Walker 256-1084 Engine Oil Pressure Switch

Walker 256-1084 Engine Oil Pressure Switch

Walker 256-1084 is an OE replacement engine oil pressure switch built to monitor lubrication pressure and send the proper signal to the ECU or dash warning circuit when pressure drops below safe limits. It is a direct-fit replacement for select Jeep Grand Cherokee and Ram applications, with OE-style thread size, terminal layout, and electrical response.

Built with metal and plastic construction, a black finish, a blade pin terminal, and a female connector with one terminal, this switch is made for factory-style connection at the engine block or oil filter housing. Walker 256-1084 helps restore accurate oil pressure monitoring on 2014-2019 Jeep Grand Cherokee, 2014-2018 Ram 1500, and 2019 Ram 1500 Classic models.

Key Features

• OE replacement engine oil pressure switch
• Monitors oil pressure and signals low-pressure conditions
• Matches OE specifications for pressure threshold and terminal type
• Metal and plastic construction for engine-bay exposure
• Blade pin terminal with female connector and male terminal
• Direct-fit design for factory mounting location
• Walker 256-1084 for Jeep Grand Cherokee and Ram oil pressure switch replacement

Detailed Description

This oil pressure switch is used in the engine lubrication warning circuit to report pressure status to the vehicle’s control system or instrument cluster. When the original switch wears out, the result can be flickering oil lights, false warnings, or no warning during an actual low-pressure event. Walker 256-1084 is engineered to match OE pressure settings, thread engagement, and electrical behavior so the replacement installs in the original location without modification. It is a practical choice for service work, drivability repairs, and engine rebuilds on Jeep Grand Cherokee and Ram trucks.

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

Common Issues This Part Can Address

• Oil warning light flickering at idle or during driving
• False low-oil-pressure warnings
• No dashboard warning when oil pressure is actually low
• Intermittent signal loss from a worn pressure switch
• Oil pressure monitoring faults after engine service

Installation Notes and Tips

Install the switch in the factory oil pressure port, typically on the engine block or oil filter housing, and connect it to the existing wiring harness. Verify thread size, connector style, and terminal orientation before installation. Confirm the oil system is at the correct level and inspect the harness and connector for corrosion or damage before replacing the switch.

Quality Assurance

Walker manufactures this switch to OE replacement standards using materials selected for heat and oil exposure in the engine compartment. The design follows factory-style fitment and electrical response for reliable oil pressure monitoring on the listed Jeep Grand Cherokee and Ram applications.
