Code B1261 GMC Description
The B1261 GMC code indicates a problem with the solar radiation sensor circuit, specifically a short to ground. The solar radiation sensor is responsible for measuring the intensity of sunlight and providing this information to the vehicle's climate control system. This data is used to adjust the temperature inside the vehicle and control the operation of features like automatic headlights and sunroofs.
Common Causes of B1261 GMC
- Damaged wiring in the solar radiation sensor circuit.
- Faulty solar radiation sensor.
- Poor connection between the sensor and the vehicle's electrical system.
- Corrosion in the sensor circuit.
- Electrical issues in the vehicle's wiring system.
Symptoms of B1261 GMC
- Incorrect temperature readings on the climate control system.
- Automatic headlights not adjusting to changing light conditions.
- Sunroof not opening or closing automatically.
- Inconsistent performance of the climate control system.
- Decreased fuel efficiency.
How to Fix B1261 GMC
- Begin by locating the solar radiation sensor in the vehicle. This sensor is typically located on the dashboard or near the windshield.
- Inspect the wiring connected to the sensor for any signs of damage or corrosion. Repair or replace any damaged wiring.
- Test the sensor itself to determine if it is functioning correctly. Replace the sensor if it is found to be faulty.
- Check the connection between the sensor and the vehicle's electrical system to ensure it is secure and free of corrosion.
- Clear the diagnostic trouble code from the vehicle's system using an OBD-II scanner after completing the repair.
Cost to Fix B1261 GMC
The typical repair costs for addressing a solar radiation sensor circuit short to ground can range from $150 to $300, including parts and labor.
