crank sensor is the sensor for the computer telling you you are turning the key so the engine will start. If its broken your car will not start, if it is going your car will start sometimes. Get a new one usually under 200$

The crank angle sensor is a basic component of the E.C.C.S. It monitors engine speed and piston position, and sends signals to the E.C.U. to control fuel injection, ignition timing and other functions.The crank angle sensor has a rotor plate and a wave-forming circuit. The rotor plate has 360 slits for 10 signal and 6 slits for 1200signal. Light Emitting Diodes (L.E.D.) and photo diodes are built in the wave-forming circuit.When the rotor plate passes between the L.E.D. and the photo diode, the slits in the rotor plate continually cut the light being transmitted to the photo diode from the L.E.D. This generates rough-shaped pulses which are converted into on-off pulses by the wave-forming circuit, which are sent to the E.C.U.

The sensor in Acura and Honda cars monitors crank shaft position (position of pistons and rotation of engine) the ecu uses this signal to determine when the fuel and ignition systems should work . Several other sensors are also required, but you asked about the crank.Honda/Acura sensors work off magnetic pulses from a ring with either several slots or fins in close proximity to the sensor.
