CEL Code P0401 EGR Flow Insufficient

[Jim Vidmar]

I have CEL Code P0401 and keep blowing fuse #17 (20 amp) in the driver side fuse panel? Could this be the DPFE/EGR Valve Pressure Sensor?



Thanks~

replace the DPFE sensor, as for the fuse, I believe the 20 amp fuse is for the Fuel pump...

Thanks Todd! Is there a cross-reference available somewhere that can tell me what #17 is actually controlling?



Take care~

The fuse is for the cigarette lighter and the OBD port... SO check your horn, Cigarette lighter and that stuff...

Remove radio bezel and check to see if cig lighter wire came loose. Make sure it's installed. Remove lighter, put in new fuse. Try lighter and see if that blows fuse.

I had the 401 CEL code , I replaced my DPFE ($33 at NAPA) and so far so good on the code (knocking on wood)

Thanks guys! The lighter has not worked for some time, so I will check that out first!



Have a good day!
