I have a 96 Chrysler Concorde w/3.3L engine. The code says cam position sensor circuit malfunction, but it is not the cam sensor. Where can I look for the problem?

P1391 Chrysler - CMP or CKP Signal Intermittent Condition http://engine-codes.com/p1391_chrysler.html#ixzz3dGwWFAtB
Your other codes are all detailed here:

P0355 Ignition Coil Primary Secondary Circuit Malfunction

In the OB=2 codes system p0715 refers to the turbine shaft speed (TSS) sensor --circuit malfunction===causes --wiring --TSS--ECM/TCM (TCM is the transmission control module). It all refers to the turbine shaft in the torque converter

p0340 cam shaft position sensor malfunction,P0700 Transmission Control System Malfunction, P0703 Torque Converter/Brake Switch B Circuit Malfunction,
P1652 P 1 6 5 2 OBD-II Diagnostic Powertrain (P) Trouble Code For Engine Fuel And Air Metering O2 Sensor Heater Circuit Malfunction Turbocharger Boost Sensor A Circuit Low Crankshaft Position Sensor A Circuit Low Input

is it the sensor or sensor circuit if circuit need to check wiring and connections --and the other 3 codes did you correct them or just cleared all codes when sensor was replaced

P0340: Camshaft Position Sensor A - Bank 1 Circuit Malfunction

- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Faulty Camshaft Position Sensor
- Faulty starter motor
- Starting system circuit
- Dead (Weak) battery

P0340 OBD-II Trouble Code
Technical Description
Camshaft Position Sensor Circuit Malfunction

What does that mean? This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.

Symptoms
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

Also, the cams/crank are out of alignment, thats why you are getting a cam position code (P0340). For more details about your model, you can visit autozone.com (free register)

Hope helped whit this (remember rated this help) Good luck.

I RECOMMEND REPLACING THE OUTPUT SPEED SENSOR..ABOUT 40 BUCKS..WILL CAUSE THESE OTHER FAULT CODES AS WELL

Change your Crankshaft position sensor, or your camshaft position sensor. Same thing happened on my car about 3 months ago.

P0302-cylinder #2 misfire detected
P0420- catalyst efficiency below threshold bank 1
P0340-No cam signal at PCM.
The Cam sensor most likely needs to be replaced first. Clear the codes after that and drive and see what comes back on.
