What is the function of the Camshaft Position (CMP) sensor in the operation of the Engine Control Module (ECM) on BMW M3?

The Camshaft Position (CMP) sensor is vital for the Engine Control Module (ECM) to operate fuel injection, ignition timing, and knock control. Mounted on the cylinder head, it uses a camshaft marker to generate an electrical pulse, helping the ECM identify when cylinder No. 1 is at Top Dead Center (TDC). This information is used to create an ignition spark and activate the fuel injector. If the CMP sensor fails, ignition and fuel injection cease. Testing involves checking resistance between terminals with a digital ohmmeter. Removal and installation vary by engine type, but typically involve disconnecting the sensor lead, removing necessary components, and installing the new sensor with correct torque.
