Compatible With 2007-2012 Lexus ES350 rear and 2005-2012 Toyota Avalon rear, this sensor supports accurate ride-height feedback for common OE-style air suspension applications.

Product Details
This ride height sensor helps the air suspension control system maintain proper vehicle stance by reporting suspension position to the ECU. When the sensor signal changes, the compressor can add or release air to keep the vehicle level. Arnott RH-5259 is a direct-fit style replacement for rear suspension use on the Lexus ES350 and Toyota Avalon applications listed below. This part cross-references Toyota 8940741010 for the same application.
What It Helps Address
- Uneven vehicle ride height
- Air suspension warning lights tied to sensor signal faults
- Incorrect compressor cycling caused by inaccurate height readings
- Suspension leveling problems after road debris or water intrusion damage
- Sensor wear from salt, corrosion, or impact exposure
Installation Notes
Verify the rear sensor location and connector style before installation. Inspect the linkage, mounting points, and wiring for corrosion or damage before replacing the sensor. After installation, clear any stored suspension fault codes and confirm the vehicle levels correctly during operation.
Quality Assurance
