Oxygen sensor bench test video. Good or bad?
I took out my oxygen sensor yesterday to give it a test I am getting really crappy gas mileage. Gave it a bench test tell me what you think I can not get the sensor past .85 on the meter.

This link says the O2 sensor range is 0.2 volts to 0.8 volts. Also interesting to note that the link says heated O2 sensors can reach 500C in 8 seconds......closed loop happens pretty quick.
