Understanding McLaren TPMS Relearn
Mclaren vehicles, like many high-performance marques, use direct TPMS sensors mounted inside each wheel. When you replace a sensor or rotate tires, the system must learn the new sensor IDs. McLaren generally supports three relearn methods: auto relearn, OBD relearn, and stationary relearn. Which one works depends on your model year and whether you have the proper tools.
Relearn Methods for McLaren
Auto Relearn (No Tools Required)
This is the simplest method and works on most McLaren models from 2015 onward.
- Ensure all tires are inflated to the recommended pressure (check your owner’s manual).
- Drive the vehicle above 25 mph (40 km/h) for 10–20 minutes continuously.
- The system automatically detects the new sensor IDs during this drive cycle.
If the TPMS warning light turns off after driving, the relearn is complete. If not, move to the OBD method.
OBD Relearn (Using a TPMS Programming Tool)
For models that do not support auto relearn, or after a sensor replacement that fails to sync, an OBD2 relearn tool is needed.
- Connect a compatible TPMS programming tool (e.g., Autel, Bartec, or ATEQ) to the OBD2 port under the dashboard.
- Select “McLaren” and the correct model year.
- Follow the tool’s prompts to trigger each sensor (some tools require a trigger wand near each tire valve stem).
- The tool will write the new sensor IDs to the vehicle’s ECU.
This method typically takes 5–10 minutes and is the most reliable.
Stationary Relearn (LF Trigger Tool)
Some older McLaren models (pre-2015) require a stationary relearn using a Low Frequency (LF) trigger tool.
- Park the vehicle and turn the ignition to “ON” (engine off).
- Use an LF trigger tool (part of many TPMS tool kits) placed against the tire sidewall near the valve stem.
- Activate the tool for each tire in a specific sequence (usually LF front, RF front, RR rear, LR rear).
- The horn will chirp once per sensor learned.
Check your vehicle manual for the exact sequence, as it varies by model.
Sensor Compatibility: Why the BH-Sens RDE048V21 Fits McLaren
McLaren uses 433MHz TPMS sensors across most models, including MP4-12C, 650S, 720S, and Artura. The RDE048V21 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Aston Martin, Audi, BMW, Bentley, Bugatti & 9 More | OE# 11B0015CP, 11B0022CP, 2000680 is a direct replacement with OE cross-references such as 11B0015CP, 11B0022CP, and 2000680. Always confirm your model year before purchasing—sensor shape and valve stem type may differ between early and late models.
| McLaren Model | Typical Year Range | TPMS Frequency | Compatible Sensor |
|---|---|---|---|
| MP4-12C | 2012–2014 | 433MHz | RDE048V21 |
| 650S | 2014–2016 | 433MHz | RDE048V21 |
| 720S | 2017–2023 | 433MHz | RDE048V21 |
| Artura | 2022+ | 433MHz | RDE048V21 |
Tools You’ll Need
- TPMS trigger tool (for stationary relearn) or OBD2 programming tool (for OBD relearn)
- Tire pressure gauge
- Optional: TPMS cloning tool if you want to copy original sensor IDs

FAQ
How do I know if my McLaren needs a TPMS relearn?
If the TPMS warning light stays on after inflating tires to proper pressure and driving for 20 minutes, a relearn is needed. The light may also flash for 60–90 seconds on startup if sensor IDs are missing or wrong.
Can I reuse my old TPMS sensors on new wheels?
Yes, as long as the sensors are undamaged and the batteries are not depleted (TPMS sensor batteries typically last 5–7 years). You will still need to perform a relearn after moving them to different wheels.
What happens if I skip the relearn?
The TPMS light will remain on, and the system will not display correct tire pressures. On some McLaren models, this may also disable certain driver-assist features related to tire monitoring.
Is the OBD relearn method safe for my McLaren’s electronics?
Yes, when using a reputable TPMS tool designed for European vehicles. These tools only communicate with the TPMS module and do not affect engine or transmission electronics.
