Yoh!  Difficult question.  Unfortunately with these pumps it is very much a matter of trial and error.  I would replace the sensor to start with.

The GS-911 Bleed test is just that. A test to see if you have any trapped air in the system AFTER you performed the physical bleed operation.

The following is just one of a number of explanations on how to perform the actual bleed sequence.

Agreed.  This is one of the best write-ups for bleeding these systems.
