Walker Fuel Pressure Sensor 254-1009

Walker 254-1009 is an OE replacement fuel pressure sensor built to deliver accurate, real-time fuel pressure data to the ECM. It supports proper fuel trim, injector timing, combustion control, and emissions system operation on gasoline and diesel applications.

Key Features

  • OE-style fuel pressure sensor for factory fuel management systems
  • Matches OE pressure range, electrical output, and connector design
  • 3-terminal pin design with female connector and male terminals
  • Oblong connector shape for direct-fit installation
  • Built for heat, vibration, and fuel system pressure exposure
  • Direct replacement for select Chevrolet, GMC, Buick, and Cadillac applications

Product Details

This Walker fuel pressure sensor is engineered to provide the ECM with stable pressure feedback so the engine can maintain correct fueling under changing load and operating conditions. The sensor is designed to communicate with factory fuel management systems using OE-matched specifications, helping preserve drivability and emissions performance. Walker 254-1009 is a direct-fit replacement for a wide range of vehicles, including Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Impala applications.

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

Common Issues This Part Can Address

  • Check engine light related to fuel pressure sensor faults
  • Fuel pressure signal errors reported by the ECM
  • Rough idle or drivability concerns tied to incorrect fuel delivery data
  • Injector timing or fuel trim problems caused by inaccurate pressure readings
  • Emissions system faults linked to fuel system monitoring

Installation Notes

Verify connector shape, terminal count, and fuel system location before installation. This sensor uses a 3-terminal pin layout with an oblong female connector and male terminals. Confirm the vehicle application and sensor position, including low-pressure or at-fuel-pump configurations where listed, before replacing the original unit.

Quality Assurance

Walker Products designs these fuel pressure sensors as OE replacement components and tests them for long-term performance under heat, vibration, and fuel pressure exposure. The part number is 254-1009.
