02' stratus 2.7v6
I'm trying to help out my son-in-law who is in the Navy & half way across the country, who is letting his mother drive his 02' stratus with ~127K, because her car, the tranny is out & she cant afford to rebuild it. I'm not familiar with dodges at all. & yes money is tight for all involved.
ANYHOW....the stratus has come up with a p0340 code twice now in as many weeks...seems to run fairly well otherwise, but apparently has very resently had a hard start & a bit of hesitation on a cold start...once driven, starts normally. it does seem to run a bit cool according to the temp gauge on the dash, & does not want to shift into OD.
resent work includes; a new upper radiator hose housing with temp sensor and battery. pretty sure it was bled/burped, meaning no air pocket.
the alternator output checked out @ 15v on cold start.
some indicate that the cam position sensor (p0340), and the crankshaft position sensor should be changed together , Is that really necessary??? or is it just a bad connection??
where is the cam & crankshaft position sensor located (no manual) & how difficult are they to change and or check?? Any special tools needed?
Is there more than 1 cam position sensor?? seeing as it is a DOHC?
Would the new T stat help cure the not shifting into OD?? My thought here is with the low temp reading...it "thinks" it still is in warm up mode and not shifting into OD?? need feed back here.

YouTube - Replacing a Camshaft position sensor on a 2002 Chrysler Sebring Maybe watch this.
However sometimes a CPS code cam indicate problems with play in the valve timing mechanism, not sure in your case.
The cold start problem sounds like an Engine Coolant Temperature sensor problem but you say it has a new one fitted.
The transmission should have its own temperature sensor, independant of the ECT sensor. In any case it would not, I think, prevent it from shifting in to OD. Low temp of the trans should just prevent converter lockup.
If it is a bad solenoid or sensor it should throw a code, otherwise it may be an internal problem.
I wish I could help more but don`t know those cars well enough.

....yeah not sure about the temp thing either...I know my wifes Milan won't drop into OD if too cold, or not up to temp,,,same for the f150...so I was presuming ( yes that gets me into trouble), the same for this dodge. Prolly end up changing the T stat and see if it helps...it drive fine otherwise

new symptoms
well did and oil change and everything looked normal there ...but a day or so later it puked the coolant on the ground as they stopped to park it. To my understanding it was not running hot.
SO I'm hoping that the T stat just stuck shut...hoping and praying.

They're electric...and they are working ...at least when the A/C is on. Gotta make sure they're working without A/C
