Tesla Model X TPMS Overview
The MODEL X uses a direct TPMS system where each wheel has a sensor transmitting real-time tire pressure data to the vehicle’s onboard computer. Unlike some vehicles that require dealer programming, the Tesla system can auto-learn compatible sensors after installation. However, not all third-party sensors work — compatibility depends on frequency, protocol, and whether the sensor supports Tesla’s specific TPMS software.
The BH-Sens RDE255V26 is designed specifically for Tesla vehicles and uses Baolong Technology’s 2.4GHz frequency, which matches the later Model X TPMS systems. This is important because earlier Model X models (2016–mid-2018) may use 433MHz sensors, while later models (mid-2018–2020) transitioned to 2.4GHz.
Compatible Year Coverage for Model X
The RDE255V26 BH-Sens sensor fits the following Tesla Model X years:
| Model Year | Compatibility | Notes |
|---|---|---|
| 2016 | Check frequency | Early production may use 433MHz; verify sensor part number |
| 2017 | Check frequency | Mid-2017 onward likely compatible |
| 2018 | Most models | Late 2018 models use 2.4GHz |
| 2019 | Full compatibility | All Model X use 2.4GHz |
| 2020 | Full compatibility | Up to late 2020 production |
Note: Tesla made a mid-cycle TPMS change around 2018. If your Model X was manufactured before July 2018, you may have 433MHz sensors. After July 2018, 2.4GHz sensors are standard.
How to Verify Fitment Before Buying
Step 1: Check Your Current Sensor Part Number
Open your Tesla’s TPMS settings screen (Controls > Service > TPMS). Each sensor has a unique ID. Write down the sensor IDs or check the physical sensor on your wheel for the OE number. Common Tesla Model X OE numbers include:
- 149070100B
- 149070100C
- 149070100D
- 149070100E
- 149070101B
- 149070101C
- 149070101D
- 149070101E
If your current sensor shows any of these numbers, the BH-Sens RDE255V26 is a direct replacement.
Step 2: Identify Your Vehicle’s Production Date
Look at the driver’s side door jamb sticker for the month/year of manufacture. If your Tesla was built between July 2018 and 2020, the 2.4GHz BH-Sens sensor will work. For earlier models, you may need a 433MHz variant.
Step 3: Verify Frequency Using a TPMS Tool (Optional)
If you have access to a TPMS scan tool (like Autel or Bartec), scan the sensor on your current wheel. The tool will display the frequency. If it reads 2.4GHz, the BH-Sens sensor is compatible. If it reads 433MHz, you need a different sensor.
Step 4: Confirm the Sensor is Pre-Programmed
The BH-Sens RDE255V26 is pre-programmed with Tesla-compatible firmware. This means it does not require cloning or additional programming — install it, drive the car at 20+ mph for several minutes, and the TPMS system should auto-learn the new sensor IDs.
Why Frequency Matters
Tesla Model X uses two different TPMS frequencies:
- 433MHz: Used on early Model X (2016–mid-2018). These sensors are not compatible with 2.4GHz systems.
- 2.4GHz: Used on later Model X (mid-2018–2020). The BH-Sens RDE255V26 operates at this frequency.
Installing a 2.4GHz sensor in a 433MHz system will result in no communication — the TPMS light will stay on, and pressure readings will not display. Conversely, installing a 433MHz sensor in a 2.4GHz system will also fail.
Installation Tips
- The BH-Sens RDE255V26 is a clamp-in type sensor. It replaces the existing sensor and valve stem assembly. Use a new metal valve stem and torque the sensor nut to manufacturer specifications (typically 4.5–6 Nm — check your manual).
- After installation, inflate the tires to the recommended pressure (usually 42–45 psi for Model X).
- Drive the vehicle for 10–15 minutes at speeds above 20 mph. The TPMS system should automatically recognize the new sensors. If the light remains on, cycle the ignition or perform a TPMS reset via the touchscreen (Settings > Service > TPMS > Reset).
Recommended Part
For owners of 2018–2020 Tesla Model X, the RDE255V26 | BH-Sens 2.4GHz TPMS Tire Pressure Sensor | Fits Tesla | OE# 149070101B, 149070100B, 149070101C is a reliable, direct-fit replacement. It covers OE numbers 149070100B through 149070101E and comes pre-programmed for plug-and-play installation. This sensor eliminates the need for dealer visits or expensive OEM parts.
FAQ
Will the BH-Sens RDE255V26 work on a 2016 Tesla Model X?
It depends on the production month. If your 2016 Model X has the 2.4GHz TPMS system (rare but possible on very late 2016 models), yes. However, most 2016 Model X vehicles use 433MHz sensors. Check the sensor’s part number on the wheel — if it matches one of the OE numbers listed above, it is compatible. Otherwise, you likely need a 433MHz sensor.
Do I need to program the BH-Sens sensor after installation?
No. The RDE255V26 is pre-programmed with Tesla-specific firmware. After installation, the vehicle will auto-learn the sensor ID during normal driving. There is no need for a TPMS tool or dealer programming.
How do I know if my Tesla Model X uses 2.4GHz or 433MHz?
Check the service menu on your touchscreen (Controls > Service > TPMS). The sensor IDs displayed will correspond to the frequency. You can also look at the physical sensor — 2.4GHz sensors often have a “2.4G” marking. Alternatively, use a TPMS scan tool to read the frequency directly.
Can I use this sensor for all four wheels?
Yes. The BH-Sens RDE255V26 works on all wheel positions (left front, right front, left rear, right rear). Tesla Model X does not have position-specific sensors — the system learns which sensor is on which wheel automatically.
