The OUTPUT SPEED SENSOR(PG-B) outputs waveform signals according to the revolutions of the output shaft of the transmission. The OUTPUT SPEED SENSOR(PG-B) is installed in front of the Transfer Drive Gear and determine the Transfer Drive Gear rpms by calculating the frequency of the pulses. This value, together with the throttle position data, is mainly used to decide the optimum gear position.
The PCM/TCM sets this code if the calculated value of the signals is noticeably different from the value calculated, using the Vehicle Speed Sensor output, when the vehicle is running faster than 30 km/h. The PCM/TCM will initiate the fail safe function if this code is detected.
