BOOST PRESSURE SENSOR
(BPS)
INSPECTION
E497534D
FUNCTION AND OPERATION PRINCIPLE
Boost pressure sensor (BPS) is installed on surge tank to
measure the absolute intake manifold pressure. BPS input
voltage is changed in proportion with absolute pressure
in manifold. This information is used to control Variable
Geometery Turbocharger (VGT) by ECM.

INTAKE AIR TEMPERATURE
SENSOR (IATS)
INSPECTION
E826298B
FUNCTION AND OPERATION PRINCIPLE
Intake Air Temperature Sensor (IATS) uses a Negative
Temperature Characteristics (NTC) thermistor and senses
intake air temperature. Two intake air temperature sensors
are installed in this engine.
IATS #1 in Mass Air Flow Sensor (MAFS) and IATS #2
in Boost Pressure Sensor (BPS) are located in front of
and behind turbo-charger respectively. IATS #1 senses
air temperature entering turbo-charger and the other
(IATS #2) does air temperature coming out from the
turbo-charger.
Comparing these air temperature values from both sen-
sors, more accurate sensing of intake air temperature is
possible. ECM uses these air temperature signals to per-
form EGR control correction and fuel injection quantity cor-
rection.
