Camshaft Position Sensor
The camshaft position sensor (1) is mounted near
the camshaft gear and the sensor functions in the same
way as the crankshaft position sensor.
This sensor detects the extra teeth (two teeth) of the
camshaft pulsar gear (2) and the engine ECU uses the
signal to calculate the piston position.

This figure shows the pulse chart of the crankshaft
position sensor output signal and camshaft position
sensor output signal.
The camshaft pulsar gear rotates once when the
crankshaft pulsar gear rotates twice (12.6 rad (720 °)
crank angle).
There is a gearless section in the crankshaft pulsar
gear. The ECU determines whether it is TDC if the
camshaft position sensor signal is detected while the
crankshaft position sensor is passing this gearless
section.
