on a 95 rear o2, does the body of the sensor need to be grounded? bc my new exhaust system does not have the ground strap ne more. ive been getting this reaccuring code rear o2 malf with a brand new sensor but i wonder if the sensor itself needs to be grounded?

My grounding strap was broken off when I replaced my cat back with a stromung, and I never had that problem. I would try tracing the wires, and see if maybe it has gotten to close to the exhaust system and fried, or shorted.
