B0183:05 Code - Solar Load Sensor Circuit High Voltage/Open
Quick Answer
The ambient light/sunload sensor integrates the sunload sensor and passenger compartment temperature sensor into a single assembly. Common causes include Faulty Solar Load Sensor, Solar Load Sensor harness is open or shorted, Solar Load Sensor circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Code B0183:05 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 interior temperature to increase. The HVAC system compensates for the increased temperature by diverting additional cool air into the vehicle.
The Diagnostic Trouble Code (DTC) will be set when the input signal is out of range. The voltage is greater than 4.9 V.
What are the Possible Causes of the DTC B0183:05?
- Faulty Solar Load Sensor
- Solar Load Sensor harness is open or shorted
- Solar Load Sensor circuit poor electrical connection
- Faulty Heating, Ventilation, and Air Conditioning (HVAC) Control Module
How to Fix the DTC B0183:05?
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.
