5 wire o2 sensor blues

[FormulaTwo]

Alright
Got a "used" 5 wire o2 sensor today for free that a friend of mine took from a running car. I was throwing a code 48 which was Lean Air fuel sensor..

Everything dealing with my o2 sensor is hard wired. Running a cx wiring harness. where i repinned at the ecu to allow for the 5 wire.
I am pretty sure that everything is wired up right or i think i would be displaying more codes than it is. I have the right ecu incase you are wondering.

So anyways, the car is no longer throwing a code 48
It has now moved on to a code 41.

From what i looked up it says that its a bad o2 sensor heater.
I am wondering a couple of things.

first of all, does this mean the new o2 sensor i installed is even worse than the old code 48 one?

second, is there anything i can do to trick the ecu, or hard wire something into the sensor itself.
i searched btw , according to svoboy : "You can run a 1k resistor from POWA to A6 to get rid of that code 41."
Is this also true for a 5 wire? and what effect will it have on gas mileage if the ecu is tricked into thinking the o2 sensor heater is working?

let me know guys

I am trying to be a cheap basterd as long as i can. $300 for an o2 sensor is ridiculous. Making this one work out for FREE would be so much better.
