Vaccum codes p2419 p2402 p2401 p043f p043e

Ok so my taco has been throwing these codes every few weeks. I reset them and they come back. Truck is still under warranty but I am concerned about the stealership telling me it could be related to my mods. Currently have the LCE header and a flowmaster 50. Everything I research says to have the evap canister replaced.

Do you guys think the codes could be related? How should I approach this with the dealer?

 

Any word on this?

 

They said it's the charcoal filter for the vacuum pump and they're keeping it till the end of the month to repair the differential as it was leaking (recall). Got a loaner from enterprise free of charge till then. So far so good! No one mentioned the mods and neither did I

 

Sounds good.. Update us when you get it back.. I'm wanting to put the LCE header on, just haven't pulled the trigger..
