Where is the crankshaft position sensor located on the Mercedes-Benz 272 engine?

[Hadley]

The crankshaft position sensor on the Mercedes-Benz 272 engine is located on the transmission clutch housing, at the rear left side of the engine block. Working principle of the crankshaft position sensor: It determines the position of the crankshaft, specifically the crankshaft's rotation angle. It typically works in conjunction with the camshaft position sensor to establish the basic ignition timing. The sensor detects engine speed, piston top dead center position, and crankshaft rotation angle - these parameters are crucial for calculating the air-fuel ratio of the mixture and regulating ignition timing. Functions of the crankshaft position sensor: Detects engine speed (hence also called the speed sensor); detects piston top dead center position (thus also known as the top dead center sensor), including detecting top dead center signals for each cylinder for ignition control and the first cylinder's top dead center signal for sequential fuel injection control.
