(4) Torque converter oil temperature sensorWith the key start switch in the ON position, 24 volt power is supplied from the batteries via circuit breaker 13 to Caterpillar Monitoring System ECM (1). Caterpillar Monitoring System ECM (1) supplies 8 volt power to torque converter oil temperature sensor (4) .Torque converter oil temperature sensor (4) sends a Pulse Width Modulated (PWM) signal to Caterpillar Monitoring System ECM (1). Caterpillar Monitoring System ECM (1) sends a signal to gauge module (2). The torque converter oil temperature is displayed on torque converter oil temperature gauge (3) .ReferenceFor more information on torque converter oil temperature, refer to Operation and Maintenance Manual, "Caterpillar Monitoring System".
