Is it possible the PCM has been swapped for an ATX PCM?

Seriously people, this is 2019 not 1920.

Certain parameters/features can go bad, and the car run just fine. Some things matter, and others are more of an annoyance with the CEL.

My Grandmother's Plymouth Caravelle had the relay driver for the cooling fan go bad in it's PCM, but other than getting too hot, the car ran perfect. Thankfully it was still under warranty...

Have you tried unhooking the battery, turning on the headlights turning them off and reconnecting the battery to reset the PCM? (Key off when doing this.)

Yes, it is to discharge any voltage left in the capacitors that may keep the PCM from making a clean reset. Some use the brake pedal, but IMHO, it is easier to reach in the window and turn the switch than getting into the car to push the brakes.
