What is B064E?

The diagnostic trouble code (DTC) B064E indicates an issue with the vehicle's airbag system, specifically related to the passenger seat occupancy sensor. This code is commonly found in various Ford and Lincoln models, especially those produced between 2015 and 2020. When the B064E code is triggered, it typically means that the airbag control module has detected an anomaly in the input from the passenger seat sensor. This sensor is essential for determining whether the passenger airbag should deploy in the event of a collision. If the system identifies that the sensor is malfunctioning, it may prevent the airbag from deploying, which is a significant safety concern. Ignoring this code can lead to increased risk during an accident, as the airbag may not function as intended, potentially resulting in severe injuries. For vehicle owners, this code usually manifests as an illuminated airbag warning light on the dashboard, prompting immediate attention. Diagnosing and addressing the B064E code is crucial for maintaining airbag functionality and ensuring safety features are operational. It’s advisable to consult with a certified technician who can perform thorough diagnostics and repairs to ensure the airbag system is reliable.

Symptoms

Common symptoms when B064E is present:

  • The airbag warning light illuminates on the dashboard, indicating a fault in the airbag system.
  • Passenger airbag may not deploy during an accident, posing a serious safety risk.
  • The vehicle may produce a chime or warning message related to airbag functionality when the ignition is turned on.
  • Inconsistent readings from the passenger seat sensor, potentially causing the airbag system to misidentify whether a passenger is present.
  • In some cases, the vehicle might experience issues with the seat belt warning system, indicating a faulty connection.

Possible Causes

Most common causes of B064E (ordered by frequency):

  1. The most common cause is a faulty passenger seat occupancy sensor, which occurs in approximately 60% of reported cases. This sensor may wear out or become damaged over time due to regular use.
  2. Another frequent cause is damaged wiring or poor connections within the airbag system, accounting for about 25% of cases. This can happen due to wear and tear, moisture exposure, or improper installation of aftermarket seats.
  3. A less common cause, but still significant, is a malfunctioning airbag control module, which can lead to improper airbag deployment. Regular diagnostics can prevent these issues from escalating.
  4. In rare cases, a complete failure of the airbag system can occur due to software issues or a fault in the vehicle’s onboard computer, which can be difficult to diagnose.
  5. Improperly installed or aftermarket seat replacements can also trigger the B064E code, particularly if they interfere with the original sensor's operation.
