Why TPMS Relearn Is Necessary on Fengon
When you install new TPMS sensors on a Fengon, the vehicle’s ECU does not automatically recognize them. Each sensor transmits a unique ID, and the system must learn these IDs and assign them to the correct wheel positions. Without a relearn, the TPMS warning light stays on, and tire pressure data remains unavailable.
TPMS Relearn Methods for Fengon
Fengon vehicles support three relearn procedures. Use the table below to choose the right method for your situation.
| Method | Tools Needed | Time Required | Best For |
|---|---|---|---|
| Auto Relearn | None (just driving) | 10–15 minutes | After tire rotation or sensor replacement |
| OBD Relearn | TPMS scan tool (e.g., Autel, Bartec, or Launch) | 2–5 minutes | Quickest and most reliable method |
| Stationary Relearn | TPMS trigger tool or strong magnet | 10–20 minutes | When OBD tool is unavailable |
Auto Relearn (Drive-Based)
This method works on most 2015+ Fengon models. After sensor replacement, drive the vehicle at a steady 20–40 mph for 10–15 minutes. The system automatically captures sensor IDs during this process. No tools needed—just a clear road. If the light remains on after 20 minutes, try another method.
OBD Relearn (Tool-Based)
- Connect a compatible TPMS scan tool to the vehicle’s OBD-II port (under the dashboard).
- Select “Fengon” and the model year (2008–2025 models are supported).
- Trigger each sensor by holding the tool near the valve stem (driver’s side front, passenger’s side front, passenger’s side rear, driver’s side rear).
- Follow the tool’s prompts to send the learned IDs to the ECU.
Most scan tools complete this in under 5 minutes. This is the recommended method for shops or DIYers who work on multiple vehicles.
Stationary Relearn (Magnet/Trigger Tool)
- Ensure all tires are inflated to the correct pressures.
- Set the parking brake and turn the ignition ON (engine off).
- Use a TPMS trigger tool or a strong neodymium magnet held against the valve stem.
- Activate each sensor in the correct sequence: LF → RF → RR → LR.
- Honk the horn once to confirm each sensor is learned.
- Turn the ignition OFF, then start the vehicle—the TPMS light should go out after a short drive.

FAQ
How do I know if my Fengon needs a TPMS relearn?
If the TPMS warning light stays illuminated after tire rotation, new sensor installation, or battery replacement, a relearn is required. The light may also flash for 60–90 seconds at startup, then stay solid.
Can I use any TPMS tool for Fengon OBD relearn?
Most universal TPMS tools from Autel, Bartec, and Launch support Fengon if they cover Asian brands. Check the tool’s vehicle coverage list—Fengon is often listed under “Dongfeng” or as a separate brand.
What happens if I skip the relearn?
The TPMS light remains on, and the system will not display tire pressures. Some models may also trigger a check engine light or disable other safety features. Always complete the relearn after sensor work.
Does the BL-ST-066 sensor work on other brands besides Fengon?
Yes.
