An independent assessment determined his delivery method contained a technical flaw, the International Cricket Council confirmed.
Dananjaya was reported for a suspect bowling action during the first Test between Sri Lanka and New Zealand, which took place from August 14 to 18 in Galle, with Kane Williamson also flagged.
The Sri Lanka spinner had produced a first-innings five-wicket haul in his team's six-wicket win.
Dananjaya, who was suspended late last year after his bowling action was reported against England, subsequently faced an independent assessment on August 29.
This assessment revealed his illegal action and, given the prior suspension, he was automatically suspended from bowling in the international game for a year.
Dananjaya will be able to approach the ICC for re-assessment following this period, the world governing body said.
