Specs At A Glance

Good To Know

Q: How do I know if my vent solenoid has failed? A: A failed vent solenoid commonly sets an EVAP-related trouble code and may make the fuel tank hard to fill. A scan tool test of the vent circuit confirms the fault before replacement.

Q: Does this valve need any programming after installation? A: No programming is required on most applications since the valve is a mechanical and electrical replacement part. Clear the stored code after installing and run an EVAP readiness cycle to verify the repair.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
