Walker 256-1104 Engine Oil Pressure Switch

Engine Oil Pressure Switch for OE-Style Monitoring

Walker 256-1104 is an OE replacement engine oil pressure switch built to monitor oil pressure and send the proper signal to the ECU or dashboard warning circuit when pressure drops below safe limits. It is a direct-fit replacement for a wide range of Volvo, Ford, Mazda, Lincoln, and Mercury applications, including Volvo S60, V70, XC70, and Ford Taurus models.

Built with a black plastic body, one female connector, and one male spade terminal, this switch is designed to match factory electrical response, thread size, and pressure threshold requirements. Walker 256-1104 installs in the original location on the engine block or oil filter housing and connects to the existing harness without modification.

Key Features

• OE replacement engine oil pressure switch
• Black plastic housing for factory-style fitment
• 1 female connector and 1 male spade terminal
• Matches OE pressure thresholds and electrical response
• Built with oil-resistant, high-temperature materials
• Direct replacement for select Volvo, Ford, Mazda, Lincoln, and Mercury vehicles

Detailed Description

The Walker 256-1104 oil pressure switch is used to monitor lubrication system pressure and trigger a warning light or control signal when pressure falls outside the normal range. Accurate pressure reporting is important on vehicles such as the Volvo S40, V50, XC90, and Ford Escape, where the switch helps the driver or ECU react quickly to a loss of oil pressure. Walker manufactures this part to OE specifications so the thread, terminal style, and switching behavior align with the original component.

This part cross-references applications commonly listed under Volvo and Ford oil pressure switch service needs, including 256-1104 for the same application.

What It Helps Address

• Oil warning light flickering or staying on
• False low-oil-pressure warnings
• No warning signal during an actual pressure drop
• Intermittent oil pressure switch electrical faults
• Drivability concerns tied to incorrect pressure input

Installation Notes and Tips

Install the switch in the factory oil pressure port, typically on the engine block or oil filter housing. Verify thread type, connector style, and terminal orientation before installation, especially on applications with 3/8" National Pipe Thread or 3/8" thread notes in the fitment data. Confirm the connector seats fully on the spade terminal and inspect the harness for corrosion or damaged wiring before final assembly.
