Code P0722 2017 GMC Sierra Description

The P0722 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates a problem with the transmission output speed sensor circuit. This means that the vehicle's powertrain control module (PCM) is not receiving a signal from the transmission output speed sensor, also known as the turbine speed sensor. The transmission output speed sensor is responsible for measuring the rotational speed of the output shaft of the transmission. This information is crucial for the PCM to determine shift points, torque converter lockup, and overall transmission performance.
