Code B1B92 Description

The diagnostic trouble code (DTC) B1B92 refers to a malfunction within the passenger seat track position sensor circuit. This sensor is crucial for determining the position of the passenger seat, which is integral to the proper functioning of various vehicle systems, including airbag deployment and seatbelt tensioning. When the vehicle's onboard computer detects an inconsistency or failure in the sensor's performance, it triggers this code, indicating that the sensor is not providing accurate data or is malfunctioning.

Common Causes of B1B92

  1. Faulty Seat Track Position Sensor: The sensor itself may be defective or damaged, leading to inaccurate readings.
  2. Wiring Issues: Damaged or corroded wiring in the sensor circuit can disrupt communication between the sensor and the vehicle's computer.
  3. Connector Problems: Loose, corroded, or damaged connectors can prevent proper electrical contact, resulting in circuit performance issues.
  4. Mechanical Obstructions: Debris or foreign objects lodged in the seat track can impede the movement of the seat and affect sensor performance.
  5. Software Glitches: Occasionally, a software issue within the vehicle's onboard computer may misinterpret sensor data, triggering the code.

Symptoms of B1B92

  1. Airbag Warning Light: The airbag warning light may illuminate on the dashboard, indicating a potential issue with the airbag system.
  2. Inconsistent Seat Positioning: The passenger seat may not adjust correctly or may revert to a previous position unexpectedly.
  3. Erratic Sensor Readings: The vehicle's onboard diagnostics may display erratic or incorrect readings related to the passenger seat position.
  4. Comfort Features Malfunction: Features such as heated seats or memory settings may fail to operate as intended.
  5. Increased Resistance in Seat Adjustment: The seat may feel stiff or difficult to adjust, indicating a potential mechanical issue with the track or sensor.

How to Fix B1B92

  1. Diagnostic Scan: Begin with a thorough diagnostic scan to confirm the presence of the B1B92 code and check for any additional codes that may provide further insight.
  2. Visual Inspection: Conduct a visual inspection of the passenger seat track position sensor, wiring, and connectors for signs of damage, corrosion, or disconnection.
  3. Test the Sensor: Use a multimeter to test the sensor's resistance and voltage output to determine if it is functioning within specifications.
  4. Repair or Replace Components: Depending on the findings, repair any damaged wiring or connectors, or replace the faulty seat track position sensor as needed.
  5. Clear Codes and Test Drive: After repairs, clear the diagnostic codes and perform a test drive to ensure that the issue has been resolved and that the seat adjustment and airbag systems are functioning correctly.

Cost to Fix B1B92

** The typical repair costs for addressing the B1B92 code can vary widely based on several factors, including the make and model of the vehicle, the specific parts needed, and labor rates in the area. On average, the cost for parts (such as a new seat track position sensor) can range from $50 to $200. Labor costs can vary, with most auto repair shops charging between $80 and $150 per hour. The total repair cost, including parts and labor, could range from $150 to $500.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

  • Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
  • Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
  • Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
  • Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
