QuestionI have a P0601 Code; Intake control valve. Memory check malfunction> what does this mean. I went to an Advance Auto and they ran a diagnostic for me. Said they had never seen this code before. also went to Dodge dealership and they said they did not know what it was and wanted to charge me $135.00 to run the diagnostic to figure out exactly what it was. No straight answers from anyone. The car has lost a little power and it has turned off on me when I come to a full stop. Has never turned off while driving. What can this be and how can I repair it, or can I repair by myself. I am not a master mechanic but do know how to use a wrench somewhat.
Thank you.
