Code P0717 2016 Chevrolet Silverado Description
The P0717 code indicates that the Engine Control Module (ECM) has detected a lack of signal from the Transmission Input Speed Sensor (TISS). This sensor plays a critical role in the vehicle's transmission system, as it measures the rotational speed of the input shaft, which is essential for the transmission control module (TCM) to manage shifting and optimize performance. When the TISS fails or sends no signal, it can lead to erratic shifting behavior, poor fuel economy, and can even cause the vehicle to enter "limp mode," where it restricts power to protect the engine and transmission.
Common Causes of P0717 2016 Chevrolet Silverado
- A faulty Transmission Input Speed Sensor that is unable to send a signal.
- Damaged or corroded wiring or connectors in the sensor circuit.
- Internal transmission issues, such as a malfunctioning torque converter or worn components.
- A malfunctioning Engine Control Module (ECM) or Transmission Control Module (TCM).
- Low transmission fluid levels or contaminated fluid affecting sensor operation.
Symptoms of P0717 2016 Chevrolet Silverado
- Erratic or harsh shifting of the transmission.
- Delayed engagement when shifting from park to drive or reverse.
- Activation of the check engine light.
- Poor acceleration and reduced fuel efficiency.
- The vehicle may enter limp mode, limiting speed and power.
How to Fix P0717 2016 Chevrolet Silverado
- Diagnostic Testing: Begin with a thorough diagnostic scan to confirm the P0717 code and check for any additional codes that may provide more context.
- Visual Inspection: Inspect the wiring and connectors associated with the Transmission Input Speed Sensor for any signs of damage, corrosion, or loose connections.
- Sensor Replacement: If the sensor is determined to be faulty, replace it with a new, OEM-quality sensor to ensure proper functionality.
- Wiring Repair: If wiring issues are found, repair or replace damaged wires and connectors to restore proper signal transmission.
- Fluid Check: Check the transmission fluid level and condition. If the fluid is low or contaminated, perform a fluid change and top off to the appropriate level.
Cost to Fix P0717 2016 Chevrolet Silverado
The cost to repair a P0717 code can vary widely based on the specific issue and the labor rates in your area. On average, you can expect to pay between $150 and $400 for parts and labor. This estimate includes the cost of a new Transmission Input Speed Sensor, which typically ranges from $50 to $150, plus labor costs that can vary from $80 to $150 per hour. Keep in mind that labor rates may be higher at dealerships or in metropolitan areas, while independent shops may offer lower rates. It is advisable to obtain quotes from local repair shops for a more accurate estimate tailored to your specific situation.
