2023 Transit Connect - Hello, Could someone please help me with figuring out this issue, Today after the service tech did a scan on my vehicle due to engine light being on, it was discovered that it needs a new EGR valve. The code that came up was PO400 (1/2) stored be help would be greatly appreciated. I just need to know s a if I can slap a Band-Aid on it and I just need to know if it is I am hoping that there is some type of fuel additive to minorly correct this issue.
If you need a new EGR valve or have a malfunction related to it no "bandaid" that you can "slap on" or snake oil additive is going to help.You have to find and repair the underlying problem.
