I have 3 flashes when I check for codes. No pauses and it repeats 3 flashes only.i have a shop manual but it does not list code like all the other manuals I have.
SOURCE: Check engine code 1407
two people told me it was the egr valve
one guy said he replce the hose and it worked for him
I hope this helps
Barring any vacuum leaks, P0401 is indicative of a bad EGR valve. Hope this answers your question. Best of luck.

its the tube going from the egr valve to your exhaust it have carbon build up and you either have to replace it or get a metal coat hanger and clean it out.

332 = EGR valve opening not detected.
You should be able to find a list of DTC's on the Internets somewhere.
