Could someone help me figure out what to do?
My CEL came on last week. I checked it with my scanner and 3 trouble codes popped up. P0400, P0420, and P0430. The first of the three, I know, is related to the EGR system; either the EGR valve itself or the tubing within that system. However, I have never see the other two: P0420 and P0430. It says it is a problem with the catalyst for the left and right bank. What does this mean for me? What component is the culprit of this? The car drives fine and I have had no problems with it. Thanks.
