by memory I believe those are for the EVAP system. There is a solenoid in the engine bay on the drivers side of the intake area. Has vacuum lines and a electrical plug. Check those for tightness. There is also a test for that solenoid.
Hopefully is it not for the rear charcoal canister which is tucked above the rear pumpkin and not easy to get to. A few malfunctions have been reported on that unit over the years.
