94 ex coupe throwing CEL 41 (primary oxygen sensor heater)
looking at buying this 94 ex coupe. only major problem is that its throwing a code 41 (primary oxygen sensor heater). i did a search and got some info but am still kind of confused. btw this car has a cat-back exhaust (apexi i believe) and a "hi flow cat".
ok so now my question:
how many o2 sensors are there on this car? 1 or 2? i saw the one on the header. is there a way to fix this problem without buying a new o2 sensor? i read that it could be a fuse or the wire. thanks.

k thats what i thought. the b series engines and newer d series have 1 o2 before the cat and 1 after as well correct? i was mainly concerned that since the previous owner put on a "hi flow" cat that he might have made it so that an o2 sensor was completely eliminated, which obviously isnt the case.
