Camshaft position sensor location and replacement?

Got a p0340 & p1400 code. Timing belt is fine, car stumbles time to time. 3.0 ltr v6, where the heck is the cam sonsor? Nobody lists one. Is it part of the distributor assembly? Also, is manifold differential pres. Sensor a fancy word for a map sensor?

A customer dropped off a 2001 Dodge Stratus With a 2.7L (Vin Code "U"). The engine was replaced by a shade tree mechanic. The engine they used was out of a 1999 Dodge Intrepid also with a 2.7L (Vin Code "R"). Their complaint was the vehicle only ran off spray. After having replaced the computer and reprogramming, replacing cranks sensor, cam sensor, flex plate and inspecting wiring we still have the same issue. All parts are mopar! We can unplug the camshaft position sensor and the vehicle will run (extremly rough) but only to 3,000 rpm's. Dealer says there is no difference in sensors between the two engines. Any insight as to what could be causing this would be much appreciated. As I have said before, we have used all factory parts on this vehicle. All Coil drivers are firing, The MODIS Shows we loose cam/crank signal as soon as we gain it.

I appreciate your insight. Unfortunatly those are all areas we have already checked. Since posting this I have found the problem to be the "tone wheel" on left intake cam to be incorrect for our application.

Were is the camshaft senor located
