Question about Cars & Trucks
Usually dodge--Chrysler--Plymouth, the computer has to see both the cam and crank sensor signals or it won't ground the asd relay. The asd relay supplies voltage to several systems, dark green wire with orange tracer, primary voltage to ignition coil and fuel injectors just to name a couple. There could be other issues, like a problem with wiring circuits, somewhere or voltage.
The p0522 is oil pressure sender, low voltage. The other code does relate to cam sensor. Before I replace a sensor, I try to check wiring circuits.

My thought is to get a refund from the shop that tried to replace parts in order to secure your problem. The job of the shop is to diagnose the problem, not to replace items that may be the problem. Chrysler Master Techs are not trained to just replace parts, they fix the problem by diagnosing it properly.
You need to see a Chrysler dealership so they can attach a DRBIII and tell you exactly what is at stake.
I hope this helps you. I would be mad as heck.
I would not think the plugs and wires would be the problem because they would all have to fail at the same time to provide the symptom you experienced.

SOURCE: cam position sensor broke
ok easy fix. this is common on ALL ford w this style cam sensor,3.0 eats them for lunch. the sensor base has bushings like a real distributor, they get wore and fail. you can get new from ford, or reman at auto parts about 100 bucks. they come w the sensor installed but as with either, you need the allginment tool, looks like a little hockey puck, that only come from ford to set up or check engine light wont shut off. it will run without this but poorly. if you need more advice just post a comment to this and ill do my best to advise you

A code P0340 could mean one or more of the following has happened:
•a wire or connector in the circuit could be grounded/shorted/broken
•the camshaft position sensor may have failed
•the PCM may have failed
•there exists an open circuit
•the crankshaft position sensor may have failed
With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
•Visually inspect all the wiring and connectors in the circuit
•Check for continuity in the circuit wiring
•Check the operation (voltage) of the camshaft position sensor
•Replace the camshaft position sensor as required
•Check the crankshaft position circuit as well
•Replace circuit wiring and/or connectors as required
•Diagnose/replace the PCM as required

Inspect the EIS towers and plug the wire connections for corrosion or other signs of poor retention at connections.
The electronic ignition (EI) module supplies a signal to the PCM whenever it determines that the #4 cylinder fired on its compression stroke. Because of opposite coil tower polarity, the simultaneous fir of #1 and #4 cylinders are of opposite polarity as well. Under most conditions, except decel, the waste spark cylinder fires before the compression cylinder in sequence. The EI module can determine this polarity sequence and voltage amplitude by using capacitive pickup plates located under the 1/4 coil. If the module senses a positive to negative sequence and high negative spike when #4 is on TDC, it pulls the PCM cam signal to ground signaling that #4 has just fired on compression. This signal along with the double pulse received from the CKP sensor, synchronizes spark and fuel timing.
Beside plugs , plug wires need to be replaced as well !
