Arnott Industries Headlight Level Sensor,Suspension Ride Height Sensor P/N:RH-3703
Arnott Industries RH-3776 rear right headlight level sensor for the 2010-2023 Lexus GX460 measures the distance between the road and the chassis. The ECU uses that reading to tell the air suspension compressor to add or release air in the air struts.
A suspension warning light or a rear end that sits at the wrong height can mean this sensor is worn, though the air suspension compressor or an air strut can be behind the same signs, so find the cause first.
It is a direct-fit replacement for the 2010-2023 Lexus GX460, with one sensor at the rear right. This listing is a single sensor for that position; the left side is ordered separately, and for best results the two are replaced as a pair.
