    Oxygen sensors... what brand(s) do you like/recommend?

    Well, I'm figuring that the code 91 is telling me something important there - I'll have to check connections to be sure, but I figure it's probably time to change the O2 sensors anyway. I would NOT be surprised to find I still have the factory original sensors in there.

    Eh, so I'm mostly coming across Bosch and Denso sensors... they seem to be the most commonplace. Anyone have a preference/recommendation? Are there particular brands that have better/worse reputations?

    Thanks in advance.

    Bosch would have been original equipment. I've never had a problem with using them. Most of the sensors on the car were originally made by them anyway.


    I've generally found that if you get an oxygen sensor code, then the sensor is working. If it tells you its running lean, it probably is. Or it could be something jacked up with the thermactor, causing constant air injection. That would do it too.

      Well, I've always had a thermactor code since I got the car (had the impression it wasn't able to inject air where it should), but never had the oxygen sensor code before. Can't remember, but I seem to recall it's However, fairly recently, fuel economy has dropped further, and now I'm getting the O2 code.

      Still, at 118k miles, I guess swapping the factory-issued O2 sensors couldn't hurt. Bosch it is, then. Thanks!

        The thermactor codes are somewhat reliant on the oxygen sensors. What its looking for is for the sensor to show lean when the thermactor is turned on. If its stuck in the on position, it won't go more lean, so it may give you a code. Obviously this relies on the thermactor stuff being present and operational. It might be worth pulling the rubber hose that feeds to the back of the head and capping off the line into the head to see if the oxygen sensor code goes away. If it does, you've found your real issue.

          Rubber hose? Hmm, I guess the last time I was trying to figure out the thermactor thing, I was looking at ENTIRELY the wrong tubing!

          Once I get my whole lock cylinder issue resolved, I'll have to give this a look.... HOWEVER, if I correctly, the oxygen sensor code is for the left side, and the thermactor code is for the right side.

            Totally not meaning to jack the thread, but I have a pair of Standard Motor Products O2 sensors for my Lincoln. Are they any good or should I get Bosch for the Lincoln and put the potentially shitty SMP ones in the F-150? Anyone have experience with the Standard parts?

              They should work fine. I've had no issues with Standard branded sensors... at least the ones that work out of the box.

                Its rubber hose from the smog pump through the valves. From the valves to the metal pipes, its a short piece of rubber as a connector. Those are by far the easiest ones to disconnect. Getting the metal apart without breaking it is difficult at best.
