My 2009 Dodge Journey SXT shows code P0340 even after I replaced the Camshaft position s and the crankshaft position sensor. I also reset the codes with my code reader what else could be the issue?

SOURCE: P0340 Code Camshaft Position Sensor

The Camshaft Position (CMP) Sensor detects the position of the camshaft in order to identifiy when piston No. 1 is on its compression stroke. The CMP sensor is used for ignition timing in the Ford DIS igntion system, but not in the EDIS igntion system. Both DIS/EDIS use the CMP signal for synchronizing the firing of sequential fuel injectors.

On the 3.0L vulcan engine, the CMP signal is generated by a single Hall-Effect magnetic switch, activated by a single "vane" spinning around by virture of a synchronized shaft which is driven by the camshaft. 

The CMP sensor & synchronizer/shaft are located behind the intake manifold (i.e., back near the firewall on a Ranger) on the top of the cylinder block. If you just need to replace the sensor, it is a simple job of unplugging the electrical connector and removing the screws holding the sensor in place. Here is a sketch of the sensor to give you an idea what to look for:

P0340 Camshaft Position Sensor "A" Circuit Bank 1 or Single Sensor

P0700 Transmission Control System (MIL Request)

The code P1684 is real easy. The computer is stating that the battery has been disconnected within the last 50 starts.

Sounds like the timing belt broke. Unfortunately this vehicle was not equiped with no contact valves so if that is the case you will need to have the engine and Head rebuilt. If the crank position sensor can't sense the position of the crank it should shutdown the electrical to keep you from damaging your engine.

SOURCE: getting code P0340, No camshaft position sensor

Replace the cam sensor with a factory sensor. Aftermarket sensors can still trigger the light when nothing is wrong.

SOURCE: I got a camshaft position sensor malfunction code P0340.

it sounds like you have bigger problems if your car does not crank(turn over) then your timing belt could have broken and the one piston could be hitting a valve causing it to be locked up.normally when any sensor is bad car engine still cranks it just doesn't start.
