After procrastinating long enough that I now can't recall where I got the part from, finally took the T5 to the indy to install the front 02 sensor. Wrong part, connector woouldn't fit. He put the old one back in, and the code is gone, & no "check engine" light.
MOral: next time treat all codes as dirty connectors until proven otherwise.
Meantime, if anybody knows what vehicle this sensor, Volvo part number 9125583 goes on, I can make somebody a good deal on one.

    Checking around the net, part # 9125583 turns out to be the front sensor for NON-turbo 1998-2000 S/V 70. Anybody interested, holler.

    Thanks for the warning.
    If your mechanic "cleaned" the O2 sensor or its housing, that may be all it needed. Most just need to be cleaned, along with the connector.
    Too many people spend too much money, just because they believe what they see on the scanner. DTCs are a good place to start the diagnosing process, not the end of trouble shooting. Eg: if you get multiple misfires, one of the codes says the cat converter is bad, not true but that code will not go away after the misfires are cured. The car's computers are not logical, it is up to the owner to use a bit of common sense.
    That is what the Brickboard is all about. Getting second opinions never hurt.
