You can get free owners manuals online at:
or just type "owners manuals" in your search.
Here is a post I found that worked for my 2005 caravan.
For a 2001 Dodge Caravan: The owner's manual is vague, only stating that all fuses are under the hood in the fuse box, no diagrams. Once you have removed the fusebox cover, the diagrams for what each fuse does is provided under the lid. UNCLEARLY marked is the radio fuse, a 20amp fuse located 2nd row from top to the right of the accessory relay. It is marked: RDO/IP IGN.

SOURCE: P0700, P0750 and P0755 codes
Trouble Code: P0750
A/T Low/Reverse Solenoid Circuit Failure
L/R solenoid control circuit is open or shorted to ground L/R solenoid control circuit is shorted to system power L/R Solenoid is damaged or has failed TCM or PCM has failed
Trouble Code: P0755
A/T 2/4 Solenoid Circuit Failure
2/4 Solenoid control circuit is open or shorted to ground 2/4 Solenoid control circuit is shorted to system power 2/4 Solenoid is damaged or has failed TCM or PCM has failed
Trouble Code: P0700
Automatic Transmission Control System Malfunction
The presence of this code means the TCM detected a problem TCM related Sensor has solenoid is damaged or has failed This code is for information only - check for other TCM codes TCM or PCM has failed

Map sensor bad or vacuum &/or power to it missing. Map sensor located on intake manifold or firewall. It has a vacuum hose & electrical connector attached to it. To verify it is bad disconnect electrical connector to it while running. Idle should smooth out & run good. If so need to replace.

Manifold Absolute Pressure (MAP) sensor measures the changes in the intake manifold pressure which result from engine load and speed changes, and converts this measurement into a voltage output.
A closed throttle on when the engine is decelerating would produce a relatively low MAP output, while a wide open throttle would produce a high output. Manifold absolute pressure is the opposite of what you would measure on a vacuum gage. When manifold pressure is high, vacuum is low. The MAP sensor is also used to measure barometric pressure under certain conditions, which allows the PCM to automatically adjust for different altitudes.
The PCM sends a 5 volt reference signal to the MAP sensor. As the manifold pressure changes, the electrical resistance of the sensor also changes. By monitoring the sensor output voltage, the PCM can determine the manifold pressure. A higher pressure, low vacuum (high voltage) requires more fuel, while a lower pressure, higher vacuum (low voltage) requires less fuel.
A high or low voltage fault in the MAP sensor circuit should set a DTC P0107 or DTC P0108. If the MAP sensor sends an intermittent zero voltage signal to the PCM, a DTC P0106 will set.
