Front Right (Driver Side) Air Suspension Height Level Sensor for Tesla Model S/X (Up to 2022) | 1044941-00-B

1. Key Specifications & Compatibility

2. Why This Brand-Grade Sensor Is Critical for Your Air Suspension

1. Maintains a Level Ride: Detects if the front right side sags (e.g., from a heavy front passenger or cargo in the frunk) and sends real-time data to the suspension controller. The system then inflates/deflates the front-right air spring to balance the vehicle, preventing uneven tire wear and shaky steering—just as the original sensor would.
2. Enables Driving Mode Adaptability: Works seamlessly with "Comfort," "Sport," and "Highway" modes. It confirms the suspension lowers to reduce aerodynamic drag at high speeds or raises to clear rough roads, ensuring each driving mode functions as Tesla intended.
3. Protects High-Cost Components: Alerts the suspension system if the front-right suspension is overextended (e.g., hitting a deep pothole or curb), preventing damage to air springs, struts, or control arms—offering the same protective function as original parts.

3. What It Actually Does (No Tech Jargon)

• Constant Height Checks: 50 times per second, the sensor uses a built-in magnet to track how far the front-right suspension moves up or down. It sends this data to your Tesla’s suspension computer instantly—faster than a blink of an eye—so the system responds without delay.
• Fixes Sagging Automatically: If you have a passenger in the front right seat or load items in the frunk, the sensor notices the front right drop and signals the air spring to inflate. This keeps the car level, so your ride stays smooth and your steering doesn’t pull to one side.
• Tough Against Harsh Conditions: Rain, snow, salted winter roads, or high-pressure car washes won’t damage it. The IP6K9K rating ensures it handles even extreme weather and road grime without shorting out or losing accuracy.
• No Drifting Readings: Unlike low-quality generic sensors, this brand-grade digital sensor never "drifts" from its calibration. It delivers precise data every time, so the suspension reacts instantly to changes in load or road surface.

4. Signs Yours Needs Replacement

• Front Right Sagging: The front right side sits lower than the front left (check tire clearance above the wheel—you’ll see a visible gap difference).
• "Air Suspension Fault" Alert: Your touchscreen displays this warning, and the suspension may lock in "Safe Mode" (no height adjustments, limited speed).
• Unstable Ride: The front right bounces over small bumps, or the vehicle leans heavily to the right during turns (the sensor isn’t sending accurate data to the controller).
• Driving Modes Fail to Work: The suspension won’t lower for "Highway" mode or raise for "Off-Road" mode (the sensor can’t confirm the suspension reaches the required height).
• Random Height Changes: The front-right air spring inflates or deflates unexpectedly (the sensor is sending false data to the suspension system).

5. Why This Brand-Grade Sensor Outperforms Generic Alternatives

• Tesla-Spec Calibration: Programmed with the exact height thresholds Tesla uses for Model S/X (up to 2022). No "false fault" alerts— a common issue with generic sensors that don’t match Tesla’s software.
• Perfect, Tool-Free Fit: Mounts to the front-right control arm and chassis using factory-drilled holes—no drilling, grinding, or zip-ties needed. The 3-pin connector plugs directly into the original wiring harness (no wire cutting), just like original components.
• Durable Construction: The sensor housing is made of glass-filled nylon (resists impact from road debris), and the electrical connector has anti-corrosion plating (prevents rust from road salt and moisture). It’s built to last as long as original parts, without premature wear.
• Consistent Accuracy: Hall-effect technology avoids wear-related drift (a problem with analog generic sensors). This brand-grade sensor maintains ±0.5mm accuracy for long-term use, while generic options often lose precision after short periods.
