Exactly what I did with the Ultra Gauge (btw great investment at $90 shipped). Bank 1 sensor 1 shows voltage but it is not fluctuating. I'm not an expert when it comes to this but that would tell me it is plugged in getting power but not reading how it should (pre cat should have fluctuating values where as the post cat should remain constant if the cats are operating correctly)
