SOURCE: What does code #31 for a plymouth voyager mean?
According to minimopar.knizefamily.net, fault code 31 is "Purge Canister/EGR Solenoid".

I ran into this problem this past winter and after going threw everything I finally solved this problem by taking off the fast idle servo and cleaning behind it with solvant If it gunks up in their it cannot function properly causing it to stall when idiling or coming to a stop. Try this simple solution it will more than likely work for you and keep it from stalling.
SOURCE: Transmission Input Speed Sensor Replacement 1997 Plymouth Voyager
The first thing I needed to do was to identify my transmission. The
2000 Dodge Grand Caravan Sport (3.3 L) has the A604 transmission, as
did any Caravan from 1989 to 2006. Might as well replace both sensor and will take less then 30 min from start to finish.
Vehicle's with A604 transmissions have chronic
input and output speed sensor problems and also with the little wire
connectors to those input and output speed sensors. The dealer
offers a repair kit for these wires instead of buying a whole new wire
harness. On most of these vehicles, If you have a code 41-44 you should
check for weak battery voltage first. now the shop needs to check the
wiring for poor grounds. I have seen that The transmission controller
often goes bad causing these same codes, so be careful.
Parts/Tool List:
10mm socket (to remove top of air intake)
1" socket (to remove/tighten sensors)
standard screwdriver (to loosen hose clamps)
Vehicle Speed Sensor - INPUT
Vehicle Speed Sensor - OUTPUT
Removal/Installation:
The first step is to remove the airbox cover. This can be removed with
a 10mm socket. Under the airbox cover is the actual airbox; remove the
filter by unsnapping the clamps holding the lid in place. Maybe this is
a good time to see if your filter needs to be replaced.
Once you've got the airbox cover and filter off, you should be able to
see where the sensors are located on the transmission. On the left is the input sensor behind the Transmission Solenoid pack by the transmission dip stick tube , and
on the right is the output sensor.
The input sensor is located just under two little hoses; remove the
clamps and get those houses of the way. Make sure that you keep track
of which hose goes on the left and which one goes on the right. To
remove the sensor connector, there's a tab that lifts up, probably
under the sensor. It lifts very easily, and the connector slides right
off. If it's not coming right off, you haven't properly lifted the tab.
To remove the sensor, you need a 1" socket which should fit right over
the terminal. The socket should also be large enough to clear the hose
nipples.
Note that with both of these sensors, the base is plastic. If you use
anything other than a 1" socket, you'll rip the plastic to shreds and
never be able to get the sensor off. USE the socket.
In most situation, the output sensor was covered in sludge, which may
have been the source of the problem. Both the input and output sensors
use some kind of magnetic receiving unit, and those magnets will pick
up tiny metal shavings that are suspended in the transmission fluid. I
suppose 10 years worth of buildup is enough to cause the sensor to
throw bad signals. But maybe something on the inside caused the
problem... so replacing it outright was the best decision.
Anyhow, after replacing the two sensors, the transmission problems 98% of the time will completely be resolved. No more weird cruise control issues, no
more erratic speedometer, and no more 2-to-1 gear drops when coming to
a stop. Problem solved. Good luck and merry xmass
