The O2 sensor can lose from its housing. I had never done any repairs to this O2 sensor. Which it is located at position bank 1 sensor 2. The sensor connection came lose from where it is held on to the frame. It caused the wiring to get slack and wrap around the drive shaft. This happened as I was driving home from work. I started to hear a noise coming from the vehicle. As I looked underneath the SUV I seen the O2 sensor was caught on the shaft. I thought it was just a once time incident that had occurred to me. But as I went to the salvage yard to get a harness. They told me this was a common issue on these model trucks.
