Need Answer Quick Please

My wifes 01 4.6L Expedition thru the p-0401 code the other day and I have replaced the egr valve and cleaned the tb and all egr passages. I think its the DPFE sensor since its still throwing the code. Question is will it be ok to drive until I can get the sensor on Monday. We are leaving tonite on a 500 mile drive and I dont want to break down with the kids.

Usually a P0401 won't cause any problems other than maybe a bit of a surge at cruise speed. It should be ok to drive.

Probably a vacuum leak. It shouldn't give you any major issues as long as you don't mind looking at the CEL the whole trip.
