Walker 256-1207 Engine Oil Pressure Switch

Engine Oil Pressure Switch for Porsche

Walker 256-1207 is an OE replacement engine oil pressure switch built to monitor lubrication pressure and trigger the warning circuit when pressure drops below safe limits. It is a direct-fit solution for Porsche 911, 944, 928, 968, and 924 applications that rely on accurate oil pressure signaling.

• Metal housing for durable engine-bay service
• Matches OE pressure threshold, thread size, terminal type, and electrical response
• High-temperature, oil-resistant construction
• Direct replacement for factory mounting locations such as the engine block or oil filter housing
• Connects to existing wiring without modification

How It Works

This oil pressure switch sends a signal to the ECU or dashboard warning light when oil pressure falls outside the expected range. On Porsche 911, Porsche 944, and Porsche 928 applications, a failing switch can cause flickering oil lights, false warnings, or no warning at all during a real low-pressure event. Walker 256-1207 restores the factory-style pressure monitoring function with OE-matched electrical behavior and fitment.

Common Issues It Can Address

• Oil warning light flickering at idle or during driving
• False low-oil-pressure alerts
• No warning signal when oil pressure is actually low
• Intermittent gauge or ECU input from a worn switch
• Oil pressure monitoring faults during engine service or rebuild work

Installation Notes

Install the switch in the original threaded location and verify the terminal style matches the factory connector before installation. Clean the mounting area, inspect the wiring for corrosion or damage, and confirm proper oil pressure system operation after replacement. This part number, 256-1207, is a direct OE-style replacement for the listed Porsche applications.

Quality Assurance

Walker Products manufactures this switch to OE specifications for pressure response and fit. The design uses materials selected for prolonged exposure to heat and engine oil, supporting consistent warning-system performance in Porsche 924, 944, 928, 968, and 911 applications.
