Engine Oil Pressure Sensor

Engine Oil Pressure SensorThe 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 (connector contact "C") of the oil pressure sensor connects to connector contact "8" of the GSC+. 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 programmed into the GSC+ are listed below.

Engine Coolant Temperature SensorThe engine coolant temperature sensor is an input of the GSC+. The engine coolant temperature sensor tells the GSC+ the engine coolant temperature. The GSC+ shows the engine coolant temperature on the lower display. The GSC+ uses the sensor information in order to determine when a high coolant temperature fault exists or a low coolant temperature fault exists. The engine coolant temperature sensor is mounted in the water jacket which is usually toward the front of the engine. The exact location depends on the engine model.The engine coolant temperature sensor is a pulse width modulated type of sensor (PWM). This sensor continuously generates a PWM signal. The PWM duty cycle varies from 10% to 95%. This variation is in a proportion with the engine coolant temperature. The GSC+ receives the PWM signal. Then, the GSC+ measures the duty cycle in order to determine the coolant temperature of the engine. The base frequency of the signal is constant at 455 Hz (370 to 550 Hz). The signal wire (connector contact "C") of the coolant temperature sensor connects to connector contact "7" of the GSC+. The sensor is supplied operating power (8 DCV) at connector contact "A" from the GSC+ (connector contact "9").There are four setpoints that are related to engine coolant temperature. These points are programmed into the GSC+. The related setpoints are listed below.

Engine Oil Temperature SensorThe engine oil temperature sensor is optional. This sensor is an input of the GSC+. The sensor tells the value of the engine oil temperature to the GSC+. The GSC+ shows the engine oil temperature on the lower display. The GSC+ uses the sensor information in order to determine when a high oil temperature fault exists. The engine oil temperature sensor is mounted on the outside of one of the engine oil galleries. The exact location depends on the engine model.The engine oil temperature sensor is a pulse width modulated type of sensor (PWM). This sensor continuously generates a PWM signal. The duty cycle in this signal varies from 10% to 95% in proportion to the oil temperature of the engine. The GSC+ receives the PWM signal. Then, the GSC+ measures the duty cycle in order to determine the oil temperature of the engine. The base frequency of the signal is constant at 455 Hz (370 to 550 Hz). The signal wire (connector contact "C") of the oil temperature sensor connects to connector contact "14" of the GSC+. 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 temperature. These points are programmed into the GSC+. The related setpoints are listed below.

Note: Engine Coolant Fluid Level Sensor is commonly referred as the engine coolant loss sensor.The engine coolant fluid level sensor is optional. The engine coolant fluid level sensor is an input of the GSC+. The sensor tells the GSC+ when the engine has lost coolant. The GSC+ uses the sensor information to determine when a low coolant level fault exists. The engine coolant fluid level sensor is usually mounted near the top of the engine radiator. The exact location depends on the engine model.The engine coolant fluid level sensor sends one of the following signals to the GSC+.
A battery negative signal ("B-") for normal level
+5 DCV signal for a low levelThe signal wire of the coolant fluid level sensor connects to connector contact "13" of the GSC+. The signal wire is connector contact "C" of the coolant fluid level sensor. The sensor is supplied operating power (8 DCV) at connector contact "A" from the GSC+ (connector contact "9").There are three setpoints that are related to engine coolant fluid level. These setpoints are programmed into the GSC+. The related setpoints are listed below.

Engine Speed SensorNote: The engine Speed Sensor is commonly referred as a magnetic pickup sensor.The engine speed sensor is an input of the GSC+. The sensor tells the engine speed to the GSC+. The GSC+ shows the engine speed on the lower display. The GSC+ uses the sensor information for the following tasks: activating an engine overspeed shutdown, terminating engine cranking and determining the oil step speed. The engine speed sensor is mounted on the flywheel housing of the engine.The sensor creates a sine wave signal from passing ring gear teeth at the rate of one pulse per tooth. The sensor sends a sine wave signal to the GSC+. The frequency of this
