Default 4wd light stays on and p1762

Our 99 ram has the 4wd light stuck on even though it doesn't feel like it is in 4wd. This has been going on a few months (we don't drive it that often). When we were using it the other day the check engine light came on and it started shifting funny. Got the code read and it said p1762.

Where should I start? We don't have a lot of money (just had a baby in Dec and became a stay at home mom).

Here is what I got off of the Alldtadiy website (subscription)

There is a whole list of testing procedures but you need a DRBII scan tool to do the tests.

SYMPTOM
P1762-GOVERNOR PRESSURE SENSOR OFFSET VOLTS TOO LOW OR HIGH

WHEN MONITORED
Continuously with the key ON and the engine running.

SET CONDITION
This code will set if the governor pressure is out of range in park or neutral for 1.3 seconds for three consecutive bad 3.0 second tests and sump temperature > 10 �C (50 �F) and <
127 �C (260 �F) are required to set the code.

POSSIBLE CAUSES
Powertrain control module
Powertrain control module - 5 volt supply high
Powertrain control module - after 5 volt supply shorted to voltage
Powertrain control module - after 5 volt supply shorted to voltage in trans
Repair the 5 volt supply circuit and check the PCM
Replace the trans solenoid assembly and check the PCM
Intermittent condition
Powertrain control module - internal fault
5 volt supply circuit open
Check for other trans DTC's
Governor pressure sensor signal circuit shorted to voltage inside trans
Check trans fluid level and condition
Governor pressure sensor signal circuit shorted to voltage
Park neutral DTC present
5 volt supply circuit shorted to ground
Governor pressure sensor signal circuit shorted to 5 volt supply circuit
Governor pressure sensor signal circuit shorted to 5 volt supply circuit inside trans
Governor pressure sensor signal circuit shorted to ground
5 volt supply circuit shorted to sensor ground
Governor pressure sensor signal circuit open inside trans
Governor pressure sensor signal circuit shorted to sensor ground
GOV pressure sensor signal circuit open
Governor pressure solenoid
Governor pressure sensor signal circuit shorted to ground inside trans
Powertrain control module - 5 volt supply circuit low
Sensor ground circuit open
Transmission line pressure low
Governor pressure sensor signal circuit shorted to sensor ground inside trans
5 volt supply circuit open inside trans
5 volt supply circuit shorted to ground inside trans
5 volt supply circuit shorted to sensor ground inside trans
Sensor ground circuit open inside trans
Governor pressure sensor

hi, im new here. but my 4wd light would stay on at times and would flash at others. i was changing the tranny again. (for the 3rd time) but i noticed one of the red and black vacuum lines was off. it didnt seem to affect the 4wd at all. butafter i hooked it back up there were no more light problems. hope this helps.
