He can sense chakra and whatnot, but that's a general Shinobi skill, like how Sasuke and friends sensed Kyuubi chakra despite not being sensors (noted by Orochimaru).

@BrainBrand, So? Minato can still sense the build up of chakra, see the eyes opening, and react accordingly. Besides, Kakashi noticed Tsukuyomi because he noticed the pattern of the SHaringan before Itachi fully opened his eyes. If Kakashi manages that, then Minato can. And we know Minato knows about the general abilities of Uchiha and how you shouldn't look em in the eyes lol
