A height sensor is fitted in each corner of the vehicle to monitor the ride height of the vehicle. The sensors are mounted 
on the front and rear subframes, with a mechanical link to the suspension lower arms. There are six different types of 
sensor fitted to Range Rover:

l

LH front height sensor – All vehicles

l

RH front height sensor – Halogen headlamps fitted

l

RH front height sensor – Xenon headlamps fitted

l

LH rear height sensor – All vehicles.

l

RH rear height sensor – Halogen headlamps fitted

l

RH rear height sensor – Xenon headlamps fitted.

NOTE: RH front and RH rear height sensors fitted to vehicles with Xenon headlamps have a white stripe across the 
back face of the sensor housing for identification.

The height sensors are attached to brackets on the subframes and are connected to the lower arms by links. The links 
allow articulation of the arm to allow for suspension travel. Each sensor is connected by a six pin multiplug. Standard 
height sensors use three of the six pins and height sensors for vehicles fitted with xenon headlamps use all six.

The height sensors contain a circuit board with a Hall effect sensor. The sensor is supplied with a reference voltage 
from the air suspension ECU which measures the returned voltage to determine the sensor arm position. The sensors 
used on vehicles with xenon headlamps use a sensor with a second circuit. This second circuit is used by the xenon 
headlamp levelling ECU.

The front sensor ball jointed linkage is a serviceable item. The rear sensor linkage cannot be serviced and must be 
changed as a complete assembly.
