    Man, THANK YOU, I was looking for this info! Do you happen to have this also for the downstream O2 sensor? Or a link to the full workshop manual where I can find that info? A link to the full manual would be great because I could use it for a few other things.

    Both sensors are in the attachment above, at least the resistance check. I'll pm you regarding the other.

    So thought I'd give an update. Worked on the o2 issues first. So pulled out the windshield wiper motor stuff and left the inverter and I could get to the o2 just fine, HOWEVER it's been replaced before and was crossthreaded and only about 2/3 way in so not seated. Couldn't get it backed out. Ended up dropping all the exhaust including manifold. Put it in a vice and the sensor just broke trying to back it out, drilled the rest, used a pick on the remaining, then had to rework the threads because they were screwed by someone cross threading it the crap out of it. I installed the new one with anti seize and then put the exhaust system back in and that fixed all my exhaust codes.

    For what it's worth I found it easier to just drop the exhaust manifold than remove all the engine junk to do it up top. Plus if there's a issue you can deal with it with the mani off. Pulling the manifold off took about 20 minutes...same putting it back on.

    Still looking into the coolant codes but they haven't come back on so maybe it was just a fluke?

    Glad things are working out for you. If you need technical information I suggest using Mitchells1DIY here.

    Do it Yourself Automobile Repair Manuals - Mitchell 1 DIY

    It is about as cheap as you are going to get for good technical information, if it helps Snap-On tool owns them.
    There is a professional version that professionals use, very expensive.
