What can cause p0328 and p0430 codes.

Question

I'm getting these codes and after reseting them they will stayed cleared for 2 to 3 days.

Answer 1

Hi there,

The P0430 is for a faulty bank 2 catalytic converter. Since the code is returning it's likely the converter itself is the problem.

The P0328 is a knock sensor code. This code doesn't turn on the light and you are only seeing it because the P0430 is turning the light on. Most often the knock sensor itself is the cause of the issue.
