Schematic of the transmission output speed sensor (No. 1)This diagnostic code is recorded when the ECM receives an incorrect output signal from the transmission output speed sensor (No. 1). The signal is below the dropout signal level. The machine must be moving in order to initially log the diagnostic code for the sensor. The incorrect signal that is being read by the ECM has the following characteristics: erratic, intermittent and incorrect. The ECM determines that this condition exists by comparing the information from the signals. The ECM compares the two signals from
