Hi, I drive a 2001 Mercedes E320 CDI. Can someone tell me is the Crankshaft Pulse Sensor held in place by a Torx screw. I was told they just pull out. Mine seems pretty tight. I do not want to have to drop the gearbox to get it out. I have tried doing it from under and above the engine, no joy. Ps Why do some people refer to it as a Position Sensor. I thought a Position Sensor was a completly different part. Thank-you, Brian..
