Walker 256-1021 Engine Oil Pressure Switch
Engine Oil Pressure Switch for Honda and Acura
Walker 256-1021 is an OE replacement engine oil pressure switch built to monitor lubrication pressure and send a warning signal when pressure drops below safe limits. It is a direct-fit replacement for many Honda Civic, Accord, Pilot, and Acura MDX applications, with OE-style electrical response and factory-style thread and terminal specifications.
Use Walker 256-1021 when the original oil pressure switch is causing false warnings, flickering oil lights, or no warning response during a real low-pressure condition. This switch is built with metal and plastic construction and a 3-terminal, female connector layout for direct connection to the existing harness.
Key Features
- OE replacement engine oil pressure switch
- Monitors oil pressure and signals the ECU or driver when pressure falls below safe limits
- Matches OE specifications for pressure threshold, thread size, terminal type, and electrical response
- Metal and plastic construction for engine-bay exposure
- 3-terminal design with 1 female connector and male terminals
- Direct-fit replacement for factory mounting locations on supported Honda and Acura vehicles
- Part number: 256-1021
Detailed Description
Walker 256-1021 is engineered for vehicles that rely on an oil pressure switch to trigger the dashboard warning light or provide a signal to engine management. It is built to match the original switch’s operating characteristics so the system can read oil pressure correctly and respond when lubrication pressure is out of range. This part number is used across a wide range of Honda and Acura models, including Honda Civic, Accord, Odyssey, Pilot, Ridgeline, and Acura MDX, TLX, and RDX applications. In supported vehicles, the switch installs at the factory location, including oil pump-mounted applications noted in the fitment data.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Oil warning light flickering or intermittent operation
- False low-oil-pressure warnings
- No warning signal when oil pressure is actually low
- Faulty switch readings that affect ECU or dash monitoring
- Replacement during engine service, drivability repair, or rebuild work
