Getting codes p0430 and p0328 on our 04 frontierr

Question

Are these codes related or seperate problems?

Answer 1

Hi there,

These are separate issues. P0430 catalytic converter below threshold on bank 2. This means the converter isn't functioning like it should.

P0328 Knock sensor.

This code is less important and usually won't effect the way the engine is running. In most cases you can clear this code without worry and it won't turn the check engine light on.
