That is not an option in Cali. He'll get an automatic fail when they hook up the OBDII computer to his car...
Did you actually clean the EGR valve or tubes before you replaced the DPFE sensor or did you just replace it and move on? If it keeps coming on after a few months you're probably getting carbon build up in the EGR tube that until it's cleaned out, will keep throwing the code. Being that you are in cali you will have a car with A.I.R. Tubes. These are aluminum tubes connected to the exhuast manifold on each side of the car. Each tube is connected facing the front of the car.
Pull them off and I bet you have a boat load of carbon build up on them. Clean them out and then that should get rid of your problem. I had a 2000 V6 and that was the problem I had.

EGR Valve replaced & getting new P0401 Code
I hate going to a repair shop and getting the run around when it is assumed I know nothing (which I admit I don't) but I like to find out
Thank You
