P0722 Output Speed Sensor Circuit No Signal - General Information

Component Location





General Description

Output speed sensor detects vehicle speed from rotation number of parking lock gear and transmits to TCU as a signal. This value, together with the throttle position data, is mainly used to decide the optimum gear position.

DTC Description

TCM sets this DTC if output speed sensor signal is not detected even though, vehicle is driving over 30 km/h. TCM sets fail safe mode if this DTC is detected. During the TCM intermal process to judge this DTC, Shift Lock, which is safety function for controlling to keep neutral when shifting to Reverse by accident, is performed while driving the vehicle over 11 km/h.
