Evap Control System

Circuit Description

The EVAP purge solenoid valve allows manifold vacuum to purge the canister. The Powertrain Control Module (PCM) supplies a ground to energize the EVAP purge solenoid valve (purge on ). The EVAP purge solenoid control is Pulse Width Modulated (PWM) or turned on and off...
