FUEL SYSTEM

WATER SENSOR

INSPECTION

E254D4A2

FUNCTION AND OPERATION PRINCIPLE

Water Sensor is installed on bottom end of fuel filter and
detects presence of water in fuel. When the water level
reaches the lower level of the upper electrode, the "WA-
TER" lamp in cluster should flash. If the water level de-
creases below the lower electrode, the lamp should turn
off.

NOTE

Without presence of water, the lamp should flash for
2 seconds and turn off afterward in order that this
system has normal condition.

FUNCTION AND OPERATION PRINCIPLE

Variable Geometry Turbo-charger (VGT) is used to charge
additional air into combustion chamber for improvement of
combustion efficiency.
ECM controls the VGT with controlling duty of the VGT
control solenoid valve according to engine load.
