Height Sensors

The Height Sensors are variable resistors or potentiometers mounted on the chassis and activated by links to the front radius arms and rear trailing links. As height of an air spring changes, height sensor output signal voltage changes due to varying resistance. The sensor's output voltage increases as height is lowered and decreases as height increases. The Air Suspension ECU monitors sensor's output signals to determine what action is required to obtain correct vehicle height. In case of height sensor failure, the assembly must be replaced.
