Code P0722 Acura Description
The P0722 code for Acura vehicles indicates that the Output Shaft Speed Sensor is not sending a signal to the Engine Control Module (ECM). The Output Shaft Speed Sensor is a crucial component in the vehicle's transmission system, as it monitors the speed of the transmission output shaft. This information is used by the ECM to determine the appropriate shifting strategy for the transmission. When the sensor fails to send a signal, the ECM is unable to accurately control the transmission, leading to potential performance issues.
