This Smart Sensor kit replaces the tire pressure sensors on the first generation Buick Envision sold in the US. The sensors are pre-programmed for the Envision's 315 MHz GM system, so they can be mounted and learned to the vehicle without a programming step.
The Envision arrived in the US for the 2016 model year, so the oldest ones are now at the age where the sealed batteries in the factory sensors start to give out. When that happens the TPMS light stays on or the pressure display shows dashes for one or more tires. These Smart One sensors install in the factory location and report pressures to the Envision's driver information center the same way the originals do.
They are tested to SAE J1205 and J1206 standards for heat, cold and corrosion, and the tire must be dismounted to install them.
Relearn on the Envision
The Envision uses GM's standard relearn. Start the tire learn mode from the driver information center, or hold the lock and unlock buttons on the key fob until the horn chirps twice. Then wake each sensor with a TPMS tool in order: left front, right front, right rear, left rear, with a horn chirp after each one. A scan tool can also run the relearn.
Common questions
Does this fit a 2021 or newer Envision? No. The redesigned 2021 Envision uses a 433 MHz sensor. This kit is for the first generation.
The listing says 2015. Does that matter? The 2015 Envision was sold in China only. For US vehicles, this kit covers 2016 through 2020.
Can a tire shop do the relearn? Yes. Any shop with a TPMS tool can complete it in a few minutes.
