Walker 256-1150 Engine Oil Pressure Switch
Walker 256-1150 Engine Oil Pressure Switch
Walker 256-1150 is an OE replacement engine oil pressure switch built to monitor lubrication pressure and send the correct signal to the ECU or dashboard warning circuit. It is engineered for Audi applications that rely on accurate oil pressure feedback, including Audi A6 allroad, A8 Quattro, Q7, Q8, RS6 Avant, RS7 Sportback, S8, SQ7, and SQ8 coverage.
Built with metal and plastic construction, a green housing, and a blade pin terminal layout, this switch is designed to match factory electrical response, thread size, and pressure threshold requirements. The Walker 256-1150 oil pressure switch connects through a single female connector with a male terminal interface for direct OE-style replacement.
Key Features
- OE replacement engine oil pressure switch for factory-style oil pressure monitoring
- Matches OE specifications for pressure threshold, thread size, terminal type, and electrical response
- Metal and plastic construction for engine-bay durability
- Blade pin terminal design with 1 connector and 1 terminal
- Direct-fit replacement for select Audi models, including Audi A6 Quattro, A7 Sportback, S5, and SQ5
- Walker part number 256-1150 for service and repair identification
Detailed Description
The Walker Products engine oil pressure switch is built to restore accurate oil pressure signaling in vehicles where the warning lamp or ECU depends on a stable electrical input. When oil pressure drops below the calibrated limit, the switch sends the signal needed to trigger the warning system, helping maintain proper engine protection. This makes it a practical replacement for Audi vehicles such as the A6 Quattro, A8 Quattro, Q7, RS5, S6, and SQ5, where precise oil pressure monitoring is critical.
Walker 256-1150 is manufactured to OE-style dimensions and electrical behavior so it threads into the factory location and connects to existing wiring without modification. The high-temperature, oil-resistant construction is suited for long-term exposure in the engine environment. This part cross-references no listed aftermarket numbers for the same application.
What It Helps Address
- Oil warning light flickering or intermittent illumination
- False low-oil-pressure warnings
- No warning signal during an actual low-pressure condition
- Faulty oil pressure input to the ECU or instrument cluster
- Drivability concerns tied to incorrect lubrication-system feedback
Installation Notes and Tips
Install the switch in the factory oil pressure port, typically on the engine block or oil filter housing, and verify the connector locks securely to the terminal. Confirm the replacement matches the OE pressure threshold and terminal style before installation. For Audi fitment, verify the application by year, model, and engine configuration against the vehicle’s original switch.
Quality Assurance
Walker manufactures this oil pressure switch to OE replacement standards for fit, electrical response, and durability. The design uses materials selected for heat and oil exposure in engine service, supporting consistent pressure monitoring in daily driving and repair applications.
