fault code on golf mk4 1.6 BCB engine

[vw754]

car sounds like its running on 3 cylinders, fault code is 17591 02 linear senser........anyone point me in the right direction........do i replace the oxygen sensor? If it was a coil pack would that show up as a different fault?

IF IT WAS COIL PACK IT WOULD COME UP WITH MISSFIRE FAULT ON THE CYLINDER IT WAS MISSFIRING ON
you can check the sensors for operation using advanced measuring
