1999 Ford Expedition Eddie Bauer 5.4L MIL Lamp on
Posted to Ford Driveability on 5/23/2003 18 Replies

Hi guys, I have this car that had P0401 – P0402 Codes so I replaced the EGR valve and now after 3 days later same code again. Does any one know where to go next? Is the EGR sensor next? Any help, Tips would be appreciated. Thank you.
