Maintain peak performance in your semi trucks, big rigs, and commercial vehicles with the FleetRun FR-AFTR797 DPF Pressure Sensor, a direct replacement for Volvo 20451992. This critical diesel aftertreatment sensor measures differential pressure across the Diesel Particulate Filter (DPF) to ensure accurate regeneration cycles, reduce emissions, and prevent costly downtime for your heavy-duty fleet trucks.
