Made in Mainland China.

Why You'll Love This Tool

• 2-in-1 Functionality: Combines a TPMS sensor relearn tool with a full-range digital tire pressure gauge — no need for two separate devices.
• Broad Vehicle Compatibility: Works on most General Motors vehicles (Chevrolet, Buick, GMC, Opel, Cadillac, and more) equipped with 315 MHz or 433 MHz TPMS sensors — equivalent to the EL-50448.
• Accurate Digital Readings: Instantly displays tire pressure in PSI, BAR, KPA, or Kg/cm² with readings accurate to 0.05 increments. Range: 0–150 PSI / 0–7 Bar / 0–700 KPA / 0–7 Kgf/cm².
• Auto-Reset Gauge: The gauge automatically resets when you take a new pressure reading — no manual calibration needed.
• Works on All Tires: Compatible with cars, motorcycles, and bicycles.
• Battery Saving Auto Shut-Off: Automatically powers off after 30 seconds of inactivity to preserve battery life. Features a replaceable 9V battery (not included) and a manual power switch.
• Bleed Off Excess Air: Allows you to release over-inflated air directly through the valve — all in one step.

How to Use the TPMS Reset Function (3 Easy Steps)

1. Place your vehicle in TPMS Learn Mode (refer to your owner's manual).
2. Hold the right antenna firmly against the sidewall of the tire, close to the valve stem.
3. Press and hold the right button while the tool is against the tire sidewall. Repeat for each tire.

How to Use the Tire Pressure Gauge

Place the left head directly on the valve stem. The digital display will instantly show the current pressure and holds the reading on screen even after you remove the tool — so you can read it at your own pace. Switch between PSI, BAR, KPA, and Kgf/cm² by pressing the left button before reading.

Save Money — Do It Yourself

Every time your TPMS light triggers after a tire rotation or replacement, dealers charge $50–$100 just to reset the sensors. This tool pays for itself after just one use. Properly inflated tires also improve fuel economy, handling, and tire longevity — learn more from the National Highway Traffic Safety Administration about TPMS requirements.
