O2 Sensor testing tips? 850 1995

I have no 850 experience, but am used to metering 240 O2 sensors.

There is now an 850 in the family, and I'd like to know if the sensors (two?) signal can be conveniently accessed somewhere with a DVM.

The few 850 images I've seen look like a flat 3-pin plug (2 heater, 1 signal?), unlike the handy separate signal wire on the 240s and my '93 940.

Any suggestions will be much appreciated,

    The 850 has a four wire connector for each sensor (there are two sensors). One pre-cat and one post cat. The wires are one gray (ground) one black (signal) and two white (heater). The connectors are kind of a pain to get to unless yo have long arms. Volvospeed.com/bay13 has pics.

      Thanks a lot, bl—that's just the info we were looking for. I'd forgotten about Bay13 too.
