Re: Knock Sensor
The knock sensor is located about half way on the lower block, back side. Are you sure you don't have an EGR problem?

Re: Knock Sensor
Would an EGR throw throw that code? I have a new ERG in the garage for my wifes 94 Le Sabre. I'll have to check to see if it's the same. I use to work at a Buick dealer and collected a few parts in the 8 years I was there.

Re: Knock Sensor
A faulty EGR (stuck open) may cause the knock sensor to detect detonation, hence the comment concerning the EGR, rather than the sensor itself. Of course, you could have a vacuum leak, or other problems as well.

Re: Knock Sensor
I haven't really had time to get to check things out till recently. I replaced all vacuum lines, pulled the EGR and bench tested it. It opens and closes when jumped. I tried to replace the knock sensor but could not get the old one out. Is there a special tool for this? I'm getting very frustrated with this car. It ran like a champ till I parked it about a year and a half ago. I would like to get it running again so I can give it to my nephew. It is to nice of a car to send to the boneyard. Any suggestions would be greatly appreciated.
