My 2014 Ram battery went dead out of the blue. I put in a new battery but a check engine light came on after the replacement was installed. Code P1DF3. Is it related to the battery going dead? The battery was about 4 years old.

Get the code erased and see if it comes back. If it comes back further diagnostics will be needed,

https://www.engine-codes.com/p1df3.html. Have you tried driving it too see if the light goes out as the ECM cycles?

I cleared the code after the code didn`t go out on it`s own. I will drive more today and see if it comes back. Thanks.
