it should be located near the radiator, check for clogs find the hot compressor line and trace it to find it :) they can be hidden in many places but its usally locaed near the radiator as thats where all the air flow and exchange happens hope this helps

a small evap leak is often interpreted as a loose gas cap , which it can be , it means the evap systems integrity has been breached , it can be an electrical solenoid , switch or just a vacuum line in the system . a bidirectional scanner can run the evap test after checking the gas cap , most well equipped shops can hook up a smoke machine to the evap system service port and run the smoke test , it there is a leak you will see the smoke , makes the diagnosis quickly . get an estimate from a reputable shop , by the way this problem has no effect on drivability , but should be fixed . cheers

Below are the possible causes for your engine light and error code:
The fuel cap is probably the most common cause of this problem. It's considered part of the emission system and if faulty or not place on the filler tube correctly, it will throw an error. Best of luck with your engine light issue. Take care!

P0456: Evaporative Emission System Leak Detected (small leak)
Using a Multimeter, check the Evaporative Emission (EVAP) Canister Purge Regulator Valve N80 terminals 1 and 2 for resistance. You should get 22.0 to 30.0 Ohms. If not, replace the canister. If you do, you have other problems.
