The VX C-DM TPMS Reality Check
The VX C-DM is a modern plug-in hybrid crossover that relies on accurate tire pressure monitoring for safety and fuel efficiency. Its factory TPMS system uses 433MHz clamp-in sensors. When one fails (commonly after 5-7 years or battery depletion), you face the classic parts dilemma: pay dealer prices for an OEM sensor or trust an aftermarket alternative.
OEM vs Aftermarket: What Changes?
| Feature | OEM Sensor (Chery Genuine) | BH-Sens BL-ST-038 (Aftermarket) |
|---|---|---|
| Frequency | 433MHz | 433MHz |
| OE Numbers | 802000121AA, 802000126AA, F02361701001AA | Same OE cross-reference |
| Fitment | Direct bolt-on | Direct bolt-on, clamp-in |
| Programming | Pre-programmed or dealer-programmed | Pre-programmed (plug and play) |
| Typical Price | $45–$65 per sensor | $18–$25 per sensor |
| Warranty | 1–2 years (dealer dependent) | 1–2 years (BH-Sens) |
| Build Quality | OEM-grade | OEM-grade (Baolong Technology is an OE supplier) |
Baolong Technology (BH-Sens) is not a no-name brand. They supply sensors to several Chinese automakers, including Chery, which means the BL-ST-038 shares the same production line and quality control as the part that left the factory.
When OEM Is Actually Worth It
OEM sensors make sense in exactly two scenarios:
- Your VX C-DM is still under factory warranty – Using aftermarket parts may void TPMS-related warranty claims. Check your warranty terms.
- You need exact OE branding for resale – Some buyers prefer seeing the Chery logo on the sensor. If you’re selling the car soon, OEM may add perceived value.
Outside those cases, you’re paying a 150-200% markup for a sticker.
Price/Value: The Real Math
Replacing all four sensors on a VX C-DM with OEM parts runs roughly $180–$260 in parts alone. The BL-ST-038 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Chery, Chery Ev, Cowin, Exeed | OE# 802000121AA, 802000126AA, F02361701001AA set of four costs about $70–$100. That’s a $110–$160 savings for the exact same functionality.
Both options require the same installation procedure: mount the sensor, torque to the manufacturer spec (typically 35–45 in-lbs for clamp-in), and the car’s TPMS computer will recognize the pre-programmed signal. No special tools needed.
Installation Note
The BH-Sens BL-ST-038 is pre-programmed to match the VX C-DM’s factory TPMS protocol. This means you don’t need a TPMS tool to copy IDs—just install and drive. However, if you’re replacing only one sensor, verify the new ID matches the old one before finalizing the wheel installation.
FAQ
Can I mix OEM and aftermarket TPMS sensors on my VX C-DM?
Yes, as long as the frequency (433MHz) and protocol match. The BH-Sens BL-ST-038 is cross-referenced to the same OE numbers, so it will communicate with your vehicle’s TPMS module without issues. Mixing is perfectly safe.
How long do BH-Sens TPMS sensors last compared to OEM?
Both use similar lithium batteries rated for 5-7 years. BH-Sens sensors are built by Baolong Technology, a Tier 1 supplier, so lifespan is comparable. Early battery failure is rare; most failures are from physical damage during tire changes.
Do I need to reprogram the TPMS after installing BL-ST-038 sensors?
No. The BL-ST-038 is pre-programmed with the correct IDs for the VX C-DM. Once installed, the system should auto-learn within a few minutes of driving above 15 mph. If it doesn’t, a quick TPMS relearn procedure (often just a magnet or button sequence) may be needed—consult your owner’s manual.
Is the BH-Sens BL-ST-038 compatible with other Chery models?
Yes. It fits Chery, Chery EV, Cowin, and Exeed vehicles that use OE numbers 802000121AA, 802000126AA, or F02361701001AA. Always verify your vehicle’s OE part number before ordering.
