It is really not a big deal. The sensor is located in the front of the engine and easily accessible from underneath. This summer I changed the first one on one of my friends truck in under 20 minutes as I had to figure out what to do, the second one I did in the parking lot of the airport in under five minutes in the dark. Ford initially sold the sensor for $200. I called to get some to fix the intermittent issues my friends were having as I have an account at Ford and they were only $20 a piece. I was told the price was lowered about two weeks earlier with no notice or explanation. I assume it was preemptive since lots of people were having this problem. Funny thing is all the parts houses were still selling them for $175-225.
