Condition
Check engine light illuminated.
Difficult to fill with fuel or when filling, the pump continuously shuts off before the tank is full.
When checking the vehicle for DTCs, the ECM may report one or more of the following DTCs set as current or in history: P0442, P0446, P0449 or P0455.
Cause
The EVAP canister vent solenoid (CVS) valve draws fresh air into the system through a vent.
Under certain operating conditions, dirt and dust intrusion into the EVAP CVS fresh air intake/venting system, may result in restricted air flow.
Under certain operating conditions, water, if ingested into the EVAP CVS fresh air intake/venting system, may reach the CVS valve causing corrosion in the CVS valve, and may cause restrictions in the fresh air intake path, when the valve is in the closed position.

Condition
Some customers may comment about the check engine light being illuminated.
They may also comment that their vehicle is difficult to fill with fuel or when filling, the pump continuously shuts off before the tank is full.
When checking the vehicle for DTCs, the ECM may report one or more of the following DTCs set as current or in history: P0442, P0446, P0449 or P0455.
Cause
The EVAP canister vent solenoid (CVS) valve draws fresh air into the system through a vent.
Under certain operating conditions, dirt and dust intrusion into the EVAP CVS fresh air intake/venting system, may result in restricted air flow.
Under certain operating conditions, water, if ingested into the EVAP CVS fresh air intake/venting system, may reach the CVS valve causing corrosion in the CVS valve, and may cause restrictions in the fresh air intake path, when the valve is in the closed position.
Correction (1999-2007 Classic/Old Style Models)
After following the published SI diagnostics and determining that the EVAP canister vent valve is the cause of the MIL light, replace the existing EVAP canister vent valve assembly with a new assembly. This new assembly is a sealed unit that is designed to be vented through a remote filter box. To ensure correct installation, follow the procedures below.
Important: DO NOT replace the EVAP canister assembly for this concern unless it fails the leak test.
