Specifications
The Automann 577.46328 Pressure Sensor is engineered for use in Freightliner diesel applications to monitor boost, manifold, or pressure differential in turbo systems. It is the same as Freightliner A4721531028, and is rated for a 0–7.98 psi operating range with a burst pressure of 39.8 psi. This sensor plays a critical role in engine control, sending analog signals to ECM to regulate boost, fuel delivery, and emissions systems. It’s offered through FleetPride as an Automann Multi-Purpose Pressure Sensor. With strong housing suited for harsh underhood environments, it’s a reliable replacement when original sensors fail or drift. Stengel Bros lists it as a standard replacement for Pressure Sensor Freightliner models.
