|What Does the B0183 Buick Code Mean?

The ambient light/sunload sensor integrates the sunload sensor and passenger compartment temperature sensor into a single assembly.
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 interior temperature to increase. The HVAC system compensates for the increased temperature by diverting additional cool air into the vehicle.
