Crankshaft position sensor
The crankshaft position sensor uses the signals of the pickup coil that is mounted on the right side
of the crankshaft. When the rotation of the pickup rotor that is attached to the crankshaft causes the
projections on the rotor to pass by the pickup coil, an electromotive force is generated in the coil.
The voltage of this force is then input into the ECU, which calculates the position of the crankshaft
and the speed of the engine. The ignition timing is then determined in accordance with the calcu-
lated data, in order to determine the corresponding injection timing. Based on the changes in the
time intervals of the signals generated by the pickup coil, the ECU calculates the ignition timing
advance to suit the operating conditions. The injection timing is also advanced in accordance with
the ignition timing in order to supply fuel to the engine at an optimal timing.
