P0716 — Input/Turbine Speed Sensor Circuit Range/Performance
Drive with caution — fix soon.
What P0716 means
This code means the transmission computer sees an input (turbine) speed sensor reading that's outside the expected range or doesn't make sense compared to other sensors. Common causes include a failing input speed sensor, wiring or connector faults, or low and dirty transmission fluid. Repairs typically involve replacing the sensor or fixing the wiring, and are usually less costly than internal transmission repairs.
Common symptoms
- Check Engine light is on
- Harsh, erratic, or delayed shifting
- Transmission slips or shifts at the wrong times
- Transmission enters limp mode (limited gears)
- Hesitation or jerking during acceleration
Common causes
- Faulty input/turbine speed sensor
- Damaged or corroded wiring to the sensor
- Loose or poor electrical connector
- Low, dirty, or contaminated transmission fluid
- Internal transmission fault affecting the signal
Typical repair cost
$100 – $500
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0716 code?
Short trips are usually okay, but don't ignore it. The faulty speed signal can cause harsh shifting or limp mode, which is hard on the transmission, so have it checked soon.
How much does it cost to fix a P0716?
It's often a relatively affordable fix. Replacing the input speed sensor and any related wiring typically costs about $100 to $500, depending on how accessible the sensor is.
Is a P0716 code serious?
It's moderately serious. The car usually still drives, but the unreliable signal can lead to erratic shifting and limp mode, so it's best not to leave it for long.
What does the input speed sensor actually do?
The input (turbine) speed sensor measures how fast the transmission's input is spinning, which the computer compares to output speed to control shift timing and detect slipping, so a bad reading throws off the whole shift strategy.
