EEXV is not working correctly.
It’s not opening enough or it’s moving
in the opposite direction.
Check if pump-down can be finished
for pressure limit reached;
Check expansion valve movements.
Check connection to the valve driver
on the wiring diagram.
Measure the resistance of each
winding, it has to be different from 0
Ohm.

Sensor is broken.
Check for sensor integrity.
Check correct sensors operation
according information about mVolt
(mV) range related to pressure values
in kPa.
Sensor is shorted.
Check if sensor is shorted with a
resistance measurement.
Sensor is not properly connected
(open).
Check for correct installation of the
sensor on refrigerant circuit pipe. The
transducer must be able to sense the
pressure through the valve’s needle.
