possible cause for a p0430 code reading?

Question

can a loose nut and a missing nut on the rear exhaust manifold be a possible cause for a p0430
For a Hyundai Santa Fe 2005

Answer 1

Hi there,

This code is for the bank 2 converter. This is located in the front of the engine, closest to the radiator.

It is possible an intake manifold gasket leak, faulty rear O2 sensor or a poorly running engine could cause this code, however the most common issue is the converter itself.
