Crank sensor
Vehicle speed sensor
also controls the Inlet metering valve on the Fuel
Injection pump, Engine cooling Fans, Air
conditioning and Exhaust Gas Recirculation (EGR)
valve.
The injection parameters are corrected for various
atmospheric conditions like cold and hot climates
and different Altitudes. Corrections are also applied
considering engine safety in case of faults and any
abnormal overheating. Fault detection is made
simple. Faults are recorded in the ECU which makes
it easy to be read with the help of a diagnostic tool
and to find a solution.

Vehicle Speed Sensor:
This sensor is located inside the Gear Box which
gives vehicle speed information to the
ECU.Italso
helps the ECU in determining on which gear the
vehicle is driving and ensures smooth driving at all
gears.
EMS consists of the following sensors and
components
1.
Crank sensor:
The crank speed sensor is fitted on the clutch
housing. The position sensor is a magnetic field
sensitive transducer and generates a voltage output
proportional to the rate of change of the magnetic
field near a “sensed target” configuration. It
monitors the rotating speed (rpm) and speed
fluctuations of the engine and givens continuous
feed back to the
ECU.Inother words it gives engine
speed and TDC position signal to ECU.
