Circuit Description
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
An ignition voltage is supplied directly to the Evaporative Emission (EVAP) canister vent solenoid. The control module grounds the EVAP canister vent solenoid control circuit to close the solenoid by means of an internal switch called a driver. The scan tool displays the commanded state of the EVAP canister vent solenoid as ON or OFF. The control module monitors the status of the driver. If the control module detects low voltage on the control circuit when the driver is commanded OFF, this DTC sets.
The table illustrates the relationship between the ON and OFF states, and the OPEN or CLOSED states of the EVAP canister vent solenoid. See EVAP CANISTER VENT SOLENOID & CONTROL MODULE COMMAND RELATIONSHIP table.
