I very highly recommend going to an autoparts store and purchasing a "Haynes" manual for your vehicle. They are under $20 and will not only show you where it is but how to test it, rebuild it (if applicable), or replace it.
Thanks rhillstr. I probably will buy that manual but I went ahead and bought an OBD scanner which is how I knew the cam sensor was bad. I went to the autozone website and they have a good picture of the sensor and where it is, how to change it and how to test it. I plan on getting manuals for all 3 of my vehicles but I wasn't quite sure which was the best. Chiltons has very little in the way of troubleshooting but I was wondering about a MOTORS manual. Do you have any experience with them? Are they any better than Haynes?
In my experience the Motors manuals are the best available, but then again the ones I'm referring to apply to 60's and 70's cars. Much better than Chiltons or Haynes. Better schematics and such.
