What Does P0716 Mean?
The input/turbine speed sensor A is reporting a signal that is outside the expected range or does not correlate properly with other speed and gear data. This sensor measures the rotational speed of the transmission input shaft (turbine), and incorrect readings prevent the TCM from calculating gear ratios, slip, and shift points accurately. The driver may notice erratic shifting, flaring between gears, or transmission slipping sensations.
Common Causes
30%
Faulty input/turbine speed sensor producing erratic or out-of-range signal
25%
Damaged or corroded wiring and connectors in the sensor circuit
20%
Contaminated or damaged reluctor ring/tone wheel on the input shaft
15%
Incorrect sensor air gap (excessive clearance between sensor and reluctor)
10%
Internal transmission mechanical issue affecting input shaft speed
Diagnostic Steps
1
Monitor the input/turbine speed sensor (ISS/TSS) PID in live data while driving. Compare it to the output speed sensor and engine RPM — the input speed should be proportional to engine RPM based on the torque converter and selected gear.
2
With the vehicle in gear at steady speed, verify that the ISS reading is stable and does not jump or drop out. Erratic readings indicate a sensor or reluctor issue.
3
Inspect the sensor connector for corrosion, moisture, or damaged pins. Check the sensor mounting for correct installation and air gap (typically 0.030-0.050 inches from the reluctor).
4
Remove the sensor and inspect the tip for metallic debris contamination. Also visually inspect the reluctor ring (if accessible) for damaged, chipped, or missing teeth.
5
Measure the sensor resistance (typically 300-1,200 ohms for a magnetic pickup type). Also check for AC voltage output by spinning the input shaft or during a test drive (should produce a clean, proportional AC signal).

The most common cause of P0716 (Input/Turbine Speed Sensor A Circuit Range/Performance) is: Faulty input/turbine speed sensor producing erratic or out-of-range signal
Typical repair costs for P0716 range from $100 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Driving with a faulty input speed sensor can cause erratic or harsh shifts, which may be startling. The TCM may enter limp mode, limiting the vehicle to one gear. Avoid highway driving if shifts are unreliable. Repair promptly.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0716 to identify the root cause.
