This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer isn't getting a signal from a sensor that checks how fast a part inside the transmission is spinning.
The P0717 code indicates that the transmission control module (TCM) is not receiving a signal from the input/turbine shaft speed sensor A. This sensor measures the rotational speed of the input shaft, which is crucial for proper transmission operation.
The input/turbine shaft speed sensor A is responsible for providing the TCM with the rotational speed of the transmission's input shaft. This data is used to control shift timing and torque converter lock-up. When the TCM detects no signal from this sensor, it triggers the P0717 code.
• Check Engine Light is on
• Transmission slipping
• Harsh or erratic shifting
• Faulty input/turbine shaft speed sensor
• Damaged wiring or connectors
• Faulty transmission control module (TCM)
TCM: Transmission Control Module

• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the input/turbine shaft speed sensor for proper operation.
• Replace the input/turbine shaft speed sensor.
• Repair or replace damaged wiring or connectors.
• Replace the transmission control module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Malibu
• Ford F-150
• Toyota Camry
• Regular transmission maintenance
• Inspect wiring and connectors periodically
• Avoid harsh driving conditions
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Avoid driving the vehicle if transmission issues are severe.
Check your vehicle's warranty for coverage on transmission components.
The P0717 code has been a common issue in vehicles with automatic transmissions, often due to sensor failure or wiring issues.
Moderate – While the vehicle may still be drivable, ignoring this issue can lead to more severe transmission problems.
Driving with a faulty transmission sensor can lead to unsafe driving conditions. Always address Check Engine Light issues promptly.
• Vehicle must be running
• Transmission at operating temperature
The input/turbine shaft speed sensor is typically located inside the transmission housing, near the input shaft.
Q: Can I drive with a P0717 code?
A: It's not recommended as it could lead to further transmission damage.
Q: How do I reset the P0717 code?
A: After repairs, use an OBD-II scanner to clear the code.
