How much pressure is needed in auto power steering?

The pressure needed in an automotive Power Steering system typically ranges from 1,200 to 1,500 psi (pounds per square inch) when the system is under load. This pressure is generated by the power steering pump to assist with steering effort, especially during low-speed maneuvers. The exact pressure can vary based on the vehicle's make and model, as well as the design of the power steering system. Always refer to the vehicle's service manual for specific specifications.
