What is B0717?

The diagnostic trouble code B0717 indicates a problem with the transmission fluid temperature sensor circuit's range or performance. This sensor is crucial because it monitors the temperature of the transmission fluid, which helps the vehicle’s control module adjust shifting patterns to optimize performance and prevent overheating. When the B0717 code is triggered, it usually means that the sensor is sending readings that are outside the expected range, which can lead to erratic transmission behavior and potential damage if not addressed. Common symptoms include harsh shifting, slipping gears, or even complete transmission failure in severe cases. This code is often found in popular models like the 2013-2018 Ford F-150 and the 2014-2019 Chevrolet Silverado. Ignoring this code could result in costly repairs down the line, as the transmission may overheat and fail if it is not properly monitored. In summary, B0717 signals a serious issue that should be diagnosed and repaired promptly to maintain vehicle reliability and performance.

Symptoms

Common symptoms when B0717 is present:

  • Check engine light illuminates and remains on, indicating the need for a diagnostic check.
  • Harsh or erratic shifting can be felt during acceleration, leading to discomfort while driving.
  • Transmission may slip out of gear unexpectedly, causing a loss of power and control.
  • Decrease in fuel efficiency, often noticeable as a drop of 10-15% due to poor shifting performance.
  • In severe cases, overheating of the transmission can lead to complete failure, requiring costly repairs.

Possible Causes

Most common causes of B0717 (ordered by frequency):

  1. Faulty transmission fluid temperature sensor - 40% likelihood, often caused by wear and tear or electrical issues.
  2. Wiring issues or poor connections within the sensor circuit - 30% likelihood, typically due to corrosion or damage.
  3. Low transmission fluid level - 20% likelihood, which can result from leaks or improper maintenance.
  4. Failed transmission control module - 5% likelihood, a more serious issue that can lead to extensive repairs.
  5. Rarely, software issues within the vehicle’s control unit can cause false readings - 5% likelihood, often resolved with a software update.
