Chrysler Repair: 2004 Sebring 2.4 DOHC cam shaft sensor, cam shaft, failure code

Question
QUESTION: 2004 Sebring, 2.4 DOHC 88K miles. First issue in over 4 years with the car.  Initial symptom, check engine light came on after car warmed up to full temp.  Sporadically, at 2500 RPM the engine starts to miss.  Speed is not limited, and does not seem to trigger the issue.  Just can not rev above 2500 when the issue kicks in.  As a precaution, I replaced the timing belt, which was the original (figured better safe than sorry).  After about a hour of running the issue returned.  Rev above 2500 caused bad misfire.  OBDC code says there is a ckt failure in the camshaft pos sensor A bank 1.  Since then I have not been able to duplicate the 2500 RPM misfire, however replacing the sensor did not clear the code from the OBDC.

ANSWER: Hi Carl,
Was the original code erased when the sensor was replaced. If not, just disconnect the battery for a minute and then see if it returns. What was the code number? The title you gave does not jibe with the nominal 0340 or 0344 code for that sensor in that 'A bank 1' is not part of it. That sounds more like the title for an oxygen sensor. In any case, the wiring for the sensor may be the issue rather than the sensor itself. The three wires (black/light blue, violet/white, tan/yellow) are routed to pins 27,29,34 of the pcm's no. 2 plug which is gray in color. Try shaking the harness gently to see if that induces the code to be reset. Otherwise, wait it out to see if the performance issue re-surfaces.

QUESTION: Replacing the sensor did in fact correct the problem, but I still have that failure code in the ODBC.  Using the scan tool to clear codes allowed the check engine light to turn off, but the code P0340 still remains.  Is this supposed to clear after so many starts or hours of run time?  Or do I need to do something else to clear it?  Should I be looking for something further?

Answer
Hi Carl,
As far as I know, the scan tool or just disconnecting the battery should clear (but the latter approach will set a 1684 which itself will go away after 50 or so on-off cycles, it says the battery power was disconnected recently). Once you clear the codes, if it comes back then it still thinks there is problem and the things, other than the sensor it the wiring of the circuit, could be an intermittent crank sensor signal or a problem in the pcm itself about the cam circuit or the 5 volt sensor supply, or inspect the tone wheel/pulse ring.
