All, my wife was driving our 2014 Range Rover Sport the other day and the amber check engine light came on. I plugged in my Innova Scan Tool and P2275 - O2 Sensor Signal Stuck Rich - Bank 1 Sensor 3 came up. At first I thought it was a loose gas cap so I twisted it till the clicks then cleared the code. Today, she had the truck out again and the light came on again. Scanned it and the same code popped. Should I replace the O2 sensor. Where is this one located?
