What is this next to my TPS?

[DoOver]

Replacing my TPS as preventative (keeping the old one as trail spare). It’s a pain to get too because of my compressor. What is this pictured next to it going into the fuel rail? Is it a preventative item?

Idle air control motor. Never hurts to clean it if you're right there.
