.
ACCELERATOR PEDAL POSITION SENSOR
Accelerator pedal position sensor is integrated with accelerator
pedal, and detects accelerator opening angle. ECM uses the
output voltage of this sensor to control appropriate throttle
valve opening angle and fuel injection volume. This accelerator
pedal position sensor uses Hall IC and is a non-contact type.

EVAPORATIVE EMISSION VENTILATION
SOLENOID
The evaporative emission ventilation solenoid, an ON/OFF
type solenoid valve, is integrated in the evaporative canis
-
ter.The evaporative emission ventilation solenoid is installed
between the evaporative canister and the air-releasing end,
where the evaporative emission ventilation solenoid takes or
shuts off air.When the current is not flowing through the coil, the
air flows between the nipples, "A" and "B", and through the
evaporative canister.When the current is flowing through the
coil, the air is sealed in the nipple "A" and the air through the
evaporative canister is shut off.When monitoring the evapora
-
tive leak, the ECM turns the evaporative emission ventilation
solenoid on to create the slight vacuum condition in the evapo
-
rative emission control system. The ECM shuts off the air flow-
ing through the evaporative canister to maintain the vacuum
condition necessary for monitoring.
