P0716
Input/Turbine Shaft Speed Sensor A Circuit Range/Performance
Transmission
Generic OBD-II
High
What it means
P0716 means the input (turbine) shaft speed sensor is giving a reading that is out of range or does not match what the transmission expects. The TCM uses this sensor to time shifts and torque-converter lockup, so an unreliable signal causes harsh or erratic shifting, slipping, or a protective limp mode. It points at the sensor, its wiring, or the transmission fluid — not at the engine's ability to start.
High
Can I keep driving? The transmission may shift harshly, slip, or drop into limp mode — driveable slowly, but avoid extended driving until it is fixed.
Common symptoms
What you'll notice
- Check-engine light on (sometimes a transmission warning light)
- Harsh, erratic, or delayed shifting
- Transmission slipping or flaring between gears
- Limp mode locking the transmission in one gear
Common causes
Most likely first
- Faulty input/turbine speed sensorLikely
- Damaged wiring or a corroded connector at the sensorCommon
- Debris on the sensor tip or a damaged reluctor/tone ringCommon
- Low or degraded transmission fluid affecting the signal; less commonly a failed TCMLess often
How to diagnose & fix
Work through it in order
- Scan and record freeze-frame data, and compare input vs. output speed readings to confirm the input sensor is out of range.
- Check the transmission fluid level and condition, since low fluid can distort the signal.
- Inspect the sensor's connector and wiring for damage or corrosion; clean the sensor tip if accessible.
- Replace the input/turbine speed sensor if its signal stays erratic with good wiring; consider the TCM only after the sensor and harness are ruled out.
FAQ
Quick answers
Is it safe to drive with P0716?+
Short, slow trips may be fine, but slipping and limp mode can strain the transmission. Have it diagnosed before extended driving.
Can I just clear P0716?+
It clears, but returns once the sensor signal faults again, and it can drop the transmission back into limp mode. Fix the sensor or wiring first.
