ABSTRACT:
An engine oil pressure monitor includes an engine oil pressure sensor and an engine speed sensor. A plurality of pressure alarm values are generated to correspond to designated distinct ranges of engine speed. One of the alarm values is selected according to which engine speed range contains the sensed engine speed. An alarm signal is generated when the sensed pressure falls below the alarm value. The alarm is disabled when the engine speed falls below a minimum non-zero engine speed and is disabled unless the pressure failure condition persists for at least a predetermined time period.
