Description And Operation: Description
Installed on the intercooler assembly, the Boost Pressure Sensor (BPS) measures the pressure of the compressed air in turbocharger.
The BPS consists of a piezo-electric element and a hybrid IC amplifying the element output signal. The element is a silicon diaphragm type adapting pressure sensitive variable resistor effect of semi-conductor. Because it is 100% vacuum and the turbocharger pressure applies to each side of the sensor, this sensor can output analog signal by using the silicon variation proportional to pressure change.
