Ride Height Level Sensors
A ride height sensor measures the position of the vehicle body relative to the suspension or axle, often through a small linkage. The vehicle's control module can use that signal for the equipment fitted to the vehicle.
A-Premium offers sensors for selected front and rear positions. Match the side, connector and suspension equipment before choosing a single sensor or a pair.
Choosing A Suspension Height Sensor
Linkage shape, mounting position and terminal arrangement can differ between applications. Some sensors are intended for a specific damping or leveling system, even when the vehicle model is the same.
Frequently Asked Questions (FAQ)
Can a ride height sensor also be used for headlight leveling?
On some vehicles, a level sensor supplies position information for automatic headlight adjustment as well as chassis controls. The correct part and function depend on the vehicle's equipment.
Does a new height sensor always calibrate itself?
Some systems require calibration or a basic setting after sensor or linkage work. Porsche and Freightliner describe calibration procedures for specified systems; follow the procedure for the vehicle.
Why does the sensor linkage orientation matter?
The lever must move through its intended range without binding or striking nearby components. Freightliner documents broken sensor arms caused by incorrect linkage or bracket installation on certain vehicles.
Can a three-terminal sensor replace a four-terminal sensor?
The electrical interface must match the system. A listed A-Premium front sensor pair uses three terminals, while a rear pair for a different application uses four.
Does a low corner always mean the height sensor has failed?
A low corner can also involve an air spring, a leak or another part of the leveling system. Inspect the suspension and sensor signal together rather than relying on vehicle stance alone.
