I have a 2. 7 sebring touring 2005, i replaced the engine with a 2. 7 2003 sebring and now i am having trouble starting the car. . delayed start, revolutions limited to 2250rpm's, trouble code 0344, replaced camsensor, checked wiring 5. 0 volts, good ground. flex plates were different between engines, also knock sensor replaced both.

Was it starting and running OK before the engine change?

OK, this probably doesn't matter, but why was the original engine removed; did it have a bad bearing or something?

the heads were warped, engine overheated. . it was cheaper to change the engine. . . the car worked fine before that.

First thoughts-
are you sure this engine (electronics) 03 is compatable with 2005?

are there any other codes other than p0344?-

you got the code- wondering do you have a scanner?

code is for intermittant- move shake harness while checking ground and 5v referance. Can't think of an easy way to ck signal wire to pcm other than scanner

Different flex-plates is a big flag to me, those are often the same over many years and engine types. If the flex-plates are different, I wonder if there are other engine differences; going along with what kev2 said about the electronics...

not sure if they are compatable if anyone has this info it would be nice to know. if so would changing the pcm solve this

Notice the differences in the values for cam signal voltage. The 2003 cam trouble codes chart states 3volts difference than the 2005 code. The codes are different also. p0340 for 2003 and p0344 for the 2005. I think there is an incompatibility with the two PCM's. My question is whether the the harness and pin locations are the same for both years. This needs to be checked out for sure. I added two PDF's for both years ad codes. You will see the differences for yourself. Notice circuit K6 for 2005 and K7 for 2003 are the cam signal circuits. Doesn't look good for the wiring and PCM pin locations. Might need a harness and PCM from a 2003 car. Might be expensive.

Coryp, you replaced the cam sensor, which year did you use? If it was a 2003 you might get away with replacing it with a 2005 to match the car. It depends on whether the two engines have the same trigger wheel and mechanical mounting for the sensor. Keep in mind, this might not be the only sensor or actuator that is different...

Unfortunately, I have to express the fact that the wirig for this engine differnce in year is quite different, so here I will expose the reasons why you need to change the wiring and the PCM. Look at the two different wiring diagrams for both cam sensor voltage supply 8 and 5 volt. In the the 2003 wiring to the cam sensor, the 8 volt supply is alone. In the 2005 cam sensor supply, the 5 volt is shared with the TPS and MAP. When seeing this, you must come to only one conclusion. These two electrical systems are vastly different from one year to the other. In 2003, the MAP still have 5 volt supply but the pin that the 2005 uses for cam K6 is used for the MAP. Therefore to amount of swapping sensors will do if you don't a complete wiring and PCM and sensor swap.

to reply to the cam sensors i used the one that was in the engine first the 2003 model. then the 1 from the 2005. then replaced with a cam sensor from napa. the new one had the same part number for both years. i also noted that the map sensor had shared the same voltage and wiring as the cam sensor which leads me to think i must try a 2003 pcm and wiring. hopefully i can do this. id like to thank you guys for your info and time helping me through this.
