Usually, Nissan's official Nissan dealers at the GTP pump are changing the pump at the pump. The site is expensive enough, so it makes sense to try repair it (especially if the car is no longer under warranty).
You can purchase a GTP harness pump (code 49591-6C925) and find a good station to repair. You can do this yourself if you have the necessary tools to disassemble the pump. The main thing is to diagnose and make sure that one of the sappers (all of them on a Nissan Teana pump) runs before the purchase of the belt.
