Code P0717 2016 GMC Sierra Description
The P0717 code for a 2016 GMC Sierra indicates a problem with the transmission input speed sensor circuit, specifically that there is no signal being received. The transmission input speed sensor is responsible for monitoring the speed of the input shaft into the transmission. This information is crucial for the transmission control module to determine the appropriate gear shifting and timing. When the sensor fails to send a signal, it can lead to erratic shifting, decreased fuel efficiency, and potential damage to the transmission over time.
Common Causes of P0717 2016 GMC Sierra
- Faulty transmission input speed sensor
- Damaged or corroded wiring/connectors in the sensor circuit
- Issues with the transmission control module
- Electrical problems within the vehicle's system
- Mechanical issues within the transmission itself
Symptoms of P0717 2016 GMC Sierra
- Erratic shifting or delayed gear changes
- Decreased fuel efficiency
- Harsh or rough shifting
- Vehicle going into limp mode (limited speed)
- Check Engine Light illuminated
How to Fix P0717 2016 GMC Sierra
- Begin by diagnosing the issue with a scan tool to confirm the P0717 code and pinpoint the exact cause of the problem.
- Inspect the wiring and connectors associated with the transmission input speed sensor for any damage or corrosion. Repair or replace as necessary.
- Test the transmission input speed sensor itself to determine if it is faulty. Replace the sensor if it is not functioning properly.
- Clear the diagnostic trouble codes from the vehicle's computer and test drive the vehicle to ensure the issue has been resolved.
- If the problem persists, further diagnostic testing may be required to identify any underlying issues with the transmission control module or other components.
