O2 Sensor reading in ohms?

I need to find out what the (perfect)reading 'in ohms' should be on an 02 Camaro Z28 for the O2 Sensors?

Thanks in advance!

    I am going to assume that you are trying to measure the o2 heater circuit with the sensor disconnected, if you want to see the output voltage to the engine computer that's a whole different process and is done with the engine running and hot. The reading for a good o2 heater circuit should be about 20 ohms, the running voltage output should move between .2 and .8 volts for upstream and stay mostly above .5 for the post converter sensor.

    Although it varies, generally 0,8 to 1.4 ohms shows a good sensor.
