P0716: Input/Turbine Speed Sensor Circuit Range/Performance
Severity: medium
What it means: The transmission computer sees a turbine (input) speed signal that doesn't make sense. On some cars it's a real sensor or wiring problem; on 2018–2019 Honda Odysseys with the 9-speed, Honda says it can come from software and adaptation values.
Safe to drive? Usually drivable to the shop, but harsh shifts or a transmission warning should be checked soon.

DIY or shop?
Shop. It needs a scan tool and often a software update.
Before you replace parts
- Read all stored codes and freeze-frame data.
- Check your VIN for transmission software bulletins.
- Check the transmission fluid level and condition.
- After a software update, allow time for the transmission to relearn.
Safety / mechanic note
Verify with a mechanic. Harsh shifting can make the car lurch. A code points to a circuit or system, not always a specific part.
