iii. CAMSHAFT POSITION SENSOR
The cam sensor is fitted on the cylinder head
cover. The cam sensor is a magnetic field
sensitive transducer and generates a voltage
output proportional to the rate of change of the
magnetic field near a "camshaft lobe"
configuration. The cam sensor senses the position
of the flag on the Exhaust camshaft and gives
feed back to the ECU regarding the cylinder No.1
(90ºBDC). The sensor gap should be 1±0.4mm.
If the gap is not correct and also the position of
camshafts with respect to crank shaft (set during
assembly), the engine will not start. While the
engine is running & the cam sensor fails then the
engine will continue to run till the engine will stop
& will not start again.
