QuestionQUESTION: 1998 avalon piece broke off near egr vavle. It is in line with the egr valve and it is like a 2 inch round black plastic cylinder with black foam around it, hollow and the air seems to just flow through it, no wires, so I just connected the hose directly to the egr valve. I can't find this part and I don't know what it does, any idea?
ANSWER: This is the EGR vacuum modulator valve, contact the toyota dealer for an exact replacement.

QUESTION: Thanks, but it is not the part I am referring to. I have attached a picture, with the part circled in red. It has only 1 inlet and 1 outlet, and it doesn't show up on parts web sites. The egr vacuum modulator valve shows up in pics and it is not the part I am asking about. I look forward to hearting from you. Thanks so very much.

AnswerToyota sometimes uses a vacuum dampener it some applications, not sure why other than maybe to store a small amount of vacuum to activate the vsv faster when needed, not really important but if you show the picture to a toyota dealer parts department I'm sure they can order one for you.
