P2405 ?

[Laxcoach]

Any one had to deal with this code and issue? I found it as:
Evaporative Emission System Leak Detection Pump Sense Circuit Low

I also have the dreaded U0100 code and when starting the truck I get the "Preform Service"

Any help would be appreciated.

More details needed.
What truck exactly, how many miles, etc., etc.

Fixed the perform service or just turned the message off?
That is the reminder to replace the CCV filter, so the proper fix would be to replace the filter and then turn off the reminder.
The P2405 has me stumped, never heard of that code on a RAM Cummins truck.
On the U0100, are you sure that is correct? Or maybe U010C?
U010C is lost comm with the VGT actuator module, so you may have an actuator going bad.
Clear the codes and see if the come back.
Or get it to a good independent shop for diagnosis.

Planing to replace the CCV, just cleared the service message for now.
~Miles are 160k, not 115k too many trucks to keep track of.

Cleared the codes several times, the U0100 (lost communications) comes back every time.

P2405 also returns each time. I have not seen or had this code until the U0100 came up.

Thoughts? Anyone?
