TPMS OE Number Data Governance
This article explains how XSD Precision governs TPMS OE numbers and vehicle application records through a five-level vehicle database structure, versioned updates, evidence states and a closed RFQ, testing and after-sales workflow.
Core assessment
In the TPMS sensor business, database size is often reduced to two numbers: how many OE numbers are listed and how many vehicle applications are included. For tire shops, importers, distributors and OEM/ODM customers, the more important question is whether a supplier can identify the right application when given an OE number, vehicle information or a photo of the original sensor, and explain the evidence, version and verification status behind that match.
We therefore manage 2,000+ OE numbers and 10,000+ vehicle application records as a governed product-data system rather than a static marketing catalogue. The database supports three related but distinct workflows: OE replacement sensors, programmable TPMS sensors and professional service operations.
Application data model
For an OE replacement route, the buyer normally knows the original part number or can provide a photo of the original sensor. We check the OE number, vehicle make, model, year, sales market, frequency, valve type and wheel requirements.
For a programmable sensor route, a vehicle appearing in a list is not by itself a complete support claim. We also need to confirm the target market, 315 or 433 MHz requirement, valve configuration, programming tool, software or database version and, where required, a real test vehicle.
This distinction prevents a common mistake: treating the number of OE cross-references as identical to programmable vehicle coverage. The two data sets can be related, but they cannot be treated as the same thing.
Normalization checks
Our basic data unit is not an isolated OE number. It is an application record with context, including:
- OE number, replacement number and internal sensor reference;
- vehicle make, model, year and sales market;
- 315 MHz or 433 MHz information;
- rubber or metal valve requirements;
- application route: OE replacement or programmable;
- required programming tool and relearn method;
- source, collection date and current version;
- status such as verified, pending verification, partially verified or restricted;
- test records, photographs, reports and exception notes.
This gives sales teams more than a similar-looking number. Engineering teams can trace why a relationship exists, where it applies and what evidence is still missing.
Evidence states
The same vehicle name can have different sensor protocols, frequencies, valve structures or relearn procedures across years, markets and configurations. Vehicle data must therefore be separated by these dimensions instead of being compressed into one broad row.
During intake and review, we check whether the vehicle identity is complete, whether markets have been incorrectly combined, whether frequency information is consistent, whether OE formatting and replacement relationships are preserved, whether the programming method has evidence, and whether valve or wheel requirements need separate notes.
Hierarchical vehicle-database management
Here, “hierarchical management” primarily refers to the structure of the vehicle database, rather than assigning a simple confidence score to each record. Each vehicle application is connected through several levels so that different years, markets and configurations are not incorrectly merged.
Level 1: Make and vehicle family
This level records the vehicle make, manufacturer and broad vehicle family. It provides the brand index, search entry and regional coverage view.
Level 2: Series, model and body version
The database then separates the specific series, model, body style and powertrain version. Models with similar names but different platforms, wheels or TPMS configurations must not be merged only because the make or series is the same.
Level 3: Model year, market and configuration
Each model is separated by model year, North American or other sales market, configuration and production stage. Frequency, sensor protocol, valve type and relearn method often change at this level.
Level 4: TPMS application relationship
At the specific year and market level, the database links frequency, sensor route, programming tool, relearn method, rubber or metal valve requirement, test evidence and exception records.
Level 5: OE and sensor mapping
Finally, OE numbers, replacement numbers, XSD sensor models, programmable-sensor solutions and packaging SKUs are linked to the specific application. One OE number may relate to multiple vehicle applications, and one programmable sensor may cover multiple applications, but each relationship must retain its conditions rather than becoming an unconditional one-to-one replacement claim.
This structure allows maintainers to move from make to a specific application and also trace an OE number back to its make, series, model year and market. Review states such as draft, pending review, approved, downgraded, suspended and closed remain separate governance fields; they do not replace the vehicle database hierarchy.
Versioned updates
TPMS data is not a file that can be imported once and left unchanged. New vehicle applications, market differences, tool updates, sensor batches and field feedback may all affect a record.
Important changes therefore retain a version, source, changed fields and reviewer. The normal update cycle is:
1. Collect OE data, vehicle information or test feedback.
2. Normalize fields and check duplicates.
3. Check conflicts against existing vehicle, frequency and sensor relationships.
4. Mark records as added, changed, downgraded or closed.
5. Obtain product, engineering or quality review.
6. Update the customer-facing guide and internal RFQ data.
7. Keep the previous version so historical quotations and test results remain explainable.
RFQ, testing and after-sales workflow
The value of the database is not simply that it can be searched. It should help a customer complete a traceable project.
When a customer submits an OE number, original-sensor photo, vehicle information or target vehicle list, the workflow should identify missing frequency, valve, quantity, packaging or tool information before a quotation is treated as complete.
When a sample test is approved, the record should include the real vehicle, tool, installation steps, photos, feedback deadline and result. A sample is a qualification tool, not an unconditional free gift, and a test result may be positive, negative or inconclusive.
When a field issue occurs, the after-sales record should link back to the vehicle, sensor, tool and operating procedure. An exception then becomes input for the next data and guide revision rather than an isolated closed ticket.
Buyer inputs
For tire shops and installers, structured data can reduce search time, mismatches and rework.
For importers and distributors, it helps compare SKU coverage, 315/433 MHz mix, inventory complexity, packaging and regional demand.
For OEM/ODM customers, it connects target vehicles, sensor route, samples, pilot quantities, MOQ and production timing in one project review.
The database should not be understood as an unconditional vehicle guarantee. A reliable RFQ still requires the vehicle, year, market, OE number or original-sensor photo and, when needed, confirmation on the real vehicle with the specified tool.
Engineering conclusion
2,000+ OE numbers and 10,000+ vehicle application records become useful business capability only when they are supported by standard fields, version control, evidence levels, engineering review and field feedback.
Our goal is not a database that merely looks large. It is a system that can answer four questions for every record: What does it apply to? What is the evidence? What is verified today? What is the next action if there is an exception?
That is the foundation of XSD Precision’s TPMS data management approach: define the application first, verify the evidence, state the boundary clearly and let every test and RFQ improve the next match.
Engineering conclusion
Before public release, the current deduplicated counts and the definition of an OE number and vehicle application should be confirmed by the data owner. The article does not promise a fixed coverage percentage, tool model, MOQ, lead time, price, certification or universal vehicle compatibility.
