Engine speed is used to:
^
Indicate the engine operating point in conjunction with the engine load. The operating point indicates the values to be used in matrices and tables.
^
Regulate the idling speed.
The crankshaft angle is used to calculate when angle-related functions should be activated, such as ignition, injection and knock detection.
Diagnostics

If the crankshaft position sensor is defective during starter motor cranking, diagnostic trouble code P0337 will be generated.
^
If the control module loses track of the crankshaft position while the engine is running, diagnostic trouble code P0336 will be generated.
