The dealer is going to recommend replacing the sensor. Most folks here would say replace both sensors while you are having the job done.

Easy enough DIY with 1/4" drive tools.

Beginning in 2000 and for the next couple of years, the original crankshaft position sensors were of very poor quality and were quite prone to failure. Cadillac has redesigned this part twice since then. From what I hear, the latest design is quite reliable.

It's a good idea to replace both of them at the same time because, for some reason, the codes don't always indicate correctly which one is bad. It isn't a tough job to do except (on the Deville, at least) the clearances are so tight you need a skinny arm and lots of patience to get the job done.

I couldn't find a picture but I can tell you they are located on the front face of the engine, about dead center. One is just above the half-case seal, the other is just below it.

Hope that helps.
