Forward oxygen sensor sends error code V70-XC70 1999



The sensor connector is a bit hard to reach but once you see how it works, it's easy. The two connectors are mounted side by side, each on a "stand off" which often breaks off when you try to slide the connector off (no big deal). Once you have it off, there is a slide that you pull up on which releases the connector from the sensor wire harness. Sometimes, you need to pry the slider with a small screwdriver to get it started. If you do it right, there will be little to no resistance pulling them apart. Again, once you see how it works. it's easy. Check volvospeed.com/bay13 for pics.
