If you search around, you'll find pictures and procedures.

Stand on the driver sid fender. Use a bright light and look at the rear of the engine. It is between the engine and the firewall. You should see a cable going into it. There is nothing around that sensor.

RR requires some feel because you cannot see the torx (E8) screw holding it. You can see the cable and sensor but not the screw.

I suggest you take the connector plug off and spray some elctrical cleaner on the connector and the plug. Sometimes, corrosion in that area can increase the resistance read by the computer.
