    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.

    Both at the same time is a warning bell. I would be looking at the heater circuit for faults even if you do replace the sensors or even unplugging one at a time.

    Thanks for the info guys.
    When you say check heater circuit for faults do you mean check the wire harness for damaged wires?

    Check to heater wire for voltage, also plug one in at a time and look for voltage drop. I don't know the circuit off-hand but if you get the same fault across two sensors at the same time I suspect they are parallel wired off of the same circuit. A short in one can cause an over current to be read by the ECU.

    Piece of mind - nice avatar!

    Also corrosion on the connecters if you live in road salt country.

    thanks again for the explanations. The connectors were fine, no corrosion. I just changed both of the downstream 02 sensors and cleared the code. I took the lazy route, that's what happens when you have alot to do and not enough time to do it. I will see if the check engine comes back on after some drive cycles.
