracking down intermittent issues or monitoring engine performance, live data helps you catch small problems before they become costly repairs. The scanner also supports live O2 sensor test mode for vehicles using the CAN protocol, allowing you to analyze exhaust gas oxygen content and evaluate engine efficiency—a valuable vehicle diagnostic tool for fuel mixture and catalytic converter issues.

This car reader diagnostic for all cars is designed specifically for engine and emissions diagnostics. It does not work with electric vehicles, 24V heavy-duty trucks, or non-engine systems such as ABS brakes, airbags, or transmission.
