Setup: 99 Honda Civic ej6
Engine: d16y7, i/h/e

I'm currently getting code 41 from one of my o2 sensor plugs. Which ever sensor I plug the the "bad" plug into gets the malfunctioning code 1 or 2. I was thinking that if I got an obd-2 to obd-1 ecu conversion harness & obd-1 ecu that I would only have to run with one o2 sensor. I figure with only one o2 sensor, and one good plug I would be fine.

Anybody have any ideas about my theory?? Any tips for fixing the existing problem?? I believe it has a short in one of the black heater wires. Should I run a ground from both the wires to a 12 volt?? Any help/advice would be appreciated.

 

You can pick up another 02 sensor on here for probly 20$....

Or you can just convert to OBD1 for around 375$....

your choice

So it throws 41 if it sees either an open, short, or any connection to ground.

I've already changed them both, for way too much
