oxygen sensor S70 1998

You have 2 O2 sensors, one before the CAT and one after. You want a front O2 sensor, part #9202719. Search the web for a cheap one.

Most parts stores will loan out a 7/8" socket to remove the O2 sensor. Using PBBlaster helps, but let it soak a while. I thought I was going to rip off the down pipe trying to get mine off.

Yes, it is on the down pipe. The connector is on top of the transmission housing, close to the ABS module (driver's side). There are two connectors, front and rear.

Keeping it running is better than buying new
