Type 

Height sensor: Hall sensor with magnet in rotor, ASIC, that detects the angle of the magnetic field. Output signal 0 - 5 V is proportional to angle. Measurement range: -35° to +35°.

characteristic 

Height sensor: Voltage between terminals #1 and #2 should be approx. 2.5 V at rest and when vehicle is stationary. Voltage fluctuates around this value during vertical movements.

Other information 

Height sensors on the right and left side have differing output signals during compressed/extended suspension. During compressed suspension, the sensors on the left side have a signal of about 0.5 V while those on the right have a signal of approx. 4.5 V. During extended suspension, sensors on the left side have a signal of approx. 4.5 V while those on the right have approx. 0.5 V.
