Where is the crankshaft position sensor located? on 2001 Mercedes-Benz S600

My S600 heat up to a certain temp and shuts off, and has to sit for about 3 hours before I can start it again.

On top drivers side of transmission bell cover.

1) Pull air cleaner entirel.

2) After air cleanner removed, place MULTIPLE layers of heavy cardboard on top of engine w/ protective blankets. DO NOT FRACTURE THE SCORES OF ELECTRONICS AND CONNECTIONS ON TOP mOF ENGINE.

3)Slide over top of engine with head near hood hinge drivers side. WATCH YOUR KNEES.

4)Locate CPS with flashlight.

5) A tight fit and patience will allow R&R with a torx style socket in as little as 10 minute... and up.

6) Use an assistant to hand you things and retrieve the CPS when you drop it.

I don't know where it is but I had it replaced this week. $600.00 Now it works fine.
