Duralast Manifold Absolute Pressure (MAP) Sensor | SU10586 Accurate Boost Monitoring for 2008–2010 Ford 6.4L Powerstroke The Duralast SU10586 is a direct-fit replacement Manifold Absolute Pressure (MAP) sensor engineered to meet or exceed original equipment specifications. In a twin-turbocharged engine like the 6.4L Powerstroke, the MAP sensor is a critical component that measures intake manifold pressure (boost). This data is used by the PCM to calculate fuel delivery, turbo vane position, and EGR operation. A failing MAP sensor can lead to "limp mode," poor fuel economy, excessive black smoke, or a significant loss in power. Duralast sensors are designed with high-quality materials to withstand the extreme under-hood temperatures and vibration common in heavy-duty diesel applications. Key Features & Benefits Direct OE Replacement: Designed to match the fit, form, and function of the factory sensor (8C3Z-9F479-A) for a simple plug-and-play installation. Extensively Tested: Each sensor undergoes rigorous validation testing—including thermal cycling from -40°F to 300°F—to ensure reliable performance in extreme climates. Corrosion-Resistant Terminals: Built with sealed connections to prevent environmental corrosion, ensuring a clean electrical signal to the engine computer. Precision Pressure Reading: Restores accurate boost pressure data to help eliminate surging acceleration, rough idling, and MAP-related diagnostic trouble codes (DTCs). High-Quality Housing: Constructed from premium composite materials that resist cracking and internal component failure caused by engine vibration.

A plugged hose can often mimic a sensor failure by preventing the sensor from "seeing" the actual manifold pressure.
