FUNCTION AND OPERATION PRICIPLE

Purge Control Solenoid Valve (PCSV) is installed on the
surge tank and controls the passage between the canister
and the intake manifold. It is a solenoid valve and is open
when the PCM grounds the valve control line. When the
passage is open (PCSV ON), fuel vapors stored in the
canister is transferred to the intake manifold.

FUNCTION AND OPERATION PRICIPLE

Variable Intake manifold Solenoid (VIS) valves are in-
stalled on surge tank (VIS Valve #1) and intake manifold

(VIS Valve #2). These VIS valve #1 and #2 control vac-
uum modulators which activate valves in surge tank and
intake manifold. These valves are opened or closed by
PCM according to engine condition (Refer to below table).
