What vehicles are most commonly affected by B06AF?

DTC B06AF is commonly found in models like the 2015-2020 Ford F-150, Ford Explorer, and certain models of the Ford Fusion. It's important to check for any recalls or technical service bulletins related to this code.

How can I prevent B06AF from happening again?

Regular maintenance of your vehicle, including transmission fluid changes, inspecting wiring and connectors, and ensuring all parts are properly installed, can help prevent the recurrence of B06AF.

What is B06AF?

DTC B06AF is a diagnostic trouble code that indicates a malfunction within the vehicle's transmission control system, specifically related to the transmission range sensor. This code is often triggered when the vehicle's computer detects an inconsistency between the gear selected by the driver via the gear shifter and the actual position of the transmission. The transmission range sensor is crucial for ensuring smooth gear transitions and proper vehicle operation. When this sensor fails or sends erroneous signals, the vehicle may experience issues such as difficulty shifting gears, unexpected changes in power delivery, or even stalling. For drivers of vehicles like the 2015-2020 Ford F-150, this could lead to decreased performance and safety concerns if left unaddressed. It’s essential for car owners to understand that ignoring this code might lead to further transmission damage, resulting in more costly repairs. In some cases, it can trigger the check engine light, prompting a visit to a mechanic. Therefore, recognizing the symptoms and causes associated with DTC B06AF can help in timely repairs and maintaining vehicle reliability.

Symptoms

Common symptoms when B06AF is present:

  • The check engine light may illuminate and stay on, indicating a problem with the transmission system.
  • Drivers may experience difficulty shifting gears, such as the vehicle refusing to shift into higher gears or slipping out of gear unexpectedly.
  • Fuel economy may decrease significantly, with some drivers reporting drops of up to 15% due to inefficient gear engagement.
  • Unusual transmission noises like grinding or whining while changing gears can also occur, which may indicate further issues.
  • In severe cases, the vehicle may enter 'limp mode,' restricting power and speed to prevent damage.

Possible Causes

Most common causes of B06AF (ordered by frequency):

  1. The most common cause of DTC B06AF is a faulty transmission range sensor, likely accounting for about 60% of cases. This sensor can wear out over time or become misaligned, leading to incorrect readings.
  2. Another cause could be wiring issues, such as damaged or corroded wires connecting the sensor to the vehicle's computer, which can disrupt signal transmission.
  3. Improper installation of the transmission or related components can lead to alignment issues, causing the sensor to misinterpret gear positions.
  4. Less commonly, transmission fluid contamination can lead to sensor malfunction, which can affect various transmission components.
  5. A rare but serious cause could be a failing transmission control module (TCM), which may require a full replacement to resolve the issue.
