Default i tested my o2 sensor and got this.....

i tested the signal side of the o2 sensor with engine at operating temp my multimeter read .045 V (45mV), on the computer side of the sensor i get .580 V (580mV). Is there suppose to be .580mV on the computer side of the signal wire??? i know that 45mv is too low from the sensor side cause its suppose to fluctuate from .200V to .800V.

any thoughts on this ????
