This system cutsandcontrols theport vacuum
applied tothe EVAP canister purgecontrol sole-

This cut-and-control operationisaccomplished
through theECM. When theECM detects anyof
the following conditions, currentflowsthrough
the solenoid valveinthe EVAP canister purge
control solenoid valvecontrol vacuum line. This
causes theport vacuum tobe discharged
into theatmosphere sothat theEVAP canister
purge lineremains closed.

• Engine stopped
• Vehicle speed:below10km/h (6MPH)

DESCRIPTION
The EVAP canister purgecontrol solenoid valveresponds to
signals fromtheECM. When theECM sends anON (ground)
signal, thecoil inthe solenoid valveisenergized. Aplunger will
then move tocut the vacuum signal(fromtheintake manifc,ld
to the EVAP canister purgecontrol solenoid valve).
When theECM sends anOFF signal, thevacuum signalpasses
through thesolenoid valve.Thesignal thenreaches theEVAP
canister purgecontrol solenoid valve.
