hey guys,

does anyone have a log of cold start showing voltage for primary and secondary O2 for both banks that you would be willing to share?

Im chasing "P0492 - insufficient flow secondary air system bank 2" and am hoping to compare O2s from cold start through secondary air pump shutting off with a known working system vs what I'm seeing.

I know this issue is caused by a diverter valve leak pretty often, but both of mine tested ok; that said, I'm thinking to replace them anyway just to be safe since there is no record that they have ever been done by the previous owner.

Thanks for any help
