Service engine code re 'idle air control valve'.
Mechanic says I should replace.
Does this vehicle have one?
Googling it I get different responses?

What is the actual code and I can get you the diagram to try and confirm this? It may not need to be replaced. It may just need to be cleaned.

You do not have a separate IAC like most vehicles however all vehicles do have an idle control system. It just appears yours is part of the throttle body. I would suggest cleaning the throttle body and retesting.

Send me the code if this does not work and we can figure out what the issue could be. Thanks
