Umm, unless things changed my 97 front sensor is for the Puter and the single wire rear sensor is for the dash.
OP:
Does your PCM read 10AFR or do you have a stand alone AFR sensor reading 10?
That code is the pcm telling you there is something with the pre cat sensor or it’s wiring. Which makes sense based on what you’re describing.
Do a once over on your wiring and if nothing is frayed or melted I’d replace the pre cat O2 sensor.
