Connections for the transmission speed sensor 2
This diagnostic code is associated with the Transmission Output Speed Sensor 2. The CID 0673 FMI 02 is recorded when the Power Train ECM reads the speed sensor signal as being erratic, intermittent, or incorrect. There are two speed sensors for transmission output speed: the transmission output speed sensor 1 and the transmission output speed sensor 2. The Power Train ECM determines the existence of this diagnostic code by comparing the signals from sensor 1 and the signals from sensor 2. This diagnostic code is recorded when one of the sensors shows a valid speed signal above the minimum. The other sensor signal is below the dropout signal level.Note: Failures of the transmission output speed sensor will be shown only while the machine is moving.The transmission speed sensors are mounted by a fixed mounting arrangement. When the sensor is mounted securely, no adjustment is necessary.The possible causes of this diagnostic code are listed below:
The signal circuit is shorted
