Good battery is important. I had a check engine light on, and the scanner said bad cat. The vehicle, a 2016 one ton van with the original battery. I knew the battery was bad because it wasn't pushing full voltage, so sensors start to act flaky.

Instead of spending a pile of money on a new cat, I bought a decent battery. Check engine light went away, and it scanned clean.

If the battery is more than 5 years old, have it tested, especially before winter. I got 8 years out of my last battery, but had some strange sensor issues before I replaced it.
