Evaporative Emission Control System
Canister And Purge Valve Testing
PURPOSE
Stores fuel vapor until purge operation occurs.
LOCATION
On the R.H. fender apron in engine compartment.
OPERATION

the canister, "flushes" (purges) the canister of fuel vapors. The vapors flow into the engine and are burned in the combustion process.
