WARNING: This page is about a different car, the 2012 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
The Crankshaft Position (CKP) sensor (2) is located at the rear of the engine below the crankshaft. The sensor detects the crankshaft position through a (hall effect) by means of missing segments on the tone wheel behind flex plate. The powertrain Control Module (PCM) detects TDC position of cylinder 1 by means of the signal supplied by the sensor. Injection timing is synchronized by means of the camshaft signal and the crankshaft signal. This sensor is used to detect engine speed.
