Canister Purge Control Valve: Description and Operation
EVAPORATIVE EMISSION (EVAP) CANISTER PURGE VALVE
EVAP Canister Purge Valve
Electronic EVAP Canister Purge Valve
NOTE: The EVAP canister purge valve may also be referred to as a vapor management valve (VMV).
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
electronic EVAP canister purge valve controls the flow of vapors electronically by way of a solenoid thereby, eliminating the need for an electronic
vacuum regulator and vacuum diaphragm. The PCM outputs a signal between 0% and 100% duty cycle to control the EVAP canister purge valve. On
applications with an electronic EVAP canister purge valve, the PCM outputs a signal between 0 mA and 1,000 mA to control the solenoid.
