3.4.17. Boost pressure and 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 and temperature sensor
z The engine oil and temperature sensor
detects pressure and temperature and
sends them to the ECU.
3.4.19. Engine coolant temperature sensor
z The engine coolant temperature
sensor detects the engine coolant.
