What tells the engine controller exactly when to fire each injector? The Cummins Camshaft and Crankshaft Position Sensor supplies the timing reference the engine control module needs before it will fire the injectors. A failed position sensor can cause hard starts, stalling, or a crank-no-start condition that keeps the truck parked. Plugging the Cummins 2872277 into the harness restores that timing signal, letting the controller fire the injectors on time and the engine start and run as it should.
