I made a DIY video when I replaced my o2 sensor in my 1995 993 I hope my video helps someone who wants to do the replacement themselves or for those who are curious what the steps are for the replacement even if they decide to have a shop do it.
I would have put this post in the DIY 993 section but that section says it's closed to new posts.

Thank you. These are always very useful to both DIY people and also mechanics who work on these cars.

PS: How did you find out the O2 sensor was bad and what symptoms did it give?

Well done video.
That was one of my first DIY jobs on my car and your video reminds me of what a pain in the butt it was. Easy DIY need to move a bunch of stuff to get that long length of wire where it needs to go.
If for whatever reason I need to do it again I'll definitely reference your instructions.

Just as an fyi, if you can solder, the generic Bosch O2 sensors can be used for substantially less money and time. Just match the colors when wiring. Bosch pn 15738

thanks. A check engine light came on while it was the Porsche dealer when I was getting the oil changed and the service manager said it was the o2 sensor. No other symptoms. So after looking up the replacement steps I decided to do the replacement myself.

Thanks the hardest part for me was figuring out how to get the black plastic cover off where the o2 sensor wire coupler in the engine bay is located. That and figuring out i should push up from the bottom on the rubber grommet holding the wire in the metal hole.

thanks. That is helpful info. I thought about going that route to save a lot of time and money but I wanted to replace the entire wire and o2 sensor since it looks like it was the original from 1995. It would have been nice if Porsche put a wire coupler near the o2 sensor to make the replacement easier.

I took a look at the generic Bosch pn 1573 online and was wondering wouldn't it be easier to just cut the wires near the o2 sensor and solder the new sensor to the existing wires and then seal the wires up with some waterproof shrink rubber or something? I wonder if that would work? If it would then that would make the replacement job take about 30 minutes VS 3 hours?

That's exactly how it's done. Use waterproof heat shrink and simply match the colors. Make sure to replace the heat protection tubing while you're in there.

Good to know. I might try that the next time I need to replace it! Thanks!
