Understanding EADO ET TPMS Compatibility
The Changan EADO ET (often sold under the Oshan or Kaicene badges in certain markets) uses a 433MHz TPMS system that is shared across several Changan Group platforms. If you own an EADO ET from the 2015–2024 generation, the factory sensors were typically black, clamp-in units with a metal valve stem and a 433MHz transmitting frequency. The BH-Sens BL-ST-042 is an exact OE replacement, meaning it matches the physical dimensions, thread size, and signal protocol used by your car’s TPMS receiver module.
Key Technical Specs of the BL-ST-042
| Parameter | Value |
|---|---|
| Brand | BH-Sens (Baolong Technology) |
| Frequency | 433 MHz |
| OE Numbers | 3601010BK01, 3601010MK01, 3601010MK51 |
| Type | Clamp-in, pre-programmed |
| Valve Stem Material | Metal (aluminum or steel depending on batch) |
| Torque Specification | Tighten to 4.0–4.5 Nm (check your manual) |
| Battery Life | 5–7 years under normal driving conditions |
The sensor is sold as a direct “plug and play” replacement for any EADO ET that came factory-equipped with one of the three OE numbers listed above. No cloning or relearn tool is strictly necessary on most Changan EADO ET models if the car is fitted with the correct 433MHz receiver – the sensor self-programs after a short drive.

Year Coverage for the EADO ET (EADO ET)
Changan introduced the EADO ET (electric version) around 2015, and continued production through the 2024 model year with minimal changes to the TPMS system. The following table summarizes known fitment:
| Changan EADO ET Model Year | Compatible OE Numbers | Notes |
|---|---|---|
| 2015–2017 | 3601010BK01, 3601010MK01 | Early models use the BK01 variant |
| 2018–2020 | 3601010MK01, 3601010MK51 | Mid-cycle update; both part numbers interchangeable |
| 2021–2024 | 3601010MK51 | Latest revision, backward compatible with earlier years |
Important: If your EADO ET was manufactured before 2015 (unlikely for the ET nameplate) or has been retrofitted with a different TPMS system, verify the existing sensor part number first. The BL-ST-042 will not work with 315MHz systems or aftermarket universal sensors that require programming via a tool.
How to Confirm Your EADO ET Uses 433MHz
- Check the existing sensor. Look for a number stamped on the sensor body – if it reads 3601010BK01, 3601010MK01, or 3601010MK51, you have the correct frequency.
- Use a scanner. Many OBD-II TPMS tools will show the sensor frequency. If it says 433MHz, the BL-ST-042 will work.
- Look at the valve stem. Factory 433MHz sensors on the EADO ET have a metal valve stem, not rubber. Rubber stems usually indicate a different system.
- Consult your owner’s manual. The TPMS section often lists the frequency and recommended sensor part numbers.

How to Verify Fitment Before Buying
Buying an aftermarket TPMS sensor online is straightforward once you know what to check. Follow these steps to avoid returns or incompatibility.
Step 1: Gather Your Vehicle Info
You need one of the following:
- Your vehicle’s VIN (17-character code found on the dashboard or driver’s door sticker).
- The OE part number of one of your current TPMS sensors (remove the wheel and read the number on the sensor).
- Your model year and sub-model (e.g., EADO ET 2021 Luxury, or EADO ET 2023 Pro).
Step 2: Cross-Reference with the BL-ST-042
If your existing sensor shows one of the three OE numbers above, the BL-ST-042 will fit physically and electrically. If you only have the VIN, many online parts catalogs (including our database at RisenAuto) can tell you the original TPMS part number. The BL-ST-042 is designed to match all three OE numbers, so it covers almost every EADO ET from 2015–2024.
Step 3: Check the Relearn Procedure
Most EADO ET models require a simple auto-relearn after a sensor replacement. The car automatically detects the new sensor’s ID after driving above 25 mph for about 10 minutes. No special tool is needed. However, some dealerships or aftermarket shops may prefer to use a TPMS tool to speed up the process. The BL-ST-042 is pre-programmed, so it transmits a static ID that the car’s receiver already accepts – you do not need to clone the old sensor ID.
Step 4: Verify Physical Fit
The BL-ST-042 is a clamp-in sensor with a standard 0.453-inch valve stem thread (common on most passenger cars). The EADO ET uses this same thread pattern. Remove your old sensor, install the new one using a torque wrench set to the manufacturer’s specification (usually 4.0–4.5 Nm), and mount the tire. Over-torquing can damage the sensor housing.

What If My EADO ET Uses a Different Frequency?
A small number of EADO ET models exported to certain regions (e.g., some Middle Eastern markets) may use a 315MHz system. The BL-ST-042 is strictly 433MHz, so it will not work on those vehicles. If you suspect your car is 315MHz:
- Check the sensor label for a number like 3601010XX01 – the last two digits differ.
- Use a frequency tester or ask your local dealer.
- For 315MHz, we carry other BH-Sens models (contact us for the correct SKU).

Recommended Part
For a hassle-free replacement on your Changan EADO ET (2015–2024), the BL-ST-042 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Changan, Kaicene, Oshan | OE# 3601010BK01, 3601010MK01, 3601010MK51 (SKU: BL-ST-042) is the correct choice. It ships pre-programmed, requires no additional setup, and comes with a metal valve stem to match the factory look.
Tip: Always replace all four sensors at once if their battery life is unknown. Mixing old and new sensors can cause inconsistent readings because old batteries weaken faster.

FAQ
How do I know if my EADO ET TPMS sensor is 433MHz or 315MHz?
Look at the printed number on the existing sensor. If it contains 3601010BK01, 3601010MK01, or 3601010MK51, it is 433MHz. Alternatively, use a TPMS diagnostic tool that reads frequency – most affordable scanners will display 433 or 315. Also, if your car was built after 2015 and was sold in China or Europe, it is almost certainly 433MHz.
Will the BL-ST-042 work without a TPMS programming tool?
Yes. The sensor comes pre-programmed with a compatible ID that Changan’s receiver recognizes. After installation, drive the car above 25 mph for a few minutes – the system will automatically relearn and clear the warning light. No tool is required for the EADO ET.
Can I use this sensor on a Changan other than the EADO ET?
Yes. The BL-ST-042 is listed as compatible with Changan, Kaicene, and Oshan models that use the same OE numbers. Common examples include the Changan CS35, CS75, and Oshan X7, but always verify using the sensor’s OE number or your VIN.
What torque should I use when installing the BL-ST-042?
The sensor manufacturer recommends 4.0–4.5 Nm (or about 35–40 inch-pounds) for the clamp nut. Over-tightening can crack the sensor body or strip the valve stem. If you don’t have a torque wrench, tighten the nut snugly with your fingers and then give it a ¼ turn with a standard wrench – but a torque wrench is always safer.
