Camshaft Position Sensor

The camshaft position sensor senses the protrusion of camshaft to identify a particular cylinder. The camshaft position sensor senses the piston position.

When the crankshaft position sensor system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.

The sensor consists of a permanent magnet and Hall IC.

When 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.

ECM receives the signals as shown in the figure.

Clutch Pedal Position Switch

When the clutch pedal is depressed, the clutch pedal position switch turns ON and the clutch pedal position switch signal is sent to the ECM. The ECM judges the clutch pedal conditions via the signal (ON or OFF).

Cooling Fan

Cooling fan operates at low and high speed when the current flows in the cooling fan motor.
