There is a crankshaft position sensor that measures how fast it rotates
The crankshaft position sensor bolt size isÊdependent upon the type of engine. In most cases the crankshaft position sensor 9/16.
Technically both, before the vehicle is running on its own via combustion the crankshaft rotates and moves the pistons, once combustion has occurred the pistons take over if you will and turn the crank which rotates the next piston into position for combustion
crankshaft The crankshaft rotates. A torsion bar twists.
Bolts
The engine's camshaft rotates at half the speed of the crankshaft. The crankshaft turns two full turns for every one full turn of the camshaft.
One half the speed of the crankshaft.
i am doing a coures in tafe inspect and service engines and i would like to know this rotates the crankshaft as the piston moves down the cylinder
The crankshaft position sensor measures the rotational position of the crankshaft for the engine computer. That info is required for fuel and ignition timing.The crankshaft position sensor measures the rotational position of the crankshaft for the engine computer.

the position off the crankshaft sensor
Crankshaft position sensor function is to monitor the position or rotational speed of the crankshaft. It is an electronic device and it is used in the internal combustion engine.
According to my Chilton repair manual , the crankshaft position sensor is used to determine crankshaft position and crankshaft RPM
