I finally got my new 2022 RAM 6.7L in from a dealer out of state (found the exact truck I wanted), and I drive home, park the truck, cruise around, and realize that I'm getting a CEL.
Plug in the trusty code reader and get a message for a P2609 (No Voltage Drop Seen From Intake Air Heaters).
I thought it was weird, so I cycled the truck and drove it around, thinking it may be a fluke and would go away - no dice.
I feel like I'm going to tear my hair out.
Thirty miles on the truck and throwing a damn code.
The truck starts/drives fine (as you would think), but the light stays and can't be cleared.
The truck is obviously under warranty still, so I will likely take it in for them to mess with, but I am at a loss for words as to why this would be a problem with a brand-new truck off the lot.
I'm aware of the killer grid-heater bolt and thought of this (and checked the stud), but I don't think it would be a problem on a truck with such few miles/run time.
This post is mainly to vent, but any words of wisdom would be appreciated.
