GM TPMS Reset: The Trick to Relearning Sensors Fast

Tire pressure (TPMS) light on? Need to relearn or reset your GM TPMS sensors? Installed new sensors and need to program them to your vehicle? Flat tires not registering with TPMS? In this video, I show how to perform a TPMS Tire Position Learn / Relearn using the inexpensive EL-50448 GM TPMS Relearn Tool.

I demonstrate the procedure on a 2015 Buick Encore (Leather trim). Other trim levels may have a slightly different gauge cluster, but the process is nearly the same across many GM (Buick, Cadillac, Chevrolet, GMC, Hummer & Pontiac) vehicles.

On some older GM vehicles, you can perform the tire position relearn with the air out/in method. I’ve attempted this method using replacement sensors and was unsuccessful. Only when I used the EL-50448 would the car accept the new sensors.

This relearn is required after:
✅ Rotating tires
✅ Replacing or installing new TPMS sensors
✅ Installing new wheels or tires
✅ Repairing/replacing a flat tire
