Y58/1 

Purge control valve

from activated charcoal canister

to intake manifold

The purge control valve (Y58/1) is actuated by the ME control unit by means of a PWM signal (ground side) in line with the operating condition of the
engine.
If purging is actuated, the passage from the activated charcoal canister (a) to the intake manifold (b) is opened and closed.
The voltage supply to the purge control valve is performed by terminal 87.
