Why Fitment Verification Matters for the QIN L DM-i
The QIN L DM-i is a popular plug-in hybrid from BYD, and like many modern Chinese-market vehicles, it uses a proprietary TPMS system. Swapping a faulty or dead sensor with a pre-programmed unit like the BL-ST-062 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits BYD, Denza, Fangchengbao, Toyota, Young | OE# 4260703011, SA3HE3609200B, SFH3609200B can save you a trip to the dealer — but only if the sensor matches your car’s exact specification. A mismatched sensor may not communicate with the receiver module, leaving the TPMS light permanently on or causing false alerts.
Which Vehicles Does the BL-ST-062 Cover?
This sensor is built by BH-Sens (Baolong Technology), one of the largest OEM TPMS suppliers for Chinese automakers. It is pre-programmed with the necessary ID and protocol to work as a direct replacement for several BYD, Denza, Fangchengbao, and Toyota models.
Compatible Brands and Models (Partial List)
| Brand | Compatible Models | Approximate Model Years |
|---|---|---|
| BYD | QIN L DM-I (includes QIN L DM-i, QIN Plus DM-i, QIN EV), Han, Tang, Song, Yuan | 2020–2025 (check your specific year) |
| Denza | D9, X, N7 | 2021–2025 |
| Fangchengbao | Bao 5, Bao 3 | 2023–2025 |
| Toyota | bZ4X, some Corolla & Camry hybrids (with 433MHz system) | 2021–2024 |
Important: This is not a universal sensor. It is specifically designed for 433MHz systems. If your QIN L DM-i was built before 2020, or if you’ve retrofitted aftermarket wheels with different sensors, you must verify first.
How to Verify Fitment Before Buying (Step‑by‑Step)
1. Locate the OE Number on Your Current Sensor
Remove the wheel and look for a six‑digit or alphanumeric code stamped on the sensor housing. The BL-ST‑062 replaces the following OE numbers:
- 4260703011
- SA3HE3609200B
- SFH3609200B
- SGH3609200B
- SGHA3609200B
If your sensor has any of these numbers (or a cross-reference), the BL-ST-062 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits BYD, Denza, Fangchengbao, Toyota, Young | OE# 4260703011, SA3HE3609200B, SFH3609200B will be a direct clamp‑in fit.
2. Confirm the Frequency
Nearly all modern BYD vehicles use 433MHz, but check the label on your current sensor or your owner’s manual. The BL-ST‑062 is 433MHz only — do not use it in a 315MHz system.
3. Check the Sensor Type and Valve Stem
This sensor is clamp‑in (metal valve stem, nut‑retained). If your original sensor is snap‑in (rubber stem, no nut), this won’t fit without an adapter. The QIN L DM-i uses clamp‑in from the factory, so you should be fine.
4. Verify Vehicle Year Range
While the BL-ST‑062 fits many 2020‑2025 BYD models, there have been mid‑cycle protocol updates. For instance, some early 2020 QIN models used a different ID format. A good rule: if your QIN L DM-i was manufactured after January 2021, it’s almost certainly compatible. For 2020 models, check the sensor OE number first.
5. Use a TPMS Programming Tool (Optional but Recommended)
Even though this sensor comes pre‑programmed, some vehicle modules require a one‑time “learn” procedure. A simple 433MHz TPMS trigger tool (available for under $20) can confirm the sensor transmits correctly before you mount the tire.
When Should You Replace All Four Sensors?
If only one sensor on your QIN L DM-i has failed, you can replace just that one — the BL-ST‑062 will match the existing sensor IDs. However, if your car is more than 5 years old or you’ve had multiple sensor failures, replacing all four at once is more cost‑effective. The BL-ST‑062 is sold individually, so you can buy a set of four for a complete refresh.
Installation Tips for the QIN L DM-i
- Torque the valve stem nut to your vehicle’s specification (typically 3–4 Nm). Over‑tightening can crack the sensor housing.
- Use a fresh rubber grommet and metal washer if reusing the old valve stem.
- After mounting, drive the car at 20–30 mph for 10 minutes to let the on‑board receiver learn the new sensor ID.
- If the TPMS light stays on, consult the service manual for the relearn procedure (some models require a magnet tool or diagnostic tool).
Recommended Part
For a direct drop‑in replacement on your QIN L DM-i (and many other BYD vehicles), the BL-ST-062 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits BYD, Denza, Fangchengbao, Toyota, Young | OE# 4260703011, SA3HE3609200B, SFH3609200B offers reliable performance at a fraction of dealer cost. It matches the OE frequency and uses the same clamp‑in design as the factory sensor. Always verify your OE number before purchasing.
FAQ
Does the BL-ST‑062 fit the BYD QIN L DM-i 2024 model?
Yes, the 2024 QIN L DM-i uses the 433MHz system compatible with OE numbers SA3HE3609200B and SFH3609200B, which the BL-ST‑062 replaces. Check the label on your original sensor to be certain.
Can I install this sensor myself, or do I need a shop?
If you have basic tools (jack, tire lever, torque wrench) and experience mounting tires, you can install it yourself. Keep in mind that after installation, the sensor may need to be “learned” by the vehicle’s TPMS module. Some owners can drive a short distance to auto-learn; others may need a diagnostic tool. A professional installation is recommended if you’re not comfortable with tire work.
Will this sensor work on a Toyota bZ4X that uses 433MHz?
Yes, the BL-ST‑062 is listed for certain Toyota 433MHz systems. However, confirm your bZ4X’s OE sensor number. Toyota often uses different ID formats even at the same frequency, so cross-reference with the OE numbers listed above.
What if my QIN L DM-i has a different OE number not listed here?
If your sensor’s OE number does not match any of the five listed, the BL-ST‑062 may still be compatible as many BYD sensors are rebranded Baolong units. Contact the seller with your OE number to verify. Avoid guessing — a mismatched sensor will not fix your TPMS light.
