This disclosure describes techniques for determining a state of a pressurized chamber of a suspension of a vehicle, wherein the pressurized chamber comprises a hydraulic fluid chamber and a gas chamber separated by a piston. The state is determined by varying a pressure in the hydraulic fluid chamber and determining a knee point in a change of pressure in the hydraulic fluid chamber. The knee point indicates that the separator has been bottomed out. The pressure in the knee point may be used to determine a state of the suspension system.
