Villager V6-181 3.0L SOHC VIN 1 EFI (1997)
Canister Purge Solenoid: Description and Operation
EGR/EVAP Control Solenoid
The Exhaust Gas Recirculation/Evaporative Emission (EGR/EVAP) control solenoid is controlled by the Powertrain Control Module (PCM). The
EGR/EVAP control solenoid controls vacuum to both the EGR valve and to the EVAP canister. When the EGR/EVAP control solenoid is off (12V
signal from the PCM) vacuum is supplied to both the EGR valve and to the EVAP canister. When the EGR/EVAP control solenoid is on (ground
supplied by PCM) vacuum is vented to the atmosphere keeping the EGR valve closed and no vacuum to the EVAP canister. The PCM will command the
EGR/EVAP control solenoid on at:
-
Engine starting condition
-
Low engine coolant temperature condition
-
Excessively high engine coolant temperature condition
-
Engine idling condition
-
High engine speed condition
-
Mass Air Flow (MAF) sensor failure
