Yes, it appears thats where things are going. When I clear the codes, it the pressure switch code that I keep getting, and I think its possible that the charge pump-accumulator might be the culprit or maybe some wiring issue, and the Pump itself is spinning well when direct current is applied, but its not pumping any fluid.
