Detailed Description

The Walker 256-1181 engine oil pressure switch is engineered for accurate oil pressure monitoring in Saab 900, Saab 9000, and 1999 Saab 9-3 vehicles. It provides the signal needed to activate the warning light or communicate low-pressure conditions to the engine control system, helping maintain early warning function in the lubrication circuit. This part number is built to OE-style dimensions and electrical characteristics so it installs in the original location without modification.

For drivers searching for a 1999 Saab 9-3 oil pressure switch or a replacement oil pressure switch for 1986-1998 Saab 900 and 1987-1998 Saab 9000 models, Walker 256-1181 offers the correct spade terminal layout and factory-style fit. This part cross-references Standard Motor Products (e.g., PS-100, PS-101) for the same application.

What It Helps Address

• Oil warning light flickering or staying on
• False low-oil-pressure warnings
• No warning signal when actual oil pressure is low
• Faulty oil pressure switch signal to the ECU or dash indicator
• Drivability concerns caused by inconsistent pressure monitoring

Installation Notes and Tips

Install Walker 256-1181 in the factory oil pressure switch location and connect it to the existing wiring harness using the original spade-style terminal. Verify thread engagement and electrical connection before starting the engine. Because oil pressure switch locations can vary by engine configuration, confirm the original part style and connector type against the removed component before installation.

Quality Assurance

Walker Products manufactures this switch to OE replacement standards using materials selected for heat and oil exposure in the engine bay. The design follows factory-style pressure response and connector specifications for dependable operation in Saab 900, Saab 9000, and 1999 Saab 9-3 applications.
