I replaced my o2 sensor after putting in headers a while back, but I still had my CEL on. Pulled the code today and found that it's the heater circuit on my pre-cat o2 sensor. Anyone have any ideas how to fix this without replacing the whole sensor?

I used the OEM sensor, so it came with the harness attached. Is this a fuse issue? Harness issue? Any advice is appreciated!

Thanks!

check out the fuse, check out the connection point. it should have warranty right?

Let's hope so, I got it from acuraoemparts.com... Do you know which fuse it is?

anyone know which fuse it might be or have any other suggestions for me?

look in the fuse panels by the driver side door hinge and the same spot on the pass side. it will say "FUSES" or something like that

Thanks Rajca! I actually know where the fuse boxes are, I just didn't know if anyone happened to know which fuses I should look to replace. Some of them are obvious, but some are kind of ambiguous.

look for any that says o2sensor or heater, also look in the fuses under the hood. if i cant find what im looking for, i just take them all out one by one. takes a bit longer but that eliminates the possibility of a blown fuse
