Hi Richxantan,
Did you check the cooling water temperature ? sometimes the Cooling water temp. causes this alarm.
Secondly did you install the Pressure Transducer correctly ? hope it is not faulty ( though it is new).
did you loose the PHNC parameters by any chance..? if so try restoring the parameters.

please chk n revert.

thanks.

If your servo valve is faulty. The spool may shift to one side, bleeding all the pressure from the manifold. Your display will read 0. We need more details to help.
