What would happen if I walk in to court with an arrest warrant

Location: Mesa az I have an active arrest warrant for Failure to appear. I was in a park past park hours and got a citation for it, i forgot i was supposed to show up to court for it and got the warrant. If i show up to court for the citation, will i be arrested?

What should i do? I can't get a job with this warrant and I don't have $500 to pay bond I'm willing to do whatever they ask, but i seriously don't want to be arrested for something so minor
