Canister Purge Control Valve: Description and Operation
ENGINE CONTROL COMPONENTS
Evaporative Emission (EVAP) Canister Purge Valve
The EVAP canister purge valve is part of the enhanced EVAP system that is controlled by the PCM. This valve controls the flow of vapors (purging)
from the EVAP canister to the intake manifold during various engine operating modes. The EVAP canister purge valve is a normally closed valve.
The EVAP canister purge valve controls the flow of vapors electronically by way of a solenoid, eliminating the need for an electronic vacuum
regulator and vacuum diaphragm. The PCM outputs a duty cycle between 0% and 100% to control the EVAP canister purge valve.
