Default Code 41 Primary O2 Sensor heater CIRCUIT malfunction!

Hey

The first thing i did was swap O2's with one that i think works from a fellow honda-techer. I still have the code though, so i am thinking that maybe it is the wiring that has a short or is not connected. So I am wondering if anyone knows what is on the same circuit as the Primary 02 sensor?? Or should i just buy a brand new O2 sensor and try that?

thanks

Not sure but do you happen to have a swapped CX/VX? And did you convert the 5-wire to 4-wire? Thats why mine threw the code

You don't need a 5 wire, but the cx came wired with a 1 wire so you would need to have wired up the 4 wire or else the ecu won't recognize it.

If your wiring is good and the O2 is good, I would assume the driver (QM3) in your ECU is bad.

well i get the same code w/ a chipped p28 and a p13. The O2 was used though, do you think a fellow HTer scammed me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I just want to make sure the O2 is all that is on that circuit before i start replacing stuff.

thanks
