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.

1. Get your money back
2. DRBIII

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

SOURCE: P0340 code. I Changed cam sensor and checked

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

Car starts and runs but in reverse starts shaking SES lights up and blinks. Have changed the plugs but are getting a P0340. It's an 1998 Saturn 112,000 miles. What could it be?


DTC P0340 will set if the PCM voltage on cylinder #4 signal wire is not pulled to ground (cam signal pulse) when:
Diagnostic Aids
Important: A cam pulse missing may not affect engine operation.
?€¢
An open or high resistance on the #1 plug wire or plug will result in DTC P0340 setting.


?€¢
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 !

Neon Code P0344


I believe that the splice for the cam sensor is about 8 inches back in the harness. Power to the cam supplies several sensors. I have fixed a few that the splice was bad, There is very little room to work in to get to the splice, but it's not impossible to fix.

04 dodge neon showing P0325 and P0340 codes at same time.


Code 0325 is for a Knock sensor. Code 0340 is for the Cam sensor #1 if this is an engine with 2 heads and it is an indication of a single sensor on single head engines.

So if you do have a multiple hed engine, you may have removed the good sensor and left the bad sensor in the other head.

Remember to wipe the computer memory after installing new parts.

P0340 is for camshaft position sensor circuit malfunction so the problem can be in you hav already changed sensor, then you need to check wiring from sensor to ecu and if the wires are ok than check the ecu! It can be either of them cousing the problem.

P0340 check engine light


A fault code P0340 on the '05 Dodge Neon means, "No CAM signal at PCM." So the camshaft position sensor or its wiring is at fault.

The car will start and run without the cam signal, but it will run in "limp-home" mode and batch-fire fuel injection - So it'll run, just not very well...

First step, make sure the sensor is actually plugged in. It's on the driver's side of the head, looks like a square with a raised circle. Also check the wiring from it back to the computer and make sure it isn't shorting out somewhere. Replacing the sensor only takes those 4 bolts and a few rags for oil.

I'm not sure on the price of the part, but I don't think it's anymore than $50 or so.

I hope this helps and good luck! :)

Make sure battery has a full charge. Have a helper crank it, while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse.
