The first problem your Toyota Camry appears to have and which caused its
smog test failure has to do with the EVAP system. The trouble code indicates
there is a problem with the electronic solenoid or valve which controls the
opening and closing of the EVAP canister (Charcoal Canister) vent. Your
Toyota Camry's EVAP system is designed to store gasoline vapors from the gas
tank inside a charcoal canister until the engine is ready to burn them; at
which time a vent is opened and the fuel vapors vacuumed into the intake
manifold and combustion chambers. The problem here can be a faulty valve,
either stuck due to deposits or damaged electronically.
The second fault (Shift Solenoid) which your Toyota failed the smog check
for is transmission related. The shift solenoid may be outside the
transmission, in which case it can easily be removed and replaced, or inside
your Toyota's transmission. Although it seems the transmission has nothing
to do with emissions, the fact that it triggers a trouble code indicates it
is emissions related and can affect your Camry's emissions output.
