I started getting a check engine light caused by a P0401 code "EGR Flow Insufficient". I replaced the EGR valve. That didn't help. I replaced the sensor. That didn't help either. Just for grins, I replaced the PCV valve. Now, I get 2 codes, the original P0401 code and also a P0402 code "EGR flow excessive". What gives? Does anybody have any idea how to fix this problem? I clear the codes and within a few hours of driving, the light comes back on. I'm having no noticeable problems otherwise. Thanks for any comments.
