Walker Products 256-1131 Engine Oil Pressure Switch

Walker Products 256-1131 Engine Oil Pressure Switch. Walker Products 256-1131 Engine Oil Pressure Switch. Walker Products Engine Oil Pressure Switches are OE Replacement components engineered to monitor oil pressure and alert the ECU or driver when levels fall below safe limits. These switches serve as critical warning devices that activate dashboard lights or feed signals to engine control systems when oil pressure drops, helping prevent severe internal damage due to lack of lubrication. Common symptoms of failure include oil light flickering, false warnings, or lack of signal under actual low-pressure conditions. Walker switches are manufactured to match OE specifications for pressure thresholds, thread size, terminal type, and electrical response. Each unit is built with high-temperature and oil-resistant materials to ensure consistent performance under prolonged engine exposure. Designed for exact OE fit, these switches thread directly into the factory location—typically the engine block or oil filter housing—and connect to existing wiring with no modifications. Whether used as part of a scheduled service, drivability repair, or engine rebuild, Walker Oil Pressure Switches provide dependable pressure monitoring and help extend engine life by maintaining early warning functionality within the lubrication system.
