Electrical problem
1999 Acura CL 4 cyl Two Wheel Drive Automatic 120000 miles

i have a trouble code of p0141 (heated oxygen sensor bank 1 sensor 2) that autozone told me i had when my check engine light came on. i was told this is the one that is right before the cat convert. i bought a replacement from autozone and changed it. the light with the same code still comes on. i have tried to reset the system by taking the battery off but it still comes on. can you tell me what causes this? is the sensor still bad? or what am i doing wrong? i was told there was a sensor fuse, can you tell me where that is and could that be a problem to the check engine light?

sensor 2 i belive is the one after the catalytic converter on your vehicle, a quick check for this is the first sensor is the one closest to the engine, the second one is the second one, and if you have a 4 straight you may have a 3rd one, which would be furthest from the engine.
