2020-2020 Cadillac CT4 Pre-Programmed Smart TPMS Tire Pressure Sensors Kit

This Smart Sensor kit replaces the tire pressure monitoring system sensors on a 2020 Cadillac CT4, including the CT4-V. The sensors arrive already programmed with the CT4's 433 MHz GM protocol, so they can go straight into the wheels with no programming tool and no trip to the dealer.

Most CT4 owners shop for TPMS sensors for one of three reasons: the low tire pressure light stays on even with the tires aired up, a sensor was damaged during a tire change, or they are setting up a second set of wheels for winter tires. The factory sensors run on a sealed battery, and when it gives out the whole sensor has to be replaced. These Smart One sensors are a direct replacement for the original parts and report pressure to the CT4's instrument cluster the same way the factory sensors do.

Each sensor mounts inside the wheel in the factory location, so the tire has to come off the rim to install them. Any tire shop can do it during a mount and balance. The sensors are built to SAE J1205 and J1206 test standards for heat, cold and corrosion.

Getting the car to recognize the new sensors

Once the new sensors are in, the CT4 has to learn their IDs. On the 2020 CT4 this is not automatic: the relearn is started from the instrument cluster menu, then each sensor is woken with a TPMS tool in order, left front, right front, right rear, left rear, with a horn chirp after each one. Any tire shop with a TPMS tool can do it in a few minutes, and a scan tool can also run the relearn.

Why buy pre-programmed

Universal programmable sensors are cheap, but they need a programming tool and the right software to set them up for your car. These come ready to install, which saves a step at the tire shop. Orders placed before 10am Eastern on a business day ship the same day.

Common questions

Will these work on a CT4-V? Yes. The 2020 CT4-V uses the same TPMS system as the standard CT4.

Do I need a programming tool? No. The sensors are programmed before they ship. The car still has to learn the new sensor IDs, which takes a TPMS tool and a few minutes at any tire shop.
