this could be the issue when you're getting the p0456 code. brittle plastic tubing that is cracked or broken. did a temporary fix on mine by wrapping electrical tape around the cracked end then plugging it back in. been fine since.
Update code came back, so I replaced the tube. Give yourself about an hour and half to do the job. Not hard to do just gotta snake the tube through some wiring.
this is the replacement part.
