Question

It has one by the radiator, one by the fire wall and one by the middle of the car

Answer 1

P0430 Catalysts system below threshold bank 2

The location for this is at bank 2, As a rule of thumb bank 2 is where number 2 cylinder is at (except Ford product) The one in the middle may even not be a catalytic but a intermiediate muffler,
