Keep an early warning on your engine's lubrication system with the Walker Products Engine Oil Pressure Switch 256-1263. This OE-replacement switch monitors oil pressure and signals the driver or ECU when pressure falls below safe operating limits, helping protect against low-oil conditions. It's a direct-fit replacement for the 1995 and 1997 Land Rover Defender 90, 1995-1999 Land Rover Discovery, and 1995-1999 Land Rover Range Rover — see the Buyer's Guide tab for engine-level details.
Monitors oil pressure levels: Activates a dashboard warning or ECU input when oil pressure drops below safe operating thresholds.
Helps protect the engine: Alerts the driver or system to low oil pressure so you can address a lubrication problem before it causes damage.
OE-replacement calibration: Matches original specs for pressure activation point, thread pitch, and electrical response.
Built for harsh conditions: Made to resist high temperatures, oil exposure, and vibration in demanding engine environments.
Designed for exact OE fit, the switch threads into the factory location — typically the engine block or oil filter housing — and connects to the existing wiring with no modifications. Signs the original switch may need replacing include a flickering oil light, false warnings, or no signal under genuine low-pressure conditions.
