    Is this an upstream or downstream oxygen sensor?

    The same DENSO Auto Parts 234-4239 is listed for upstream, downstream, upstream left, upstream right and downstream left positions, depending on the vehicle.

    How many wires does this heated narrow-band oxygen sensor have?

    DENSO Auto Parts 234-4239 has four wires and a male connector, with a 17.48 in wiring harness. Its threaded mount has a 0.708 in thread diameter.

    Can I test an oxygen sensor like this myself?

    A reliable test reads the sensor signal with the engine running, so a shop should do it. With the engine off and cool, you can look over the wiring and connector for damage.
