I had a cel code: P0135. I replaced the 02 sensor, erased the code and cel turn back on and gave me the same code.

Now i'm troubleshooting using Honda Service Manual. One of the test ask me to check continuity between "body ground" and terminal 3 and 4 individually of the O2 sensor.

My question is. What would be a "body ground"?

This is my first time using a multimeter. I apologize in advance for being naive.

 

bare metal on the body where there are ground wires bolted to i would assume.
someone will correct me if im wrong...

 

That's what I thought. I tested continuity between the terminal from the O2 sensor and the ground wire that is bolted to the engine.

There was no continuity so according to the service manual my O2 sensor is bad, but its new so I'm skeptical.

I gonna go to the auto store and try and trade it for another one. Thanks for the reply.

 

have you checked all the wiring that goes to the o2 sensor???
could be a short of some sort in that
but yeah definitely try another o2 sensor if you can as well

 

Correction: if there is no continuity the O2 sensor is good. My mistake.
