What vehicles are most commonly affected by B073E?

The B073E code is frequently encountered in vehicles such as the 2015-2019 Ford Edge, but it can also affect other makes and models with similar transmission systems.

How can I prevent B073E from happening again?

Regular maintenance, including fluid changes and inspections of wiring and sensors, can help prevent the recurrence of the B073E code.

What is B073E?

The B073E diagnostic trouble code indicates an issue with the transmission range sensor circuit. This sensor is essential for the proper operation of your vehicle's transmission as it informs the engine control module (ECM) about the current position of the transmission. When the B073E code is triggered, it typically signifies that the ECM is receiving an invalid signal from the transmission range sensor, which can lead to significant performance issues. In practical terms, this means your vehicle may experience erratic shifting, problems with acceleration, or even a complete failure to shift into certain gears. This code is most often seen in vehicles like the 2015-2019 Ford Edge, but it can also appear in other makes and models that utilize a similar transmission setup. Ignoring the B073E code can lead to more serious transmission problems, including potential damage that could lead to costly repairs. Therefore, addressing this code promptly is crucial to maintaining the health of your vehicle's transmission system.

Symptoms

Common symptoms when B073E is present:

  • The check engine light stays illuminated, signaling a potential issue with the transmission system.
  • Drivers may notice that the engine hesitates during acceleration, causing a lack of power when merging or overtaking.
  • Fuel economy may decrease significantly, with reports of a drop by 10-15% due to inefficient shifting.
  • The transmission may slip or fail to engage in certain gears, leading to unpredictable driving behavior.
  • In some cases, the vehicle may enter limp mode, drastically limiting speed and power to protect the transmission.

Possible Causes

Most common causes of B073E (ordered by frequency):

  1. {'cause': 'Faulty transmission range sensor', 'likelihood': '60%', 'details': 'This is the most common reason for the B073E code, where the sensor fails to provide accurate data to the ECM.'}
  2. {'cause': 'Wiring issues or short circuits', 'details': 'Damaged or corroded wiring can disrupt the signal between the sensor and the ECM, leading to the code being triggered.'}
  3. {'cause': 'ECM software issues', 'details': 'In some cases, outdated software can cause miscommunication. Checking for updates may resolve the issue.'}
  4. {'cause': 'Transmission fluid problems', 'details': 'Low or dirty transmission fluid can affect shifting performance and may trigger the B073E code.'}
  5. {'cause': 'Internal transmission failure', 'details': 'Though less common, internal issues such as worn components can lead to sensor misreading and trigger this DTC.'}
