What is B0737?

The diagnostic trouble code (DTC) B0737 indicates an issue with the transmission range sensor, which plays a crucial role in determining the correct gear for your vehicle. This sensor is responsible for communicating the position of the gear selector to the Engine Control Module (ECM) or Transmission Control Module (TCM). When the B0737 code is triggered, it means that the sensor's output is not within the expected range, which can lead to improper shifting, poor acceleration, or even the inability to shift into certain gears. The most common vehicles affected by this code include various models from Ford (especially those from the 2015-2019 Ford Fusion) and Chrysler (such as the 2016-2018 Dodge Charger). If your vehicle displays this code, you may experience symptoms like the check engine light illuminating, hesitation during acceleration, or unusual transmission behavior. Ignoring this code can result in increased wear on the transmission, reduced fuel efficiency, and can even lead to complete transmission failure if not addressed promptly. Therefore, understanding and resolving the B0737 code is essential for maintaining the performance and safety of your vehicle.

Symptoms

Common symptoms when B0737 is present:

  • Check engine light stays on constantly, indicating a transmission issue that needs attention.
  • Engine hesitates during acceleration, causing a noticeable delay in response when pressing the gas pedal.
  • Fuel economy decreased by 10-15%, reflecting a potential problem with the transmission's efficiency.
  • Rough shifting between gears, leading to uncomfortable driving experiences and potential safety risks.
  • Transmission may not shift into certain gears, limiting your vehicle's performance and driving capability.

Possible Causes

Most common causes of B0737 (ordered by frequency):

  1. The most common cause is a faulty transmission range sensor, accounting for around 60% of cases. This sensor can fail due to wear, moisture exposure, or electrical issues.
  2. A second cause could be damaged wiring or connectors related to the sensor. Corrosion or frayed wires can disrupt the signal, leading to B0737.
  3. Thirdly, low transmission fluid levels or contamination can affect sensor performance. Regular checks and maintenance can prevent this issue.
  4. Less common but serious causes include internal transmission failures that can lead to significant repair costs if not caught early.
  5. A rare cause may be a software glitch in the vehicle’s ECM or TCM, which may require a software update or reprogramming.
