Cadillac Deville Power Steering Pressure Switch

The Cadillac Deville Power Steering Pressure Switch monitors stress in the hydraulic line. It transmits a signal to the engine control unit, so idling speed rises just enough to not stall. At lower speeds, the steering pump strains. The Power Steering Pressure Switch, which is located close to the pressure hose, will close when fluid pressure increases. It will then send an electrical signal to the computer to indicate that additional torque is required. The switch opens again once the load lessens. This happens within milliseconds to allow the driver to steer with minimal effort while keeping the engine running smoothly. The early Deville models had a simple two-state Power Steering Pressure Switch that merely completed or broke a circuit. Later Cadillac sedans adopted variable-assist steering where the same Power Steering Pressure Switch feeds data to modules that also watch the vehicle speed and steering angle for a lighter parking feel without the loss of high-speed road feedback. Present-day Cadillac owners depend on this little protector because the Power Steering Pressure Switch shields the pump components from excessive pressure, stabilizes idle, and helps every Deville operator make confident, low-effort turns in the city and tight parking spots.

Each OEM Cadillac Deville Power Steering Pressure Switch we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
