Crankshaft Position Sensor: Description and Operation
California
DESCRIPTION
The crankshaft position sensor senses the crank angle (piston position) of each cylinder, converts it into a pulse signal and inputs it to the engine
control module, which then computes the engine speed and controls the fuel injection timing and ignition timing based on the input signal.
OPERATION
Power to the crankshaft position sensor is supplied from the MFI relay, and the ground is located in the body. A 5V voltage is applied from the
engine control module to the crankshaft position sensor output terminal, and the crankshaft position sensor generates a pulse signal as it switches
from OPEN to SHORT (power transistor inside the sensor switches ON/OFF) between the output terminal and the ground.
