Frequently Asked Questions

Where is the TPMS receiver module?

The TPMS receiver is typically located inside the vehicle, often behind a trim panel in the wheel well area, under the dash, or in the trunk. Some vehicles integrate it into the BCM.

Can all four sensor failures mean a module problem?

Yes. If all four sensors stop communicating simultaneously, the TPMS receiver module is the most likely cause rather than all four sensors failing at the same time.

Does the TPMS module need programming?

Yes. A replacement TPMS module must be programmed with the sensor IDs and vehicle-specific parameters. This typically requires a dealer-level scan tool.
