I have a 1997 LX 3.8... and my "Service Engine Soon" light came on a few weeks ago. I didn't think anything of it, and drove with it like that for a few days. Well, after it not going off, it started to get on my nerves. So I took it to Advance a week or so ago, and had the scan for codes. They said that my "cam shaft sensor" is bad. So I purchased a new one for $30.00. When I opened my Haynes book, I couldn't find anything on replacing the camshaft senor. I say crankshaft sensor and other odd-n-ends, but nothing about the cam shaft sensor. Will someone please tell me what I need to do, to replace this part.
