The crankshaft position sensor mounts to the engine block near the starter.

The PCM uses the Crankshaft Position sensor to calculate the following:

Engine RPM
TDC number 1 and 4
Ignition coil synchronization
Injector synchronization
Camshaft-to-crankshaft misalignment (Timing belt skipped 1 tooth or more diagnostic trouble code).
