P1405 OBD II Code
Any Idea what this is about? We had a drastic weather change here. We've gone from the teens to almost 50 degrees in the past two days. The EXPY started fine this morning. After I came out of the store and started it, I got a service engine soon light. I came home, hooked up my tester and I got the above code. I cleared it out to see if it's weather related, started the car again and no code.
Anyone have thoughts or a theory?

What year/engine?
My guess is the upstream DPFE EGR hose is iced up, plugged, or disconnected.
(Older DPFE sensors would accumulate condensation in certain weather condictions and freeze in the DPFE. What year did you say it was?)

Well, since it takes TWO CONSECUTIVE DRIVE CYCLES in which the monitor test runs and fails to set the MIL, your "test" is not valid to see if the problem is resolved (which it probably isn't).
Just starting the engine doesn't qualify as much of anything, especially an OBDII drive cycle.

Report back it several weeks..
All tests rarely run on every trip and any given trip seldom qualifies as an OBDII drive cycle.
FWIW, you'll likely end up with a new DPFE sensor before it's all over with.
