Why Fitment Matters for Your GRENADIER
Grenadier vehicles use a direct TPMS system where each wheel-mounted sensor transmits pressure and temperature data to the vehicle’s ECU. Installing an incompatible sensor—wrong frequency, incorrect protocol, or mismatched OE number—will trigger a warning light and may prevent the system from learning the new sensor ID.
The BL-ST-066 is a clamp-in 433MHz sensor manufactured by BH-Sens (Baolong Technology). It replaces several OEM part numbers used across the Grenadier lineup, but not all Grenadier models use the same sensor hardware.
Compatible Models and Year Coverage
Based on OE number cross-referencing, the BL-ST-066 fits Grenadier models built after 2022 that use the 433MHz frequency. Earlier 2021–2022 models may use 315MHz sensors—verify before purchase. The table below shows confirmed fitment for common Grenadier variants:
| Grenadier Model | Approx. Year Range | Compatible OE Numbers | Notes |
|---|---|---|---|
| Utility Wagon | 2023–2025 | 3641050RD01, 407002GL0A, 407002GN0A, 407002GX0A | Most common fit |
| Station Wagon | 2023–2025 | 407002JD0A, 407003VU0A, 407004CB0A | Check for 433MHz sticker |
| Trialmaster | 2023–2025 | 407004CB0B, 407005663R, 407006UA0A | Confirm valve stem length |
| Fieldmaster | 2023–2025 | 407002GL0A, 407002GN0A | Identical to Utility Wagon |
Important: Not all Grenadier models are covered. If your vehicle uses OE number 40700xxxxx starting with “40700” but not listed above, it may require a different sensor.
How to Verify Fitment Before Buying
Follow these steps to avoid returning parts:
- Check your current sensor’s frequency – Look for a label on the sensor body (usually visible through the wheel well or after tire removal). It should read “433MHz” or “315MHz.” The BL-ST-066 only works with 433MHz systems.
- Locate the OE part number – This is printed on the sensor housing. Common Grenadier OE numbers are listed above. If yours matches any of the 9 numbers in the product description, the sensor is compatible.
- Use a TPMS diagnostic tool – Handheld tools like the Autel TS508 or Bartec TPMS tool can read your vehicle’s sensor IDs and confirm whether the BL-ST-066 will work. Many tire shops offer this check for free.
- Check your vehicle’s build date – Grenadier models built after June 2022 almost always use 433MHz. Earlier builds may vary. Open the driver’s door and check the placard for the month/year of manufacture.

FAQ
Does the BL-ST-066 work on all Grenadier models?
No. It fits only models using 433MHz sensors and the listed OE numbers. Grenadier models with 315MHz sensors or non-listed OE numbers require a different sensor (check our store for the BL-ST-067 if you have 315MHz).
Do I need to program the sensor after installation?
Yes. After installing the BL-ST-066, the sensor ID must be learned by your Grenadier’s TPMS system. This can be done with a TPMS tool or by a shop. Some Grenadier models also support auto-relearn after driving above 20 mph for 10 minutes.
Can I fit the BL-ST-066 on a 2021 Grenadier?
Possibly, but only if your 2021 model uses 433MHz sensors. Most 2021 Grenadiers shipped with 315MHz sensors. Check the sensor label before ordering—if it reads “315MHz,” this part will not work.
What is the difference between the BL-ST-066 and a Genuine Grenadier TPMS sensor?
The BL-ST-066 is an aftermarket alternative manufactured by BH-Sens (a Tier 1 OE supplier for many brands). It uses the same technology and protocol as the genuine part but costs significantly less. Performance and durability are equivalent when properly installed.
