I should mention that I decided to replace the front oxygen sensor I removed the for repair, which requires the alternator be removed, and the AC condenser for flushing, which requires the radiator fan be removed. The engine had about 62,000 miles and ten years on it so it was time for oxygen sensor replacement. The AC compressor does not need to be removed to replace the oxygen sensor, but the space to work in is very limited. With the AC compressor removed there is plenty of room to work in. It is probably not worth the trouble of dealing with the AC refrigerant and compressor just to change the oxygen sensor. However, if you have the AC compressor and the radiator fan out of the car it is an ideal time to change the front oxygen sensor.
