Canister Purge Solenoid: Description and Operation
Computer Command Control - Port Fuel Injection
The canister purge system on this vehicle has a normally closed solenoid to control canister purge. The ECM operates the canister purge solenoid which
controls the vacuum to the purge valve in the canister. Under cold engine or idle conditions the canister purge is turned "OFF" by the ECM which
blocks fuel vapors from being purged from the canister.
