Understanding Nio TPMS Relearn
Nio electric vehicles use a direct TPMS system with 433MHz sensors. After replacing a sensor (e.g., the Nio BL-ST-051), the vehicle must learn the new sensor IDs. Nio supports three relearn methods, depending on your model year and available tools.
Method 1: Auto Relearn (No Tools Required)
The simplest method for most Nio models (2020–2025):
- Ensure all tires are inflated to the correct pressures (check your driver’s door sticker).
- Drive the vehicle above 25 mph (40 km/h) for 10–15 minutes.
- The system automatically detects and stores the new sensor IDs during this drive cycle.
- A TPMS warning light should turn off after successful relearn.
When it works best: After sensor replacement with identical OE-spec sensors (like the BL-ST-051) that are pre-programmed.
Method 2: OBD Relearn (Using a TPMS Tool)
For faster, more reliable results, use an OBD TPMS tool:
- Connect a compatible TPMS tool (e.g., Autel, Bartec, or Snap-on) to the OBD-II port.
- Follow the tool’s menu to select Nio → model year → “Relearn” function.
- Activate each sensor with the tool (hold near valve stem).
- The tool sends the new IDs to the vehicle’s ECU via OBD.
- Confirm the relearn is complete (tool shows “Success” or light turns off).
Tools required: Any TPMS tool that supports Nio (most aftermarket tools work with 433MHz sensors).
Method 3: Stationary Relearn (Infotainment Menu)
Available on newer Nio models (ET5, ET7, ES6, ES8 from 2022+):
- Park the vehicle, turn on ignition (no need to drive).
- Go to Settings → Vehicle → TPMS (or “Tire Pressure”).
- Select “Sensor Relearn” or “Learn New Sensors”.
- Follow on-screen prompts (may ask to activate each tire in sequence).
- Use a TPMS trigger tool to activate sensors at each wheel (LF, RF, RR, LR).
- Wait for confirmation on the infotainment screen.

Recommended Part
For a direct OE-fit replacement, use the BL-ST-051 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Nio, Onvo | OE# P0242518, P0302230, P0385734. It’s pre-programmed to Nio’s 433MHz protocol and includes the correct clamp-in hardware. No additional programming is needed before installation—just install and perform the relearn.
FAQ
How long does a Nio TPMS relearn take?
Auto relearn takes 10–15 minutes of driving. OBD relearn takes 2–5 minutes with a tool. Stationary relearn via infotainment takes about 5 minutes.
Do I need a special tool for Nio TPMS relearn?
Not necessarily—auto relearn works without tools. However, an OBD TPMS tool (Autel, Bartec, etc.) makes the process faster and more reliable, especially if you’re replacing multiple sensors.
Will the BL-ST-051 work on older Nio models?
Yes, if your Nio uses 433MHz TPMS (most models from 2018 onward). Check your owner’s manual or existing sensor for the OE number (P0242518, P0302230, or P0385734).
Can I mix different TPMS sensor brands on a Nio?
It’s not recommended. Nio systems expect consistent sensor IDs and protocols. Stick with OE-compatible sensors like the BH-Sens BL-ST-051 to avoid communication issues.
