Abstract
A method for coolant pump flow rationalization using coolant pump parameters includes calculating a first pump coolant flow based on a coolant input pressure sensor signal and the coolant pump speed. Further, the method includes calculating a second pump coolant flow based on coolant pump current and coolant pump speed when the first pump coolant flow is greater than a predetermined threshold; and comparing the first pump coolant flow with the second pump coolant flow to rationalize the coolant pressure sensor signal.
