OBD II Codes P0340 and P0344

2005 Jeep Wrangler X - 53k- I6 - MT

My check engine light came on on the ride home from work...figured it was a loose vacuum line because my cruise control would not work. However, it would downshift very roughly.

When I got home, I turned it off and tried to start it again- nothing. Just cranking. I did the key trick and got the following codes P0340 and P0344. Looks like they are camshaft position sensor related??? Any thoughts since they appear to be the same code? 53k and I am all ready losing one??

Anything else you can tell me about these codes???

Where would you start?

Sounds like the cam position sensor (AKA "stator" & "coil pickup") took a dump. I have heard of instances where the magnet falls off the mounting plate and falls into the distriburtor.
