Rear Headlight Level Sensor for Toyota Sequoia

Restore proper ride-height feedback with this Arnott rear headlight level sensor, part number RH-5258. It measures chassis-to-road distance and sends that information to the ECU so the air suspension system can adjust ride height as needed on the 2005-2007 Toyota Sequoia.

Key Features

• Arnott aftermarket ride height sensor for rear suspension leveling
• Black connector with square shape and male terminal design
• Standard grade replacement with one connector and one terminal
• New sensor construction for direct replacement service
• Fits 2005-2007 Toyota Sequoia, rear

Product Details

The Arnott RH-5258 is a rear headlight level sensor used in air suspension systems to report vehicle height changes to the ECU. When the control unit receives accurate height data, it can command the compressor and air struts to raise or lower the vehicle as required. This sensor is a direct-fit service part for Toyota Sequoia models from 2005 through 2007 and is referenced for the same application as OE part number 8940834010. The RH-5258 is built as a new replacement with a black, square connector, pin-style terminal, and male connector and terminal configuration.

Arnott RH-5258 is a practical replacement when the original rear level sensor on a Toyota Sequoia begins sending incorrect signals or stops responding. It supports consistent suspension height feedback for vehicles equipped with air suspension control logic.

Common Issues This Part Can Address

• Rear suspension sits too high or too low
• Inaccurate height readings sent to the ECU
• Air suspension compressor cycling at the wrong time
• Warning lights or suspension faults related to ride height sensing
• Sensor damage from road debris, water, salt, or impact

Installation Notes and Tips

Verify connector style, mounting location, and rear application before installation. Inspect the linkage, wiring, and surrounding suspension components for corrosion or damage, since a failed sensor can be caused by worn hardware or contamination in the area. After replacement, clear any stored suspension codes and confirm that the system responds correctly to height changes.

Quality Assurance

Arnott supplies aftermarket suspension components for vehicle-leveling systems, and this RH-5258 replacement is built as a new part for service use. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
