The sensor I believe you are talking about is the oxygen sensor (front) and requires a special socket to remove it due to limited space.

Check out Volvospeed.com and look for SENSORS.

Front o2 sensor does not need anything special to remove it, save for a 19mm or so open-end wrench. IPD sells a fancy tool to do it, but then again, that's their job.

I did my front o2 sensor and the hardest part is un/doing the wiring harness, believe it or not. Remember to hit the sensor with some WD-40 or equivalent because it will be really tight.

Thanks I was able to change OK. The o2 sensor was just a bit tight.
