Camshaft Position Sensor Circuit Malfunction when you installed the harmonic balancer you may have damages a wire or sensor the following links will help with your p0340 code

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 !

camshaft position sensor circuit malfunction---check the connection and wiring around and to the sensor the following link can assist you with the trouble shooting
http://www.obd-codes.com/p0340 P0340 Camshaft Position Sensor Circuit Malfunction http://www.myautorepairadvice.com/p0340.html

Symptoms can include: Hard starting or no start
Rough running / misfiring Loss of engine power Causes
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

Possible Solutions 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

CAM or Camshaft Position Sensor Testing

Hi...
The Code P0340 on your Stratus is :
Camshaft Position Sensor Loss signal.
Ok, The first step is check tha condittion on the connector.
For corrosion, bent pins or damaged wires.
If you found that everything is ok.
Replace the Cam Position Sensor.
The Cam Position Sensor, Is common that the Cam fail on this Vehicle and similars of this.
Tha Cam position sensor Is located:
At end of the engine head, driver side. Is attached with 4, 10mm
screw, and the connector at the center of the sensor.

I hope this help on your problem.
Thank you for use fixya...
