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
Removal
Put on gloves to protect your hands.
•
When prying with a flat-tip screwdriver or use a prying trim
tool, wrap it with protective tape, and apply protective tape around
the related parts, to prevent damage.

Operation and Leakage Check
Check all of the following
items:
Component
Procedure
Brake Booster (A)
Check brake operation by applying the brakes during a test drive. If the
brakes do not work properly, check the brake booster. Replace the brake
booster as an assembly if it does not work properly or if there are signs
of leakage.
