Cummins 2872277 Engine Camshaft Position Sensor

This Cummins camshaft position sensor (part numbers 2872277 and 3408529) is designed for ISBe 5.9L and ISBe6.7L 24V diesel engines. It supplies the engine control unit with real-time camshaft position data, enabling precise timing of valve operation and fuel injection. In 24V Cummins ISBe platforms, accurate cam timing information helps the ECM synchronize cam and crank signals, supporting reliable starting, smooth idle, and consistent power delivery. The sensor is a key component of the engine's timing system, and its data helps the ECM optimize ignition timing and combustion events across operating conditions. This part is identified by Cummins part numbers 2872277 and 3408529 and is intended for ISBe 5.9L and ISBe6.7L 24V installations. Use this sensor when replacing the original Cummins camshaft position sensor on these engines.
