Hi, a P1684 is "Battery Disconnected Within Last 50 Starts". I wouldn't worry about that too much.

The P0340 is "Camshaft Position Sensor Circuit Malfunction". I'd definitely look into that code. I found a great article specific to the p0340 code - http://www.obd-codes.com/p0340 - it should give you an idea on what to look for, test, replace, etc. Good luck!

SOURCE: I have fault codes P1684 & P0340 on my 2002

P1684 The battery has been disconnected within the last 50 starts.

P0340


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

My 2002 pt cruiser died while I was driving first the oil light came on then it just died! I just had the oil changed 3 days prior to it dying some of the codes I received were 0340 1684 1685...


P0340 is cam position sensor. P1685 is for the key(has a chip in it) P1684 is battery has been disconnected. If the engine will still crank then codes P1684 & P1685 are probably old codes. So if the car will still crank, lets forget about those codes and focus on P0340 A bad cam position sensor will cause the engine to die and not allow it to start back up. Replace the cam position sensor and clear the code and the car should start up.

What are these codes? P1391 and P0340?


http://www.obd-codes.com/p0340

P1391 Intermittent Loss of CMP or CKP

check your cam position sensor or its connection and wiring

The crank position sensor or its wiring may be suspect as well.

P1391 c0de 2002 dodge ram van no start


Code P1391 Loss of crank or cam sensors,P0340 No cam signal at the pcm. I would replace the crank sensor first. Your cam sensor is part of the dist. on 5.2/5.9 engines.
Hope that helps.

The code P1684 is real easy. The computer is stating that the battery has been disconnected within the last 50 starts.
