Camshaft Position Sensor: Description and Operation
-
The camshaft position sensor is located on the left-hand camshaft support to detect the combustion cylinder at any one moment.
-
It is designed so that the ECM accurately reads the number of pulses which occur when protrusions provided on the back of the left hand
camshaft-drive sprocket cross the sensor. Internal construction and the basic operating principle of the camshaft position sensor are similar to those
of the crankshaft position sensor. A total of seven protrusions (one each at two locations, two at one location and three at one location) are
arranged in four equal parts of the sprocket, as shown.
