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.

Repair procedures
Disassembly
In case of removing the high pressure fuel pump, high pressure fuel pipe,
delivery pipe, and injector, there may be injury caused by leakage of the
high pressure fuel. So don’t do any repair work right after engine stops.
•
Use fender covers to avoid damaging painted surfaces.
