Description and operation
Installed on the intercooler assembly, the Boost Pressure Sensor (BPS) measures
the pressure of compressed air in the turbocharger.
The BPS consists of a piezo-electric element and a hybrid IC amplifying the element's
output signal. The element is silicon diaphragm type and adapts pressure sensitive
variable resistor effect of semi-conductor. One side of silicon diaphragm is 100%
vacuum and turbocharger pressure is applied on the other side. Hence, output is
gained from the silicon variation in proportion to the pressure change.
