He was elected consul in 165, together with Gnaeus Octavius. Titus is described as consul "posterior" by Livy, which means the Centuriate Assembly elected him after Octavius. However, in the Fasti Capitolini—the list of consuls made under Augustus—Titus is promoted to the first place, probably because his great-great-grandson was a member of the College of Pontiffs, which was tasked with establishing the Fasti. Around this time, the emperor Augustus was also trying to revive several distinguished patrician houses and therefore supported their enhancement in the Fasti. Titus' colleague Octavius was not a direct ancestor of Augustus, although from the same gens. Despite being a "homo novus", Octavius was already famous by the time of his election, as he had led the Roman navy during the Third Macedonian War, for which he was awarded a triumph in 167.
