Re: How to disconnect knock sensor
You are so right, Gameover! I got cooled off while waiting for feedback on my question and thought that I could figure it out if I took a little time with it and , voila', I did! As you said, you simply find the "wide spot" and squeeze and pull out. It is shaped like an oval and even in brail I was able to feel it. So, thank you very much for your answer! Even though I was able to figure it out it was great to get your answer so quickly. I just finished a minute ago. Once you figure it out it isn't too tough to do.
To assist others like me I want to add that the anti knock sensor on the 93 anyway, is directly above another sensor with four wires. This sensor makes it difficult if not impossible to get to from directly below, however you can snake your arm up and around and get to it "blind". The good news is that a 7/8 inch socket fits it well and with a 6 or 8 inch extension you can get it off pretty easily - a little tight fit, but doable. Once I got the wire off it was about a ten minute job. Also, an ounce or so of oil dripped out when I removed the old one. I had some paper towels handy so there was no problem at all. Hopefully, this will help someone else out. I guess I saved an hour of labor at the shop which makes me feel really good!
Just to get a little more pertinent info in here I replaced the sensor because I got the "service engine soon" or SES light and checked codes. Got a 43 which depending on where you check says it a little differently but boils down to "knock sensor".
Thanks again, Gameover!
