Service Light 700 1990

Another case of an O2 sensor going bad in an 1990 Volvo 760 Turbo. I'm at the 225,000 mile mark.

    Service Light 700 1990

    Too lazy to check the 90 info, but me thinks it's the same, if so, there's a lil blue button on the back of the instrument cluster that needs pressed.

    if I'm not mistaken on the year, then all ya gotta do is yank the 2 lil covers @ either side of bottom of cluster, yank 2 screws & ya got it.

    the "service" light goes on every so many miles; it has nothing to do with the O2 sensor; that would be the "check engine" light.
