I'm not sure where it is on the 2001 CLK 430, but on the 99 clk 430 it located between the rear of the engine bay and the rear of engine on the driver's side! Black connector. You'll need a flashlight since the location is hidden from sight. I'm in the process of changing mine. You can buy the Crank Position sensor at autohaus in Arizona for $56.87.

If your 3.5 engine is the same as that in a 2001 Olds Aurora, go to www.autorepair.about.com and search on "2001 aurora 3.5 crank sensor". One of the hits will be a diagram of where the crank sensor is located (above the starter motor). Note that for this engine, a "relearn" mjust be done after replacing the sensor. There is a link to the procedure for removing/installing the sensor and for doing the "relearn". Hope this helps
