OBD2 code P1401
Does anyone know if the OBD2 Code of P1401 is going to be the same as OBD Code of P0401? If this is the case, from reading on the web site, i will assume the problem will be my DPFE Sensor. Can anyone tell me if these are in fact the same codes? By the way this web site has been a tremendous help....
Thanks!!!

Hi,
I was just researching this for a customer.

P1401 is going to be the sensor, you want the plastic one (newer style - I would go dealership) and not the metal one (Autozone).
P0401 is going to be the EGR system itself.
SEAFOAM it before replacing the sensor to clean out carbon.

I did not realize this was an old post and have no way to delete the reply - oh well.

Your conclusion about the P1401 code will be accurate almost all the time.
However, regarding the P0401 code, experience shows that the likely cause is 1) Crappy DPFE sensors, 2) clogged EGR ports, 3) everything else including the EVR solenoid and the EVR valve. Numbers 1 & 2 will account for over 95 % of all occurrances.
Seafom won't get anywhere near the EGR system, so don't bother.
