Where is the crankshaft position sensor located on a Mercedes-Benz E240?

[OHannah]

The crankshaft position sensor on a Mercedes-Benz E240 is generally installed on the transmission housing, receiving signals from the flywheel's ring gear. Definition of the speed sensor: It detects engine speed, hence also known as the speed sensor; it detects the top dead center position of the pistons, thus also referred to as the top dead center sensor, including detecting the top dead center signals of each cylinder for ignition control and the first cylinder's top dead center signal for sequential fuel injection control. Working principle and function: The function of the crankshaft position sensor is to determine the position of the crankshaft, i.e., the crankshaft's angle and the engine speed. It usually works in conjunction with the camshaft position sensor to determine the basic ignition timing.
