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.

Maybe it's a wiring problem. Have you checked the wires for continuity back to the ECU? Connector pin fit can cause problems too.

Thank you very much for the reply.


Should I check all of the wires [part of the main harness] for continuity? I already checked the wires for the O2 sensor for continuity, but neither had any. To my understanding they wren't supposed to either.

Thanks
