What vehicles are most commonly affected by B0907?

B0907 is commonly found in vehicles such as the 2013-2017 Ford Escape and the 2014-2018 Nissan Rogue. If you own one of these models, be aware of this potential issue and monitor for symptoms like an illuminated airbag warning light.

How can I prevent B0907 from happening again?

To prevent the B0907 code from recurring, regularly inspect the seat adjustments and wiring for signs of wear or damage. Avoid forcing the seat adjustments and ensure that any repairs are performed by qualified professionals.

What is B0907?

The diagnostic trouble code (DTC) B0907 refers to a problem with the seat position sensor circuit. This code is typically triggered when the Powertrain Control Module (PCM) detects that the seat position sensor is malfunctioning or that there is a communication issue within the circuit. The seat position sensor is crucial for the proper functioning of the airbag system, as it helps determine the positioning of the driver's seat to ensure that airbags deploy correctly during an accident. If this sensor is faulty, it can lead to the airbags not deploying or deploying improperly, significantly increasing the risk of injury in a collision. Furthermore, this code may also cause the airbag warning light to illuminate on your dashboard, indicating that there's a safety issue that needs immediate attention. Common vehicles affected by this issue include the 2013-2017 Ford Escape and 2014-2018 Nissan Rogue. Ignoring the B0907 code can result in serious safety risks and higher repair costs down the line, therefore addressing it promptly is crucial for your safety and the safety of your passengers.

Symptoms

Common symptoms when B0907 is present:

  • The airbag warning light remains illuminated on the dashboard, indicating a fault in the airbag system.
  • Driver's seat adjustments may not function properly, making it difficult to achieve a comfortable driving position.
  • Inconsistent airbag deployment during tests, risking safety during a collision.
  • Difficulty in using seat memory functions if equipped, as the system may fail to recall settings.
  • Unusual noises or resistance when adjusting the seat, indicating potential wiring issues.

Possible Causes

Most common causes of B0907 (ordered by frequency):

  1. The most common cause of code B0907 is a faulty seat position sensor, which occurs in about 60% of cases. This can be due to wear and tear or a manufacturing defect.
  2. Another potential cause is damaged wiring or connectors in the seat position sensor circuit. This can happen due to repeated adjustments of the seat or exposure to moisture.
  3. A third possibility is a malfunctioning Powertrain Control Module (PCM) that fails to interpret signals correctly, though this is less common.
  4. A less common but serious cause could be a software issue within the vehicle's computer system, potentially requiring a software update from the manufacturer.
  5. In rare cases, an issue with the airbag control module may trigger this DTC, which could involve comprehensive diagnostic checks.
