TPMS Frequency and Protocol Matching Guide
A buyer-focused guide to matching TPMS sensors by 315MHz or 433MHz frequency, vehicle protocol, OE number, relearn workflow and validation evidence before RFQ.
Quick assessment
Many TPMS sourcing mistakes start when buyers match only the visible frequency label. A correct replacement also needs protocol, OE reference, vehicle market, relearn logic and validation evidence.
Use this guide before requesting OE replacement sensors, programmable TPMS alternatives, sample testing, database support or a shop-service workflow.
Decision factors
- 315MHz and 433MHz are market signals, not complete compatibility proof.
- The same OE family can have different protocol, stem, region or relearn requirements.
- Programmable sensors still need tool compatibility, database coverage and write verification.
- Vehicle year, trim and destination market can change TPMS requirements.
- Sample approval should include RF communication, pressure reading, wake-up and relearn behavior.
Matching decision matrix
| Review area | Recommended action | Validation evidence |
|---|---|---|
| Frequency | Confirm 315MHz or 433MHz against vehicle market and OE record. | OE reference, original sensor label, scanner reading or service database screenshot. |
| Protocol | Verify the sensor communication protocol and supported vehicle platform. | Programming tool compatibility result and read-back data. |
| OE number | Cross-check OE number, supersession and equivalent sensor family. | OE list, vehicle VIN/year/market and approved replacement route. |
| Relearn workflow | Confirm whether the vehicle uses auto relearn, OBD relearn or manual procedure. | Workshop test record, tool screenshot and post-install dashboard result. |
| Sample validation | Run a controlled sample test before channel or batch approval. | Pressure reading, RF response, leak test, relearn result and failure notes. |
Verification workflow
- Collect the OE number, original sensor photo, vehicle year, trim, destination market and wheel/valve requirement.
- Read the original sensor where possible to confirm frequency, ID behavior and protocol clues.
- Program the proposed sensor and read back ID, frequency and vehicle application data.
- Install or simulate the sensor, then confirm wake-up, pressure reading and RF communication.
- Complete the required relearn workflow and record the final dashboard or scan-tool result.
- Keep batch, firmware, tool version and test notes for later warranty or channel support.
Common sourcing risks
If buyers confirm only frequency, they can still receive sensors that transmit on the right band but fail to relearn, show unstable readings, require the wrong tool route or create repeated support tickets. A clean match uses frequency, protocol, OE evidence and real workflow validation together.
Information needed before RFQ
- OE number or original sensor photo.
- Vehicle make, model, year, trim and target market.
- Required frequency and known tool ecosystem.
- Valve stem type, service kit and wheel context.
- Expected quantity, sample plan and validation standard.
Engineering conclusion
TPMS frequency is the starting point, not the approval point. For sourcing, the stronger route is frequency plus protocol plus OE evidence plus relearn validation.
