30-4110 not displaying af ratio.

My gauge does not read correctly. Removed o2 sensor from vehicle. With the o2 sensor not plugged in gauge reads 14.7. If I plug the o2 sensor in but not installed the gauge goes to full lean then flashes 3 bars. Spray a rag with brake clean and wrap the sensor, it does the same thing. Seems to be a lot of problems with these gauges and sensors. Purchased June 27,2019 so it should be under warranty still.
