Abstract
A system for automatically selecting an oil pressure sensor processing algorithm based on oil pressure sensor type includes an oil pressure sensing device producing an signal indicative of engine oil pressure, and electrically connected to one of an analog and a switch input of a control computer. The control computer is configured to identify the oil pressure sensing device as an analog oil pressure sensor and process the oil pressure signal according a corresponding signal processing algorithm if a voltage level at the analog input is within a predefined voltage range while a voltage level at the switch input is at or near a first voltage level, and to identify the oil pressure sensing device as an oil pressure switch and process the oil pressure signal according a corresponding signal processing algorithm if the voltage level at the switch input is at or near a second voltage level.
