What Does P0715 Mean?
P0715 indicates a problem with the input/turbine speed sensor circuit in the automatic transmission. This sensor monitors the speed of the transmission input shaft.Transmission Control
The TCM uses input speed data along with output speed to determine gear ratios and shift timing. Without it, shifting becomes erratic.Internal Sensor
On most transmissions, this sensor is internal and requires transmission pan removal or more extensive work to access.Related Codes
