Crankshaft Position Sensor
FUNCTIONS WITHIN THE SYSTEM
The ECM judges the engine speed based on the crankshaft position signal that is input into it.
INDIVIDUAL FUNCTION WITHIN THE SYSTEM
The ECM inputs the voltage change caused by the change in magnetic field generated close to the crankshaft position sensor as signal voltage.
INDIVIDUAL OPERATION
Crankshaft position sensor consists of a permanent magnet and Hall IC. When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. Due to the changing magnetic field, the voltage from the sensor changes.
Component Location
Crankshaft position sensor (POS) is installed on the transmission housing.
