Engine Oil Level Sensor
Illustration 1 g06191182
Location of engine oil level sensor (see arrow)
The sensor will report a low resistance when oil is present in the tank. When sufficient fluid is not present, the sensor will not complete the electrical circuit (open condition). The sensor requires a voltage between 4.5 VDC and 36 VDC for proper operation. The sensor is designed to test for an oil level in relation to the location of the sensor.The Engine Oil Level sensor is located near the base of the engine oil pan. The sensor view is from the perspective of the left side and underside of the machine.Steering Fluid Level Sensors

Location of the steering fluid sensors
(1) Fluid Level sensor
(2) Fluid Temperature sensorThe oil level sensor will report a low resistance when oil is present in the tank. When sufficient fluid is not present, the sensor will not complete the electrical circuit (open condition). The sensor requires a voltage between 4.5 VDC and 36 VDC for proper operation. The sensor is designed to test for an oil level in relation to the location of the sensor.The temperature sensor is designed to operate in a range from 120° C (248° F) to −40° C (−40° F). The input voltage required for the sensor is 7.5 VDC to 8.5 VDC (8 V nominal). The sensor is a pulse width modulated sensor operating a frequency of 500 200 Hz. At a low duty cycle (approximately 10%), the corresponding temperature is around −40° C (−40° F). At a high duty cycle (approximately 90%), the corresponding temperature is around 120° C (248° F).The Steering Fluid sensors are on the top deck of the machine to the right of the operator cab.Torque Converter Oil Level Sensor

Location of torque converter oil level sensor (see arrow)
The oil level sensor will report a low resistance when oil is present in the tank. When sufficient fluid is not present, the sensor will not complete the electrical circuit (open condition). The sensor requires a voltage between 4.5 VDC and 36 VDC for proper operation. The sensor is designed to test for an oil level in relation to the location of the sensor.The Torque Converter Oil Level sensor is on the lower left side of the Torque Converter reservoir tank. (The torque converter is a component of the transmission system.)Engine Coolant Sensor

(3) Coolant Level sensor
(4) Coolant Temperature sensorThe oil level sensor will report a low resistance when oil is present in the tank. When sufficient fluid is not present, the sensor will not complete the electrical circuit (open condition). The sensor requires a voltage between 4.5 VDC and 36 VDC for proper operation. The sensor is designed to test for an oil level in relation to the location of the sensor.The engine coolant temperature sensor is an analog type sensor (signal and ground connection only). The operating range for the temperature sensor is between −40° C (−40° F) and 150° C (302° F). As the temperature at the sensor
