I have a 96 Accord, 4cyl, auto. Sunday, the CEL came on, had the code read and it was P0141 65 Secondary HO2S Heater Circuit Fault (Sensor 2), so I replaced the O2 sensor that the shop gave me, the one in the exhaust manifold. Pulled the radio/clock back up fuse under the hood, had it out for about 30 minutes while I did other things to reset the light. Light came on about 3 seconds after start. So I go back to read the code, same thing.
What should I start looking for? Did they give me the wrong sensor?
Any help would be appreciated, especially if it saves me some time!
Thanks

 

Secondary HO2S = behind cat converter, not on manifold

 

 

oh well, $100 down the drain. I'll tell the wife it needed it anyway
