Input/Turbine Shaft Speed Sensor A Circuit Range/Performance
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.
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.
Real-world scan data
Figures reflect only diagnostic scans recorded through our own apps and tools. Cars are typically scanned because a symptom or warning light prompted it, so these counts describe our scan records — not the incidence of faults in any model, and not the quality, reliability, or safety of any vehicle. No comparison between manufacturers or models is implied. All trademarks belong to their respective owners; no affiliation or endorsement is implied.
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.
