these are not sensors they are solenoids an are controlled by the TCM an all are located inside the transmission !

Detailed information on diagnosing...
P0748 Jeep Governor Pressure Solenoid Circuit...
The governor pressure solenoid valve...
P1765 Dodge Gov Press Not Equal to Target not15 20...
Possible Causes and Repair...
The transmission cods P07xx
it can be as simple as a wire fell off a solenoid, or pin rusty
to transmission slip.
the tests to find this are complex.
are you up to that
or read the FSM book, it covers this, in vivid complex details
so>?
try to void, all problems in live (or car) are bad sensors.
most times sensor are good, but the data the send is bad.
and is bad because, for example the transmission slips.
its reporting the truth. so... we do the on car tests shown in the FSM> ever seen one?
click ZJ

and see on car tests.
scan it, done
stall test pass.
the test drive pass? no slips. flogged hard ?
does the line pressure test pass.
solenoid coil resistances read right?

when diagnosing multiple fault codes it can be tricky figuring out whats going on for instance all three of the codes you have are an electrical nature and not mechanical faults in the transmission most likely they share a common power or ground circuit and have lost one or the other also if they do share any circuit and anyone of these are faulty it would generate the other codes. to do an accurate circuit check you should remove the transmission pan so you can check the terminals at the solenoids and switches on the valvebody because the problem could be in the "passthrough" connector
