Why Fitment Verification Matters for 菱智PLUS
The 菱智PLUS is a popular MPV in the Chinese domestic and export markets, often used for fleet, taxi, or family transport. TPMS sensor replacement is common due to battery life (typically 5–7 years) or physical damage during tire changes. Ordering the wrong sensor means wasted time, return shipping, and a vehicle without functioning TPMS—a safety issue you don’t want.
The BL-ST-052 sensor is pre-programmed and clamp-in, which simplifies installation, but you still need to confirm three things: vehicle year range, OE part number match, and TPMS frequency. Below, we break down exactly how to do that.
Compatible 菱智PLUS Model Years
Based on OE data and aftermarket cross-references, the BL-ST-052 fits 菱智PLUS models produced from approximately 2016 to 2024. This covers the first generation (M5/M5L) and the current facelift versions. However, there are exceptions:
- 2016–2018 models – Almost always 433MHz. Direct fit.
- 2019–2021 models – Mostly 433MHz, but some late 2021 units switched to 315MHz in certain export markets. Verify.
- 2022–2024 models – Majority remain 433MHz, but check the sensor part number on your old sensor.
If your 菱智PLUS was manufactured before 2016, the TPMS system may be different—contact us with your VIN to confirm.
How to Verify Fitment Step by Step
Step 1: Locate Your OE Part Number
Your existing TPMS sensor has a part number stamped on the metal body. The three OE numbers for this sensor are:
- CM5B3685020
- CM5B3685020S
- SX5G3685020B
Where to find it: Remove the tire, or look through the valve stem area if the sensor is visible. In many 菱智PLUS models, the sensor is mounted inside the wheel on the valve stem. You may need a tire shop to access it.
Step 2: Check the Frequency
Use a TPMS diagnostic tool (such as an Autel or ATEQ) to read the sensor frequency. Most 菱智PLUS use 433MHz, but some export models may use 315MHz. If you don’t have a tool, check your owner’s manual or call a dealer.
Step 3: Confirm the Sensor Type
The BL-ST-052 is a clamp-in sensor. 菱智PLUS uses clamp-in sensors from the factory. If your vehicle has snap-in sensors (rare for this model), this sensor won’t fit.
Fitment Reference Table
| Vehicle Model | Year Range | OE Part Numbers | Frequency | Sensor Type | BL-ST-052 Compatible? |
|---|---|---|---|---|---|
| 菱智PLUS M5 | 2016–2020 | CM5B3685020, CM5B3685020S | 433MHz | Clamp-in | Yes |
| 菱智PLUS M5L | 2018–2023 | CM5B3685020S, SX5G3685020B | 433MHz | Clamp-in | Yes |
| 菱智PLUS (export) | 2019–2024 | SX5G3685020B | 433MHz (verify) | Clamp-in | Yes (if 433MHz) |
| 菱智PLUS (late 2021) | 2021 | CM5B3685020S | 315MHz (some) | Clamp-in | No (315MHz) |
Note: This table is based on common fitments. Always verify with your VIN or old sensor part number.
Common Compatibility Pitfalls
- Mixing frequencies: If your 菱智PLUS uses 433MHz sensors, installing a 315MHz sensor will not communicate with the TPMS module. The dash light will stay on.
- Used sensors: Do not install used sensors—battery life is limited. The BL-ST-052 is new and pre-programmed, so it’s ready to install.
- Programming required? No. This sensor is pre-programmed to OE specifications. It will auto-learn with most 菱智PLUS TPMS modules. In rare cases, you may need a relearn procedure (see your manual).
Recommended Part
For direct replacement on your 菱智PLUS, we recommend the BL-ST-052 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Forthing | OE# CM5B3685020, CM5B3685020S, SX5G3685020B. It matches the OE fit exactly for models using CM5B3685020, CM5B3685020S, or SX5G3685020B. It’s a clamp-in, 433MHz sensor that installs like the original.
FAQ
How do I know if my 菱智PLUS uses 433MHz or 315MHz TPMS?
Check the old sensor’s part number. If it matches CM5B3685020, CM5B3685020S, or SX5G3685020B, it’s 433MHz. If the part number is different (e.g., CM5B3685020A or a number ending in “315”), it may be 315MHz. A TPMS diagnostic tool will give you the exact frequency.
Can I install the BL-ST-052 myself?
Yes, if you have a tire machine and can remove the tire bead. The sensor is clamp-in, so you simply remove the old valve nut, place the new sensor, and torque the nut to 4.0–4.5 Nm (check your vehicle manual for exact spec). After installation, drive the vehicle at 20+ mph for 10 minutes to trigger auto-learn.
What if my 菱智PLUS is a 2022 model with a different OE number?
Contact us with your VIN. Some very late models may use a revised sensor. We can cross-reference the OE number or recommend the correct BL-ST-052 variant. Do not assume compatibility without checking.
Will this sensor work on other Forthing models besides 菱智PLUS?
Yes. The BL-ST-052 also fits Forthing T5, SX5, and some Joyear models with the same OE numbers. Always verify the OE number and frequency before purchase.
