I have a 2000 Honda passport 3.2 v6. The scanner said code 401 and 452, Insuficient fuel return some like that. I change the EGR and the light still on with the same codes. Can be a problem with the ECM (the computer)?

P0401 Insufficient EGR Flow

A code P0401 most likely means one or more of the following has happened
There is a blockage in the EGR (tube), most likely carbon buildup
The EGR valve is faulty
The EGR valve may not be opening due to a lack of vaccuum
