Walker Products Engine Oil Pressure Switch P/N:256-1059
Keep an eye on engine lubrication with the Walker Products Engine Oil Pressure Switch 256-1104, an OE-replacement switch that monitors oil pressure and triggers a warning when levels fall below safe operating thresholds. It's a direct-fit replacement for the 1998-2000 Ford Contour, 2001-2007 Ford Escape, 2005-2007 Ford Five Hundred, 2005-2007 Ford Freestyle, 1999-2007 Ford Taurus, 2000-2005 Lincoln LS, 1999-2002 Mercury Cougar, 2005-2007 Mercury Mariner, 2005-2007 Mercury Montego, 1998-2000 Mercury Mystique and 1999-2005 Mercury Sable — see the "Vehicles it fits" section for the full engine-level list.
If a failed switch is the cause of a flickering oil light, false warnings, or no signal under actual low-pressure conditions, this unit replaces it and helps restore early warning within the lubrication system.
What does the Walker 256-1104 do?
It monitors engine oil pressure and activates the dashboard warning light or sends a signal to the ECU when pressure falls below safe operating thresholds.
Will this switch fit my vehicle?
It's a direct-fit replacement for applications such as the Ford Escape, Taurus, Contour, Lincoln LS, and several Mercury models. Check the "Vehicles it fits" section to confirm your exact year and engine.
What are signs this switch may need replacing?
Common signs include an oil light flickering, false warnings, or no signal under actual low-pressure conditions. Diagnose the cause before replacing, since low oil pressure can have other sources.
Does it require modifications to install?
No. It threads into the factory location using the original threads and connectors, so no modifications are required.
Is this an OE-quality part?
Yes. It's an OE-replacement switch calibrated to match original specifications for pressure activation point, thread pitch, and electrical response.
