I own a 1997 Mercury Grand Marquis LS and I've been getting a generic check engine light code p0141 meaning bank 1 sensor 2 O2 heater circuit I replaced the stock one which was old by the way with an ntk 22500 and the code cleared when I cleared it with my code reader only to return short while later then I got a an idea from someone on YouTube to wire a resistor in between the two heater circuit wires in the oxygen sensor and that didn't work either any ideas to fix this heater circuit so I can get rid of this cel thank you for any answers or ideas they would be appreciated

I’d inspect the harness for any nicks, burns, or separation on that wire. If it doesn’t have continuity, all the tricks in the world won’t work unfortunately.
