How do I replace the crankshaft position sensor?

Anyone have a good write up or a .pdf from StarTek?

I am doing this this weekend.

Many thanks-

I did the CPS. See my other message for the full writeup. Similar title.

I read another post here tonight about not replacing sensors too quickly as the cause of a problem may be something related like vacuum line or something.

I have a situation where the key of my 98 ML320 stays in the ON position and car just cranks. I can turn it off and try to restart and luckily to date it is restarting. The MB advisor says it's something between a "timing sensor" and the CPS, as these talk to each other.

My question is, how do you diagnose these types of problems so you know what to replace? I'm a fairly new DIY'er and realize that the techs have training etc - and in this particular case what does this cranking symptom sound like to you - CPS for sure?

Been there, done that.....................sounds like a failing CPS to me. Since this failure leaves no codes and is a common failure I would replace it before you get stranded somewhere. My 2 cents.
