Pressure Sensor (Engine Oil)The engine oil pressure sensor is an input of the GSC. The sensor tells the GSC the current engine oil pressure. The GSC shows the engine oil pressure on the lower display and the GSC also uses the sensor information to determine when a low engine oil pressure fault exists. The engine oil pressure sensor is mounted on the outside of one of the engine oil galleries. The engine model determines the exact location of the engine oil pressure sensor.The engine oil pressure sensor is a pulse width modulated sensor. This sensor continuously generates a PWM signal. The duty cycle of the PWM signal varies from 10 to 90%. The duty cycle varies proportionally to the oil pressure of the engine. The GSC receives the PWM signal. The GSC measures the duty cycle in order to determine the oil pressure of the engine. The base frequency of the signal is constant at 500 150 Hz. The signal wire of the oil pressure sensor connects to connector contact 8 of the GSC. The signal wire of the oil pressure sensor is found on connector contact "C". The sensor is supplied operating power (8 DCV) at connector contact "A" from the GSC (connector contact 9).There are five setpoints that are related to engine oil pressure. The setpoints that are
