Walker 256-1088 Engine Oil Pressure Switch

Engine Oil Pressure Switch Overview

Walker 256-1088 is an OE replacement engine oil pressure switch built to monitor lubrication pressure and send a warning signal when pressure drops below safe limits. It is a direct-fit solution for a wide range of Honda, Acura, and select Isuzu applications, including Fits 1985-2007 Honda Accord, N/A and Fits 2003-2009 Honda Element, N/A.

• OE replacement oil pressure switch for factory-style pressure monitoring
• Matches OE specifications for pressure threshold, thread size, terminal type, and electrical response
• High-temperature, oil-resistant construction for engine bay exposure
• Direct-thread design for factory mounting locations
• Walker 256-1088 supports dashboard warning lights and ECU signal input

Detailed Fitment and Function

This oil pressure switch is used to detect low oil pressure and trigger the warning system before lubrication loss can lead to internal engine damage. Walker 256-1088 is engineered for exact OE fit and is listed across multiple Honda Accord, Honda Civic, Acura TL, Acura MDX, and Honda Pilot applications. The switch uses a screw terminal with one male connector and one female terminal, and its metal/plastic body is built for consistent electrical response under heat and oil exposure. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Oil light flickering or intermittent warning behavior
• False low-pressure alerts from a worn switch
• No signal when oil pressure actually drops
• Electrical connection issues at the factory oil pressure circuit
• Pressure monitoring faults during service or engine repair

Installation Notes

Fits 2006-2008 Honda Pilot, N/A with location-oil pump notes, and other listed applications with factory-style threaded mounting. Verify thread diameter, terminal style, and connector configuration before installation. The switch threads directly into the original location and connects to existing wiring without modification when the vehicle application matches the catalog listing.

Quality Assurance

Walker Products manufactures this switch to OE specifications for fit, pressure response, and electrical performance. The design uses high-temperature, oil-resistant materials to support reliable operation in the lubrication warning circuit.
