Buick Century Power Steering Pressure Switch

The Buick Century Power Steering Pressure Switch is a small but very important sensor that prevents the engine from stalling every time the steering system requires maximum hydraulic force. Mounted in the high pressure line, this Power Steering Pressure Switch is constantly sampling the hydraulic flow. When it senses a surge while changing the speed of the vehicle to a slow speed, such as parking, it will instantly signal the engine control module to increase the idle speed to allow the motor to handle this additional load without faltering. Each Power Steering Pressure Switch must resist unrelenting fluid pulses that increase as engine rpm rises but respond immediately when the calibrated threshold is reached to maintain light steering effort. Earlier versions applied a simple on-off diaphragm that closed an electrical circuit at preset pressure. On earlier Century models, this simple design was effective, while later designs with variable assist layouts combined the signal from the Power Steering Pressure Switch with inputs from speed and steering angle sensors so electronic controllers could fine-tune pump flow to provide low speed ease as well as solid highway road feel. Regardless of style, the switch manages steering assistance with smooth idle, which means long-term Buick driving confidence is high as every Buick Century relies on a healthy Power Steering Pressure Switch.

Each OEM Buick Century 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.
