What P0716 Means
The transmission's input (turbine) speed sensor, which tracks how fast the input shaft is spinning, is sending a signal outside the expected range.
Common Causes
- Faulty input speed sensor
- Damaged or corroded wiring/connector
- Low or contaminated transmission fluid affecting internal sensor performance
- Internal transmission wear (less common, more serious)
Symptoms You Might Notice
- Harsh, delayed, or erratic shifting
- Transmission may enter a protective 'limp' mode
- Check engine or transmission warning light on
What to Check First
- 1
Check transmission fluid level and condition first
- 2
Inspect the sensor's wiring and connector for external damage
- 3
A transmission specialist will typically need to test the sensor with dedicated equipment, since it's usually mounted inside the transmission housing
