2001 Ford Expedition XLT 4.6L MIL Lamp on
Hey Ford techs. We need help with this repeat code P0401. We first replaced the DPFE sensor as they are very common. Code returned, we replaced the EGR valve. Code returned. Made sure pipe was clear and we had airflow thu it, both good. No exhaust leaks found....
