Why Fitment Verification Matters for Eπ TPMS Sensors
Eπ is a growing Chinese EV brand under the Dongfeng Motor Group, known for models like the Eπ 007 and Eπ 008. While the BL-ST-039 sensor covers many Eπ vehicles, not every Eπ uses the same sensor design. Using an incorrect sensor can cause constant TPMS warning lights, inaccurate pressure readings, or no signal at all. You want a sensor that matches both the physical mounting and the communication protocol of your vehicle’s TPMS module.
Which Eπ Models Use the BL-ST-039 Sensor?
Based on current aftermarket data, the BL-ST-039 fits:
- Eπ 007 (2023–present)
- Eπ 008 (2024–present)
- Some earlier Eπ crossover prototypes (check your VIN)
The sensor is also compatible with other Dongfeng-affiliated brands including Aeolus, Mhero, Nammi, and Voyah, which share similar TPMS architectures.
Compatible Model & Year Table
| Brand | Model | Year Range | OE Numbers | Notes |
|---|---|---|---|---|
| Eπ | 007 | 2023–2025 | E300019160, E300020260 | Confirm trim: base, Pro, or AWD |
| Eπ | 008 | 2024–2025 | H56A7920001AC | Some early production used different sensor |
| Aeolus | Yixuan, Haohan | 2021–2025 | E300019160 | Check for 433MHz system |
| Mhero | 917 | 2023–2025 | E300020260 | Limited production model |
| Voyah | Free, Dream | 2022–2025 | H56A7920001AC | Only clamp-in type sensors |
Important: Year ranges are approximate. Always verify using your vehicle’s VIN or existing sensor OE number.
How to Verify Fitment Before You Buy
Step 1: Locate the OE Number on Your Current Sensor
Remove one wheel and look at the metal sensor body. The OE number is laser-etched or printed on the side. Common OE numbers for Eπ sensors include:
- E300019160
- E300020260
- H56A7920001AC
If your sensor’s OE number matches any of these, the BL-ST-039 is a direct replacement.
Step 2: Check Your Vehicle’s TPMS Frequency
Eπ vehicles use a 433MHz TPMS system. You can confirm this by:
- Looking at your owner’s manual (TPMS section).
- Checking the sticker inside the driver’s door jamb (sometimes lists TPMS frequency).
- Using a cheap TPMS trigger tool to read the sensor frequency.
If your vehicle uses 315MHz or a different protocol, the BL-ST-039 will not work.
Step 3: Verify Clamp-in vs. Snap-in Design
The BL-ST-039 is a clamp-in sensor (metal valve stem secured with a nut from inside the wheel). Most Eπ models use clamp-in sensors, but some aftermarket replacements may be snap-in (rubber valve). If your vehicle originally had clamp-in sensors, stick with clamp-in. The BL-ST-039 fits standard 11.5mm valve holes.
Step 4: Confirm Pre-Programming Compatibility
The BL-ST-039 arrives pre-programmed to communicate with Eπ’s TPMS module. However, if your vehicle has been modified (e.g., aftermarket wheels, tire pressure monitoring system reset), you may need to relearn the sensor IDs. Most Eπ models support auto-relearn after driving 10–15 minutes above 25 km/h. If not, a TPMS tool will be needed.
What If the Sensor Doesn’t Fit?
If you’ve verified the OE number and frequency match, but the sensor still doesn’t communicate, check:
- Battery voltage: New sensor batteries should be 3V. Dead sensors won’t transmit.
- Valve stem angle: Some Eπ wheels have angled valve stems. The BL-ST-039 uses a straight metal stem; if your wheel requires a 45° or 90° angle, you’ll need an adapter.
- TPMS module software: Rarely, a dealer update can change the sensor protocol. Contact a Eπ service center if all else fails.
Recommended Part for Eπ TPMS Replacement
For most Eπ 007 and Eπ 008 owners, the BL-ST-039 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Aeolus, Eπ, Mhero, Nammi, Voyah | OE# E300019160, E300020260, H56A7920001AC is a reliable drop-in replacement. It matches the factory OE numbers and pre-programming, saving you the hassle of cloning or reprogramming. Just install and drive.
FAQ
Can I use the BL-ST-039 on a 2022 Eπ prototype or pre-production model?
Only if the vehicle uses a 433MHz clamp-in TPMS system. Pre-production models sometimes had different sensors. Check the OE number on the existing sensor—if it’s not one of the three listed (E300019160, E300020260, H56A7920001AC), the BL-ST-039 may not be compatible.
Do I need to reprogram the BL-ST-039 after installation?
No—the sensor is pre-programmed for Eπ vehicles. In most cases, the TPMS module will automatically recognize it after a short drive. If the warning light stays on, use a TPMS relearn tool or follow the manual’s reset procedure.
How long do these sensors last?
The internal battery typically lasts 5–7 years. The BL-ST-039 is a sealed unit (battery not replaceable), so you’ll need to replace the entire sensor when the battery dies.
Will this sensor work if I’m using aftermarket wheels?
Yes, as long as the wheels have a standard 11.5mm valve hole and the valve stem clears the wheel design. Angled valve stems may require a 90° adapter (not included).
