What is B071E?

The B071E Diagnostic Trouble Code (DTC) indicates a problem with your vehicle's transmission range sensor, which plays a crucial role in ensuring that your automatic transmission operates smoothly. Specifically, this code signals that the transmission control module (TCM) has detected an abnormal input from the sensor, which is responsible for detecting the gear position of the transmission. This can lead to various issues, such as difficulty in shifting gears, unexpected behavior during acceleration, or even a complete failure to shift into gear at all. Notably, this issue is commonly seen in vehicles such as the 2015-2019 Ford F-150, but can also affect other makes and models that utilize similar transmission systems. If left unaddressed, a B071E code can lead to severe transmission problems, increased wear and tear, and ultimately higher repair costs. Therefore, it is essential to diagnose and resolve the underlying issues promptly. Understanding the implications of this code can help car owners take proactive steps to maintain their vehicles and ensure safe operation on the road.

Symptoms

Common symptoms when B071E is present:

  • The check engine light illuminates and remains on, indicating a potential issue with the transmission system.
  • Shifting gears becomes erratic, causing the vehicle to hesitate or jerk during acceleration, which can be alarming for drivers.
  • You may notice a significant decrease in fuel economy, with reports of up to 15% reduced efficiency due to improper gear engagement.
  • Transmission may fail to engage or disengage properly, leading to issues like getting stuck in gear or the vehicle rolling unexpectedly.
  • You might experience unusual noises from the transmission, such as grinding or whining, when trying to shift or accelerate.

Possible Causes

Most common causes of B071E (ordered by frequency):

  1. The most common cause is a faulty transmission range sensor, which accounts for approximately 60% of B071E occurrences. This sensor may fail due to wear and tear or electrical issues.
  2. A second cause could be damaged wiring or connectors related to the sensor, which can disrupt the electrical signals necessary for proper operation.
  3. A third possibility is low transmission fluid levels, which can lead to overheating and premature wear of the transmission components. Regular checks can help prevent this.
  4. A less common but serious cause could be a malfunctioning transmission control module (TCM), which is responsible for interpreting signals from the range sensor.
  5. Lastly, a rare cause may involve internal transmission problems, such as worn gears or clutches, necessitating more extensive repairs or a transmission rebuild.
