I have a 99 accord with a OBDI H22.

About a month ago, I received a cel 41. Because I have about 130K miles on the O2 sensor, I figured that the sensor was going bad, and that it was time to replace it.
Today, I replaced the sensor with a Honda OEM, but the code is still there, and I have also tried to disconnect the battery.

I have also measured the resistance between the black wires, and it's somewhere between 30-40 ohms. Further, there is no continuity from either wire to the ground.


Any help is much appreciated.

If you can't stand the issue anymore... Get a ecu conversion harness & a chipped ecu with o2 heater disabled

Thanks, that's a alternative.

Could I disable t with any ECU, or do I need a specific kind?

What would the ECU conversion harness do in this case.

Thanks

Maybe either of the wires on the car has continuity to ground. Offhand I don't know wire colors, but check the car's wires that match up to those 2 black wires. One should get battery voltage when the engine's running. Check the OTHER one for continuity to ground while the car's off.

It's possible that plug is fouled up? Bent pins? Dirty? Loose? Pinched under an exhaust bracket? That wire goes to the ECU; you can check for the same things at that end.

Unfortunately, chasing wiring problems can be a real tedious PITA.

Thanks for the info.

I'll try to see what I can do.

You would need a obd2b to obd1 conversion harness & a chipped ecu.

Fixing the issue at hand would be easier.

Yeah I already got that, because I have a OBDI H22 in my 99 accord.

I would like to fix the problem, but if not I might get a ECU that may over look it.

Does anybody know if Hondata or AEM EMS would, or could be set to, overlooking the primary O2 sensor?


Thanks
