Codes P0720 and P0722 on a 2001 7.3L diesel typically relate to issues with the vehicle's speed sensor. P0720 indicates a malfunction in the output shaft speed sensor circuit, while P0722 signals that the output shaft speed sensor is providing a low signal. These codes can lead to transmission shifting issues and may require inspecting the sensor, wiring, and connectors for faults.
