Arnott Industries Headlight Level Sensor,Suspension Ride Height Sensor P/N:RH-5059
Help your Lexus sit level and respond to the road with the Arnott Industries Suspension Ride Height Sensor RH-3763, also listed as a Headlight Level Sensor. This front left sensor is a direct-fit replacement for the 2008-2016 Lexus LS600h (engine: All) and the 2009-2017 Lexus LS460 (engine: All).
Arnott's OES ride height sensors are designed to help level the vehicle by measuring the changing distance between the road and the chassis. That reading goes to the Electronic Control Unit (ECU), which signals the air suspension compressor to add or release air in the air struts as needed.
Ride height sensors can wear out and are exposed to road debris, collisions, and water and salt intrusion. Replacing a worn sensor is intended to help prevent further damage to the air suspension system. Signs one may need replacing include a suspension warning light, an uneven or incorrect ride height, or a vehicle that no longer levels as it should. For best results, Arnott recommends replacing ride height sensors in pairs. This listing is for one sensor. Country of origin: Japan.
