I have been consistently getting a DT error on my 2019S with the Rex cutting out for the past few weeks. I noticed 1,2 and 3 misfire and a Lambda sensor code. Tried fuel additive and FP relay. No luck.

Looked at the codes again tonight and saw 28 total all over the place. My 12V battery is about two years old now. If terminals are tight I’m guessing it’s time to replace again.
I read someone mention to look for moisture dripping on module or cable.
Please let me know if anyone has more advice. Thank you.
