DTC Set Conditions

If the output from the output shaft speed sensor is continuously 50 percent lower than the vehicle speed for one second or more while driving in 3rd or 4th gear at a speed of 30 km/h (19 mph) or more, it is judged that an open circuit or short circuit in the output shaft speed sensor circuit and DTC 23 is set. If DTC 23 is set consecutively four times, the transmission is locked into 3rd gear or 2nd gear as a fail-safe measure, and the "N" range light flashes once per second.
