General Motors 8973650380 Camshaft Position Sensor

The 8973650380 camshaft position sensor is a Hall-effect magnetic sensor designed to monitor camshaft rotational position and speed for the engine control module (ECM). It provides a digital square-wave signal critical for sequential fuel injection timing and ignition control on 6.6L Duramax V8 diesel engines. Constructed with a high-temperature resistant polymer housing and sealed connector interface to withstand underhood vibration, thermal cycling, and contamination exposure. Direct bolt-on mounting flange ensures precise air gap alignment with the camshaft reluctor wheel. Manufactured to OEM specifications for signal accuracy and durability in heavy-duty commercial vehicle applications.
