whats people, hope all are well. 2010 Sport Trac Ltd 4.6L 4wd I am throwing 2 codes: P0054 & P0060 HO2S Heater Resistance Bank 1 Sensor 2 & HO2S Heater Resistance Bank 2 Sensor 2. Fuse is good. Just going to change both sensors since I have 78K miles and am going on a long drive next week (7 hrs). Any info on where they are and how hard they are to get to? I assume I have 4 of them and these are both of the down stream sensors.
