the sensor that gave me the P1193 code has NO continuity( open circuit) between the red(power) wire and the white(ground) wire.

the resistance between the yelow and black wires starts at 6ohm and slowly climbs to 18-20ohms as you leave the meter connected for a few seconds. I also tested a sensor that I "believe" to be good and it had the same resistance on the yellow / black wires(sensor circuit) as the bad one above, but had 6 ohms between the red & white wires(heater circuit)....hope this helps

 

Thanks for the additional information regarding the O2 sensor. Glad to hear you got it fixed.
