any recent exhaust work?

transmission work?

recent upstream o2 sensor changes?

 

I’d check the transmission harness if this is a sudden out of the blue problem...

 

All those codes can be caused by the main wiring harness connector where it passes through the firewall.

 

Nothing was done to the vehicle no maintenance at all this happened just out of the blue
