AUTOMANN Air Inlet Manifold Pressure Sensor Part No: 577.99521

The Automann 577.99521 Air Inlet / Manifold Pressure Sensor is a strong MAP (Manifold Absolute Pressure) unit intended for Caterpillar engine families, including C10, C12, C15, C16, and 3406E. Its specifications include a 3-pin connector, a 16.50-inch cable, and a 7/16-20 male thread for secure mounting. It is catalogued under cross references 1946724, 1298374, and 1619929. This sensor translates intake manifold air pressure into electrical signals, which are critical to the engine control unit’s calculation of air density and optimal fuel delivery. On turbocharged engines, this helps determine boost control, EGR functions, and ensures the engine responds properly under varying load and altitude. Wofford Truck Parts offers this sensor as a reliable replacement for fleets and repair shops servicing Cat engines that require precise intake pressure measurement.
