Signal Path

ECM calculates an engine oil pressure according to a signal transmitted from the engine oil pressure sensor. When the engine oil pressure is low, ECM transmits the engine oil pressure warning lamp signal to combination meter via CAN communication. Then the engine oil pressure warning lamp illuminates.
