Walker Products Exhaust Gas Differential Pressure Sensor P/N:274-1009

Walker Products 274-1009 Exhaust Gas Differential Pressure Sensor

Walker Products Exhaust Gas Differential Pressure Sensors are OE Replacement components that monitor DPF efficiency to support emissions control and regeneration accuracy.

• Walker Products Exhaust Gas Differential Pressure Sensors are precision-engineered OE Replacement components designed to measure the pressure differential across the diesel particulate filter (DPF). This critical data is used by the engine control module (ECM) to determine the appropriate timing for regeneration cycles, reduce soot buildup, and maintain compliance with emissions standards. Walker sensors help detect clogging conditions early to prevent drivability issues and protect against costly engine derate events. Built to operate in the harsh exhaust environment, each sensor features a rugged construction that resists high temperatures, vibration, and soot contamination. These units are manufactured to meet or exceed OE specifications for pressure range, signal accuracy, and electrical performance. With exact OE fit and factory-matched connectors, installation is quick and seamless across a wide range of diesel applications. Trusted for light-duty and medium-duty diesel platforms, Walker Exhaust Gas Differential Pressure Sensors deliver accurate, reliable data for clean engine performance and long-term emissions system durability.
