Product Details

Walker Products has supplied fuel system and engine sensor components since 1946, with manufacturing and engineering support focused on meeting or exceeding OEM standards and specifications. The Walker Products line includes engine management parts such as sensors, injectors, and ignition-related components, backed by ISO 9001/IATF16949 certified quality systems. This MAP sensor is intended for vehicles that require a precise manifold pressure signal to the engine control system, including Ford E-350 Super Duty, Ford F-250 Super Duty, Ford F-350 Super Duty, and Ford Excursion applications listed above. This part cross-references Delphi PS10231 for the same application.

Common Issues This Sensor Can Address

• Erratic idle caused by incorrect manifold pressure input
• Hard starting related to faulty engine load sensing
• Reduced throttle response from inaccurate MAP readings
• Check engine light conditions tied to sensor signal faults
• Fuel trim and drivability problems from a failing pressure sensor

Installation Notes

Verify the vehicle year, model, and engine-management configuration before ordering. Compare the connector style and mounting location on the original sensor to confirm a proper replacement. After installation, clear diagnostic trouble codes and confirm stable idle, throttle response, and sensor data with a scan tool.
