Tesla TPMS Guide: Bluetooth vs 433MHz Sensor Fitment by Model and Year

Two TPMS generations are now in service, and they are not interchangeable

SHENZHEN, 3 November 2026 — Shenzhen June Electronics has published a fitment guide for Tesla tire pressure sensors, addressing a problem that has become routine in workshops: identifying whether a given vehicle uses the newer 2.4GHz Bluetooth (BLE) system or the earlier 433MHz radio system before a replacement sensor is ordered.

Tesla did not change protocols across the range at once. The transition rolled out model by model over roughly twelve months, which means two vehicles registered in the same year can require different sensors. Because both types are compact black sensors on a metal valve stem, the difference is rarely visible once a wheel is assembled.

The boundary is a build date rather than a model year, a distinction that accounts for a large share of incorrect orders. A car sold as a 2021 model may have been built before the switch.

Three checks that resolve the question

• Part number on the old sensor. The current Bluetooth family carries numbers including 1490701-01-B, 1490701-01-C, 1490750-01-A and 1490750-00-A. A different sequence indicates the earlier 433MHz generation.
• Dual-protocol tool scan. A tool that supports both systems will identify the generation within seconds. A tool restricted to 315/433MHz stays silent on a Bluetooth car — silence is a result, not a fault.
• VIN confirmation through Tesla service. The definitive answer when the sensor marking is unreadable, and the cleanest protection for a distributor record.

Why the two cannot be interchanged

The separation is physical, not a firmware setting. A 433MHz sensor broadcasts on a fixed UHF frequency; a Bluetooth sensor runs a 2.4GHz Low Energy stack that pairs with the vehicle. No programming tool converts one into the other, and no relearning procedure will bring a 433MHz sensor onto a Bluetooth car. The typical symptom of a mismatch is a single wheel showing a blank value while the other three report correctly.

Advice for workshops and distributors

With both generations present in most markets, the practical response is to stock both and label bins by build date rather than model year. The company recommends testing one sensor from each batch on a known Bluetooth car and a known 433MHz car before shipping, recording the VIN or original part number on every Tesla order, and keeping the two generations in separate bins.
