315MHz vs 433MHz TPMS Sensors

November 28, 20244 min read

A practical comparison of the two common TPMS frequency bands and why dual-frequency coverage matters.

Frequency choice is not interchangeable. A wrong TPMS frequency creates service delays and unnecessary diagnostic work.

Why two frequencies exist

Different vehicle markets adopted different RF standards. North American applications commonly use 315MHz, while many other markets use 433MHz.

What goes wrong in service

If the frequency is wrong, the vehicle will not communicate with the sensor even if the fitment and valve style look correct.

  • +Confirm market and model-year coverage.
  • +Use a programming tool that verifies sensor output.
  • +Avoid mixing assumptions across imported vehicles.

Why dual frequency helps

Dual-frequency programmable sensors reduce SKU count and simplify stocking for mixed fleets, especially in export markets.
