Any of you have double check the readings for the front O2 sensor with both the OBD-2 scan tool from Alex pepper and a digital voltmeter?
i get a difference of something like 0.150 volts
(scan tool gives me the lowest reading)When i release the gas pedal at high RPM the scan tool gives me a reading of almost zero (normal) but my DVOM (fluke) gives me a reading around 0.150v
I'm beginning to think my Fluke isn't at it's best shape....

Using the OBD-2 software I get readings from 0.095 to 1.5V I even occasionally get NEGATIVE voltage. I'm assuming the overvoltage and negative voltage is due to the Turbo/unichip, so maybe I'm not the best one to ask.
99% of the time, it varies from 0.1 to .98V
