Tagliani has been available since standing down from his ride with Bryan Herta Autosport prior to Mid-Ohio.
"As a driver you never want an opportunity like this to come under these circumstances, but I'm up for the challenge and looking forward to working with my friend Scott [Dixon] and the whole Target team," said Tagliani.
Dixon goes into Fontana with a 25-point lead over championship rival Helio Castroneves.
Team boss Chip Ganassi said that Tagliani's experience made the Canadian a logical choice to support Dixon's title bid.
