Automotive TPMS Reset & Sensor Relearn Tool for GM Vehicles (315/433 MHz)

Product Overview

The OBDResource EL50448 TPMS Relearn Tool is a dedicated diagnostic device designed to activate and relearn tire pressure monitoring system (TPMS) sensors on most General Motors (GM) vehicles, including Chevy, Buick, GMC, and Cadillac series models from 2006 to 2025. This essential tool helps reset tire pressure alarms, relearn TPMS sensor positions after rotation or sensor replacement, and maintain the proper operation of the TPMS system without visiting a dealer.


Key Features

Quick and Easy TPMS Sensor Relearn

The EL50448 tool simplifies the TPMS relearn process into easy steps. After entering the vehicle’s TPMS Learn Mode, hold the tool near the valve stem to instantly read and activate the tire pressure sensor.

Meh

It worked for my first wheel multiple times but not the second so I can not continue to teach my car the tire pressure sensors without letting air out and refilling them.

easy peasy

simply put the 9 volt battery in the unit, put the car into "learning TPMS mode" and walked around the car, pushing the button at each tire, starting at drivers side front, then passenger front, etc. Worked like a charm

Works great!

Worked great for setting TPMS on my 2017 chevy silverado. It took a few tries to get it aimed right, and I almost gave up, but eventually got them all synced through the tire sidewalls. Good product!

Handy tool to reset TPMS

I have two cars that are still displaying TPMS warnings, even though I have manually measured tire pressures and they are OK. Hope this resets them appropriately so I can go back to relying on the system to keep track of my tire pressures.

It works!

Works on my 2018 Suburban Premier.Do not follow the instructions it comes with. They are generic. Follow your manual instructions. Took me about 10 minutes. Had to find the sweet spot on my wheels. Mine were inline with valve stem where tire and wheel meet. Also, it was a 2 second hold of button, not just a press like instructions supplied indicated. Once I figured the sweet spot and 2 second hold, done in 1 minute. Good luck.

Full Send, works as discribed

First...I read in other reviews that some had issues connecting to the sensors. If you simply follow the directions there is no reason why this process would take you longer than 60 secs. This product does exactly what it says for GM vehicles. You will need to know how to get your vehicle into "learn mode" but as long as you know that, it's a breeze.

Easy to use Tire Pressure Sensor learn tool for GM vehicles

The EL-50448 TPMS Reset Tool for GM Series Vehicles is easy to use, and it works! What more is there to say? After rotating the tires on my 2016 Malibu, I was able to relearn all four TPM sensors in less than two minutes. If you want an inexpensive, easy to use TPMS tool for your GM vehicle, this is the one to buy.Step 1. Insert 9 volt battery (not supplied)Step 2. Place vehicle in TPMS Learn mode (check Owner's Manual)Step 3. Starting at left front tire (driver's side), place the end of the "antenna" on the tire sidewall next to the edge of the wheel (NOT on the wheel), press and hold the button. The green "TX" LED will illuminate. After 5-10 seconds the horn will chirp to indicate that TPM sensor is learned. Release the button.Step 4. Move clockwise around the vehicle (R/F, R/R, L/R) and repeat Step 3 to learn the other three sensors. After the last TPM sensor is learned, the vehicle will exit TPMS Learn mode.
