Eccentric shaft position sensor

• The sensor pulse wheel has 30 teeth and 3 areas with no teeth.

• The angle between two notches is 10°, and the angle between two notches where there are no teeth is 30°.

• Sends the change in the amount of magnetic flux density detected at the magnet pickup coil in the eccentric shaft position sensor to the PCM as a voltage value.

• When the eccentric shaft position sensor is removed, installed, or replaced, magnetic flux of the magnet pickup coil will be disturbed, if magnetic material such as iron powder adheres to the sensor, resulting in abnormal sensor output, which may adversely affect the engine control.
