Walker 256-1130 Engine Oil Pressure Switch

Engine Oil Pressure Switch for Land Rover

Walker 256-1130 is an OE replacement engine oil pressure switch built to monitor lubrication pressure and send the correct signal to the ECU or dashboard warning circuit. It is engineered for direct-fit service on select Land Rover applications, including Discovery, Freelander, and Range Rover models.

• OE replacement oil pressure switch for factory-style monitoring
• Steel body with steel finish for engine-bay durability
• Blade terminal design with oblong connector shape
• 1 terminal, male connector / female terminal interface
• Matches OE pressure threshold, thread size, and electrical response
• Direct installation at the original engine block or oil filter housing location

Built to Match Factory Specifications

Walker Products 256-1130 is manufactured to match OE requirements for pressure activation, terminal configuration, and physical fitment. The steel construction is paired with oil-resistant, high-temperature materials to handle continuous exposure in the lubrication system. For drivers searching for a Land Rover Discovery oil pressure switch, a Land Rover Freelander oil pressure switch, or a Range Rover oil pressure switch, this part provides the factory-style signal needed for accurate warning light operation and engine management input.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Symptoms This Part Can Address

• Oil warning light flickering or staying on
• False low-oil-pressure warnings
• No warning signal during an actual pressure drop
• Intermittent gauge or ECU input from the pressure circuit
• Faults caused by a worn or electrically inconsistent switch

Installation Notes

Fits 2002-2005 Land Rover Freelander, N/A. Fits 2000-2004 Land Rover Discovery, N/A. Fits 2000-2002 Land Rover Range Rover, N/A. Fits 1999 Land Rover Discovery, N/A, from chassis/VIN #XA231751. Fits 1999 Land Rover Range Rover, N/A, from chassis/VIN #XA426594.

Confirm thread engagement, connector style, and engine location before installation. Replace the switch only after verifying the oiling system condition, since a pressure switch reports pressure status but does not correct a mechanical lubrication problem.

Quality Assurance

Walker Products manufactures this oil pressure switch as an OE replacement component with application-specific electrical response and fitment details matched to the original design. Part number 256-1130 is built for direct replacement service on the listed Land Rover applications.
