Question about 2007 Toyota Corolla
Codes p 0440 through to p 0459 all refer to the EVAP system.
code p 0455 refers to EVAP system very large leak which refers to a loose or missing gas cap
manifold leaks are a small leak in the codes and many are miss- read as a vacuum leak can be from the transmission actuator hose missing , and the vent controls leaking
A lot of the EVAP codes refer to the purge valve or the purge valve solenoid

SOURCE: intake manifold gasket / replace
NOTE The 3.8L (VIN K) non-supercharged engine uses a two-piece intake manifold consisting of an upper air plenum which mounts the throttle body and a lower intake manifold assembly which houses the fuel injectors. The 3.8L (VIN 1) supercharged engine uses a similar lower intake manifold. The supercharger serves as the upper manifold.
NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold. Remove the upper intake manifold to service the lower intake.
The 3.8L (VIN 1) supercharged engine uses a manifold similar to the 3.8L (VIN K), but the supercharger serves as the upper manifold.

Upper Intake Manifold (Plenum)
NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold.

Unscrew the bolt that holds the negative connection to the Impala's
battery. Set this bolt aside for later use.
Remove the engine cover to access the intake manifold and manifold
gasket. Disconnect the throttle body inlet duct from the engine.
Twist off the radiator cap to allow draining of the coolant to flow more
smoothly. Place an empty container beneath the radiator's drain plug, and
remove this plug. Allow all of the engine coolant to drain into the empty
container. Replace the drain plug once you are finished.
Tag all of the electrical wiring and hoses before removing so that
reconnection is precise to factory settings. Remove these parts, individually,
from the intake manifold.
Loosen the bolts that hold the intake manifold to the Impala's engine
block. Lift the intake manifold from the block once all bolts have been
Use the flat-head screwdriver to pry the old intake manifold gasket from
the engine block. Discard this part once you have removed it.
Clean the engine block thoroughly with the engine degreaser and linen
cloth. If necessary, use a gasket scraper to remove excess buildup and grime.
Place the old intake manifold on top of the newly-installed manifold
gasket until it aligns with all of the holes of the cylinder flanges and
Attach all of the bolts with your hand to the manifold. Once all bolts
have been positioned, use a torque wrench and apply 15 foot-pounds of pressure
to the bolts to secure the manifold into place.
Reconnect all of the necessary hoses and electrical wiring to the
intake. Pour the engine coolant back into the radiator.
Reattach the engine cover on top of the intake manifold and engine
block. Start the Impala's engine and check for any leaks around the new intake
