Code B0163 2015 GMC Sierra Description
The solar sensor is connected to a low reference and a 5 V biased (pull-up) signal circuit voltage from the Heating, Ventilation, and Air Conditioning (HVAC) Control Module. As the sunload increases, the sensor signal voltage decreases. The signal varies between 0.1 - 4.9 V and is provided to the HVAC control module.
The passenger compartment temperature sensor is a negative temperature coefficient thermistor. A signal and low reference circuit enable the sensor to operate. As the air temperature increases, the sensor resistance decreases. The sensor signal varies between 0 - 5 V.
Bright or high-intensity light causes the vehicle's interior temperature to increase. The HVAC system compensates for the increased temperature by diverting additional cool air into the vehicle.
What are the Possible Causes of the DTC B0163 2015 GMC Sierra?
- Faulty Ambient Light/Sunload Sensor
- Ambient Light/Sunload Sensor harness is open or shorted
- Ambient Light/Sunload Sensor circuit poor electrical connection
- Faulty Heating, Ventilation, and Air Conditioning (HVAC) Control Module
How to Fix the DTC B0163 2015 GMC Sierra?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
