I have the P0336 diagnostic procedure ready to post, but due to forum problems, I have not been successful.

I cannot read through the diagnostic procedure right now, but will do so when I have a chance and comment further at that time.

*EDIT* - Have you checked the ECM 1 (15A) fuse? If the fuse is good, you should check continuity from the fuse to the pink wire at the CKP sensor. If that checks out, then you need to check continuity between the yellow wire and pin 31 (yellow wire) on the PCM C1 (blue connector) this is the 3x CKP sensor signal. Next check would be the purple wire at the CKP sensor connector to the purple wire at pin 28 on the PCM C1 (blue connector) this is sensor ground.
