This pressure sensor monitors system pressure in the electrical and fuel systems of the host tractor or combine. It converts hydraulic or pneumatic pressure into an electrical signal that the machine's control unit uses to adjust fuel delivery or activate warning circuits. A failed sensor can cause incorrect fuel metering, reduced engine power, or a persistent warning light. The sensor is manufactured by AGCO to match the original component's electrical output curve and thread fit, so the control unit receives the correct signal without recalibration. When replacing, ensure the mating connector is clean and the sealing O-ring is in good condition to prevent fluid ingress.
