I can't give you specifics because it's a difficult problem to trouble shoot this way. What I can tell you is the error codes are not specific. For instance, P0340 will show up if there is a loose wire in the camshaft circuit sensor harness. But it doesn't discriminate between that and a bad sensor. So the camshaft sensor may or may not have been the problem. The possible causes of this code are
1) A wire or connector in the circuit could be grounded/shorted/broken,
2) A failed PCM,(power control module),
3) An open circuit,
4) A failed crankshaft position sensor.
Your going to have to inspect the wire for any problems. If you can, check all the wires for continuity. A good idea is to pull all the relevant plugs and cote them with some die-electric spray.
If you still have the same issue you may need to replace the crankshaft position sensor. Or possibly the PCM unit.
Sorry I can be more helpful.
Good luck.

On that model,it could be the timing chain has jumped,or broke.If this is so,you need a mechanic to replace the timing chain,it is a deep job.Take the cam shaft sensor back off.Look in at the cam,and have someone crank the engine over and over,and see if the cam is turning.If the cam is turning,this will tell you the timing chain is not broke.But it does not tell you if the chain has jumped.Lining the crank at top dead center,and looking at the cam reluctor will.The cam reluctor will line up with the cam sensor pretty much perfect.If this checks out,then make sure the reluctor has not come loose or is missing.If I can help let me know.

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.

This could be related to a loose camshaft drive belt. If you have slack in the belt the camshaft will rebound on over run causing the P0340. It can also be a Crackshaft sensor problem too.(P0335) Hope this helps...
