P0716: Input/Turbine Speed Sensor A Circuit Range/Performance

What does P0716 mean?

The transmission input/turbine speed signal does not match expected operation. The controller compares input and output rotation to manage shifts and detect slip, so an implausible sensor can resemble a mechanical problem.

Generic OBD-II definition: Input/Turbine Speed Sensor A Circuit Range/Performance. Confirm applicability in your vehicle service information.

Common causes

• Faulty input-speed sensor
• Damaged wiring or connector
• Contaminated pickup or a trigger-wheel issue

Symptoms

• Harsh or erratic shifts
• Limp mode
• Reduced fuel economy

Diagnostic focus

Check that both speed inputs are trustworthy before calculating a gear ratio. A bad output signal can make a good input signal appear implausible.

Can I keep driving with P0716?

Severity: Medium Avoid towing, steep loads, and prolonged driving until diagnosed. Stop and arrange recovery if the transmission slips, loses drive, overheats, or bangs into gear; driving through slip can cause further damage.

If the check engine light is flashing or the car runs badly, stop driving and have it checked.

Typical fixes

• Compare input speed, output speed, and selected gear
• Inspect the sensor harness and pickup
• Verify the signal before diagnosing internal slip
