Circuit Operation
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
The crankshaft position sensor power is supplied from the MFI relay (terminal 4) to the crankshaft position sensor (terminal 3). The crankshaft position sensor (terminal 1) is grounded by the PCM (terminal 16). The PCM (terminal 45) supplies 5 volts to the crankshaft position sensor output (terminal 2). The crankshaft position sensor detects the crank angle (position) of each cylinder, and converts that data to pulse signals that are sent to the PCM.
