I had this same type of problem on my 2000 caravan about 8 years ago. A friend of mine was a transmission mechanic for chrysler for years and had me unplug the sensor on the trans. that he said was for smog related signal and it has ran fine ever since. I want to say if I remember right it was located on the front side of the trans. near the back of the block. IT'S been a while though. If I get a chance to crawl under in the next few days I will send you an update.

Ignore the previous advice as it is nonsense.

Of those 3 codes, only the first one has anything to do with the operation of the vehicle. The second 2 are EVAP emission codes. The P1698 indicates that the PCM is losing communication with the TCM which probably means the TCM is going bad but could be a wiring issue also.
