P0300 and P0339; Crankshaft position sensor?

Got some misfiring and DTC throws P0300 and P0339. Anyone have this problem in the past? I'm assuming a new CPS is in order since P0339 is something about an intermittent CPS? Anyone know where this is located? Thanks in advance.

I installed a Billet catch can about 2 weeks ago and a new EGR valve about 3 weeks ago. I seriously doubt it's related but any thoughts on any connection?

Ok, found the cps in the service manual. It's on page 8i-19. Is that (right next to)/underneath the alternator? Looks simple from what I can tell. One connector and one bolt it looks like? 9 ft/lbs on the Hemi from what I can tell.

I had this Problem!

The CKP ensor is about $45 from the Dealer

Located on the botton of the block, on pass side, infront of the Starter; held on by 1 10mm bolt and obviously an electrical connector. Took me about 10 mins to fix, hardest part is getting under vehicle....

Hope this helps...

The one under the Alternator is the 4.7L

Correction: "CKP ensor" = Sensor

Gotcha... Good to know someone had the same issue and that's it's an easy fix like I thought. Thanks for the information. It wouldn't surprise me if the pictures are swapped in the SM??? I'll crawl under there and find it.

Crankshaft position sensor is RHS rear, by flywheel. Camshaft position sensor is RHS front, by alternator.

Look in Section 14 of the FSM.
