P0410 / p0420
Hello,
Has anyone had any experience on P0410/P0420 codes? I clear the codes, 2-3 days later they are back.
Google searches say different fixes, Some say air pump has failed, some say the check valves between air pump and manifolds stuck, Yet others say the O2 sensor. All had good reasons for their responses . Just curious if anyone on here had this happen to them and what the real issue was.
