1. CrankAngle sensor

(Fig. 224)

The crank angle sensor is fitted on the Clutch

Housing. The crank sensor is a magnetic field

sensitive transducer and generates a voltage

output proportional to the rate of change of the

magnetic field near a "Missing tooth"

configuration. It monitors the rotating speed

(rpm), the position of crankshaft/ piston and speed

fluctuations of the engine and gives continuous

feed back to the ECU. In other words it gives

engine speed and piston position signal to the

ECU. The sensor gap should be 1±0.5mm&should

be measured using feeler gauge. If the gap

between the flywheel and crank angle sensor is

not correct, the engine will not start.

2. VehicleSpeedSensor

(Fig. 225)

This sensor is located on the Transfer case / Gear

box based on the application which gives vehicle

speed information to theECU. It also helps theECU

in determining in which gear the vehicle is driving

and ensures smooth driving at all gears.

Note

In case of 4 x 4 Vehicles the VSS is located on transfer

case.

3. Camsensor

(Fig.226)

The cam sensor is fitted on the bearing frame. The

camsensor is amagnetic 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 (90ºBTDC). 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.
