I have a 2003 jeep wrangler with a check engine light on- P0456 code. Evaporator emission- small leak detected. I'm having trouble finding any leak. I'm looking for any starting points or suggestions. Jeep is running fine. Thanks in advance

You will just have to check all the EVAP vacuum lines, it may be a cracked or loose conection, these sort of leaks are a pain to locate, you just need patients

This could be referring to either the evap canister or the catalyst system, which there is one main one and two secondaries inside the exhaust down pipes according to my reference material.
