The “power” part of the steering comes in the form of pressurized fluid in steering rack passages that assist the driver in turning the wheels. The fluid also keeps everything cool and prevents damage in the metal-on-metal gear contact.
How does the power steering pressure switch work?
The power steering pressure switch communicates with the computer by sending information about the fluid in the power steering pressure system of the vehicle. From there, the computer adjusts the engine’s operation as needed. The switch has two electrical sensors, as well as a diaphragm,…
What should the fluid level be on a power steering rack?
