I have a feeling the sensor is bad. I recently bought an Ultra Gauge so I could have more output then just what the gauges show. When I look at bank 1, sensor 1, the it shows no movement. Because it is precat the values should be changing. bank 2 sensor 1 does show fluctuation while b1s1 sits steady and does not move. I have a feeling the sensor is just shot (unlike my thought that it wasnt even plugged in before). I already bought the parts to fix it. Might as well at 97k.
