Had one die on me last weekend. Air fuel readings stuck at 15.9 and not moving. Normally we swap to a new one and load the calibration (AKA moneymaker) disk to get them talking to each other again. Since this sensor had little run time on it I was going to swap O2 and ECM from my other car to rule out a wiring issue. I had the sensor swapped and was booting up the laptop to save the files before swapping ECMs. I noticed the wideband symbol was showing, so I fired it up and it was reading just fine. Did I just happen to get lucky and buy two different Fast setups about 8 years apart that are calibrated the same? I realize I shouldn't trust the accuracy, blah, blah, but I was just looking for movement where there was none before. I guess it is safe to shell out the bucks for a new sensor now. Maybe there is a relatively small number of sensor calibrations and it is not that weird to have a new one work without recalibrating it?
