3.4.16. Accelerator pedal sensor
z The accelerator pedal sensor transmitted the driver’s acceleration input to the
ECU.
z A voltage is generated across the potentiometer in the accelerator-pedal sensor
as a function of the accelerator-pedal setting. Using a programmed characteristic
curve, the pedal's position is then calculated from this voltage.
3.4.17. Boost pressure & temperature sensor
z The boost pressure & temperature
sensor are connected to the intake
manifold by the O-ring and
measures the intake manifold's
absolute pressure and temperature.
z The output signal is inputted to the
ECU where, with the help of a
programmed characteristic curve, it
is used for calculating the boost
pressure.
3.4.18. Engine oil pressure & temperature sensor
z The engine oil pressure and oil
temperature sensor measure in the
engine lube oil and measuring data
is inputted into ECU.
3.4.19. Engine coolant temperature sensor
z The engine coolant temperature
sensor measure in the engine
coolant circuit and measuring data
is inputted into ECU.
