Arnott RH-3719 Rear Right Headlight Level Sensor
Arnott RH-3719 is a new rear right headlight level sensor for vehicles equipped with air suspension height monitoring. It measures chassis-to-road distance and sends that signal to the ECU so the system can adjust air pressure in the struts and maintain proper ride height.
Compatible With 2015-2020 Cadillac Escalade, rear right; 2015-2020 Cadillac Escalade ESV, rear right; 2015-2020 Chevrolet Tahoe, rear right; 2015-2020 GMC Yukon, rear right; and 2015-2020 GMC Yukon XL, rear right.

How It Works
This sensor monitors suspension height changes and relays that information to the vehicle control system. On Cadillac Escalade, Chevrolet Tahoe, and GMC Yukon air suspension setups, accurate sensor input helps the ECU command compressor and strut adjustments based on actual ride height. Arnott RH-3719 is built as an aftermarket replacement for the rear right sensor location.
Common Problems It Can Address
- Incorrect rear ride height readings
- Suspension warning lights related to height sensing
- Uneven vehicle stance at the rear
- Air suspension compressor cycling from faulty sensor input
- Damage from road debris, water, salt intrusion, or impact
Installation Notes
Verify the rear right mounting location before installation and compare the connector style, terminal count, and sensor shape to the original part. Inspect the linkage, mounting points, and wiring for corrosion or damage before replacing the sensor. After installation, clear any stored suspension codes and confirm the vehicle levels correctly.
Quality Assurance
Arnott supplies this as a new replacement sensor built for the listed applications. It cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.
