PO614 After Tire Size

[Jpeshelman84]

2008 Chrysler 300c
Was fine until I changed tire size
Now throwing a P0614 code
Tried re-flashing, taking it back to stock and everything I can find on here.

Anyone ever find a fix for this?

for some reason using scanner's special functions feature to change gear ratios or tires size can cause all sorts of issues with our mopars

dunno if the issue is in the bcm or why it creates the problems but i know it does

for the older cars like yours sometimes the tire size can be restored using a old holley hand held and the code/cel will go away

you have a trinity or predator laying around?

I tried that also and for my case it did not work, I turned off the code for now but I would like just to fix it right. Never had a problem until I decided to mess with the tire size to make my Speedo perfect.

does or did the car have a tazer in it?
