Hello everyone, I tried posting this earlier, but I guess it didn't work. I'm having a problem with my oxygen sensor. I need the bank1 sensor1, which is the passenger side first sensor. I went underneath the truck and took a picture of the existing sensor to see if I can see the item number. It appears to be the item number for the driver side sensor 1, which is bank2 sensor1. The item number from motorcraft for the passenger sensor is 8F9Z-9F472-C, which I need. And the one that's in the first bank is item number 8F9Z-9F472-B for the driver side. So my question is, should I purchase the one I need for the passenger side, or do I just buy the same one that is there now. I attached a picture of the sensor that's there now. If anyone has any experience with this issue please chime in.
