Can someone tell me where to look for the O2 sensor on an 89 B230FT?

    On my 87 760t the O2 sensor is located on the underside of the exhaust downpipe. I believe it is visible through a mount thing that holds the exhaust heat gather-er around the pipe, you'll have to get under the car to see it. I tried to remove all the parts associated with the intake air pre-heat system and couldnt because the O2 sensor wire went through one of the pieces. HTH.

      On my '90 740 B230FT it is on the underneath of the exhaust downpipe, and can be felt with my hand from above the car. Put your hand underneath the exhaust pipe near the Turbo, and start moving it rearward: you'll feel it and its wire.

      I just replaced mine, using an off-set crow's foot tool that attaches to a 3/8" ratchet. the tool was about $10 at Pep Boys. I was able to do the work from above. Spray first with plenty of PB Blaster.
