I've done a lot of searching through the forums and haven't seen found anything on how to change out the crankshaft position sensor. Is there a how-to out there? I'm not exactly sure where it is located, so any information on how to change it out would be greatly appreciated

 

If it's the crankshaft position sensor I know. It'd be behind the timing belt in the lower part where the crank is.

You'd have to remove the timing belt last time I had to do mine.

 

Does it require you to remove the water pump in order to get in there?

 

I do not think so... I'm not sure how it is with the Lancer ES, but on the Evo, its behind the timing belt where the crank is. (I'm pretty sure its the same on the ES)
