Canister Purge Control Valve: Description and Operation
EVAPORATIVE EMISSION (EVAP) CANISTER PURGE VALVE
Typical 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
EVAP canister purge valve controls the flow of vapors by way of a solenoid, eliminating the need for an electronic vacuum regulator and vacuum
diaphragm. The PCM outputs a signal between 0 mA and 1,000 mA to control the EVAP canister purge valve.
