Code B2116 GMC Description

The B2116 diagnostic trouble code (DTC) is specific to GMC vehicles and indicates an issue with the power seat position sensor voltage. This sensor is critical for determining the position of the power seat in relation to the vehicle's interior. It communicates with the vehicle's body control module (BCM) to ensure that the seat is positioned correctly for optimal comfort and safety. When the BCM detects a voltage reading from the power seat position sensor that is outside the expected range, it triggers the B2116 code.

  5. The seat may move erratically or not hold its position after adjustment.

How to Fix B2116 GMC

  1. Diagnostic Testing: Begin by using an OBD-II scanner to confirm the B2116 code and check for any additional codes that may provide further insight into the issue.
  2. Visual Inspection: Inspect the wiring and connectors associated with the power seat position sensor for any signs of damage, corrosion, or loose connections.
  3. Sensor Testing: Test the power seat position sensor with a multimeter to ensure it is functioning within the specified voltage range. Replace the sensor if it is found to be faulty.
  4. Repair Wiring: If damaged wiring is identified, repair or replace the affected sections to restore proper electrical flow.
  5. Reprogramming (if necessary): After repairs, it may be necessary to clear the DTC and reprogram the BCM to recognize the new sensor or wiring configuration.

Cost to Fix B2116 GMC

** The typical repair costs for addressing a B2116 code can vary widely based on the specific issue identified during diagnosis. On average, the cost may range from $150 to $600. This estimate includes parts such as a new power seat position sensor (which can cost between $50 and $200) and labor charges. Labor rates generally range from $80 to $150 per hour, depending on the shop's location, the vehicle's make and model, and the complexity of the repair.
