Bad voltage regulator. Replace it. Should be built in the altenator. Or just replace the altenator. Make sure you're battery is disconnected first. Also connect battery back up after you mount new altenator. Note not knowing year of van some older cars have a external voltage regulater. Which means it will be mounted someware on the firewall or inner fenderwall not in the altenator. Make sure you disconnect battery before working on any electrical. This is importent on voltage regulaters. Because they require to be pollerized. Also check battery high voltage will cook a battery.It over charges it.

P0113-INTAKE AIR TEMPERATURE SENSOR HIGH When Monitored: With the ignition on. Battery voltage greater than 10 volts. Set Condition: The Intake Air Temperature (IAT) sensor voltage at the PCM is greater than 4.98 volts.
By doing this the engine has a high ratio of working but, the transmission also has a high possibilty of not working so, my thoughts are to just change the engine not the transmission.

Replace heater motor resistor.
According to my chart, IAT circuit high.
It could be your fan shroud or radiator hose rubbing on the fan.
ask this to the dumb mind of the dodge creator.
Code 24 throttle position sensor voltage low or throttle position sensor voltage high.
The radiator fan is probably not working.
Trouble code P0073 means:Ambient air temperature sensor circuit high input
