Help! what's my code mean?

[chris712vt]

My check engine light's been on ever since I installed my new catback. This is a 95 Talon ESi by the way. Been about 2 months since I put my exhaust on, car runs just fine, the light just annoys me and I'd rather fix the problem. Check this out and let me know what you think:

My printout of the OBDII code:
Vehicle Scanned Global OBDII
DTC (Codes)
P0141
O2 Sensor Heater
Circuit Malfunction
(Bank 1 Sensor 2)

I'm pretty sure that's saying my rear O2 sensor is dead, malfunctioning, something. I started out looking for new O2 sensors to replace it with, and found a universal one my friend would sell me. I've also read about how to wire up an O2 eliminator and trick the system. But I was also informed of an O2 simulator I could buy that kind of does the same thing, but still uses the O2 sensor and so I looked into it more. Here's the link to this company's website.

The only thing keeping me from giving it a shot is that my code printout mentions a heater malfunction, and this O2 simulator doesn't affect the heater wires, so I don't know if it will help me or not. What do you think? Does this code mean something is wrong with the heater wires, a blown fuse, etc? Do you think this simulator would fix my problem, if not would wiring in a new universal O2 sensor fix it, and if that wouldn't what do I have to do to fix whatever this is?

Thanks a lot,
Chris

just replace your rear o2 sensor with an oem one from a dealership or someplace and should fix all you problems

well I can get my friend's extra O2 for 10 bucks, and it's brand new and all I've gotta do is splice it right in. But will a new sensor solve my problem? I'm not familiar with these codes, it didn't say the sensor is bad, it said the heater circuit malfunctioned. So I don't know where the problem is. And if I were to put a brand new O2 on it, wouldn't the simulator do me just as good?

pull out your driver's seat and check the wiring harness under the carpet. That's a "free" start.......

another thing,
when you installed the catback, maybe you over twisted the wires and one came loose. You can also check the continuity from the harness to the o2 sensor. I would buy that $10 o2 sensor whether you need it now or not. If your examination of the harness and wiring leads to nothing, then replace the sensor. It couldn't hurt, as long as you wire it correctly.

Thanks. I'll get the universal O2 sensor anyway then I guess. Good point about over-twisting, I may have pulled on the wires too much. I'll check that out soon and see if there's anything obviously wrong, and if I don't find anything I'll see if the new sensor fixes the problem. If that doesn't work I guess something else must be wrong elsewhere dealing with the heater wires.
