I dont think their is one (crankshafts usually sit in oil-they are extremely heavy metal and rotate very fast...your rpms measure how many times the crank makes a 360degree rotation in a single minute.....)but Lucky for us.......A crankshaft does not need a sensor....if you have failure, your engine wont start.

Oh yeah, the 4-stroke cycle is completed when the crank spins a full 720degrees-180per stroke.
