Service Engine Soon :(

Hey guys i have had a service engine soon light on my 2001 v6 mustang on for a while. I took it down to auto parts store, got my codes scanned and it came up with the problem is "PO402" a EGR Valve. So she cleared the code yesterday and the light went away but unfortunately it is back again today. Scanned again and still "PO402". Does anyone know how to fix this because my ford dealers are jerks. I called wanting info about the "PO402" code and they said they cant tell me they will tell me after they hook it up to their computers for $94.95. yeaa right...

Thanks Guys,
Luke

Take it in for an oil change, and they'll do it for free. -Usually.


Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion.

This is usually caused because of carbon deposits on the plunger and it will not open and close all the way. Remove the EGR and clean the unit using carb cleaner. Try not to spray the cleaner directly on the diaphram because the cleaner could damage it.

P0401 and P0402 i believe was a recall involving the dpfe sensor replacement. i dont know what years it covers but you should check into it. preferably at the dealer

Why drive a Prius when you can have a Fiesta!!
