The TPMS Sensor (Part No. 1100-20032) you asked about is a dual-frequency (2-in-1) TPMS sensor that supports both 315 MHz and 433 MHz radio frequencies — meaning it can communicate on either band depending on the vehicle’s TPMS system.
📡 What “2-in-1” Means
A 2-in-1 TPMS sensor is designed to be compatible with multiple vehicle makes/models that use different TPMS broadcast frequencies:
-
315 MHz — used on many North American vehicles
-
433 MHz — used on many European/Asian vehicles
By supporting both frequencies, this sensor can be programmed (or auto-configured) to work with either standard, so it’s more versatile than a single-frequency sensor.
📊 How It Works
-
When the sensor is activated (by vehicle scan tool or driving above a certain speed), it will transmit tire pressure and temperature data at the frequency expected by the vehicle’s TPMS module.
-
TPMS systems in the vehicle will listen on the correct frequency (315 MHz or 433 MHz), and the sensor will broadcast on that channel.
🧠 Why Dual-Frequency Is Useful
-
You can stock a single part number instead of two different sensors
-
Supports vehicles from multiple regions
-
Great for fleets, shops, and universal applications
