Code P0717 2017 GMC Sierra Description
The P0717 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates a problem with the Transmission Input Speed Sensor Circuit, specifically a lack of signal being received by the vehicle's onboard computer. The input speed sensor is responsible for monitoring the speed of the transmission input shaft, providing crucial data for the transmission control module (TCM) to determine shift points, torque converter lock-up, and other transmission functions. When the TCM does not receive a signal from the input speed sensor, it can lead to erratic shifting, poor performance, and potential damage to the transmission system.
