P0455, and nothing else
A search shows not posts since last year. What is the current thinking about the cause and cure of a P0455 (check engine light) with no other codes, and no GAS CAP message?
Thanx for all the opinions of our colleagues.

Just had this on my 06 after replacing gas cap, appears it was the vent solenoid located on passenger side frame rail forward of rear axle. You will need to take out passengers side inner wheel well to get to large hose from evap canister. Job is a PITA, but code has not return since.
