Hello, Honda calls the Input shaft speed sensor a Main shaft speed sensor and the Output speed sensor which would set a P0720 is called a Countershaft speed sensor, Ill post diagrams of where they are. They also have a vehicle speed sensor, which they have a ratio between the main shaft speed sensor and the vehicle speed sensor that is calculated and if it's within a specific range it will set the P0715. Hopefully I have that all correct, so I assume your speedometer is working correctly? You are just getting a check engine light and the p0715?
I'm posting the p0720 just so you can see it considered the output shaft speed sensor.
