|How do I fix the B0183 code?Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
|B0183 code tech notesB0183 02: Solar Load Sensor Circuit Short to Ground
B0183 05: Solar Load Sensor Circuit High Voltage/Open
|Cost of diagnosing the B0183 code
Labor: 1.0The cost of diagnosing the B0183 code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
|What are B0183 code possible symptoms?
- Engine Light ON (or Service Engine Soon Warning Light)
|B0183 code descriptionThe ambient light/sunload sensor integrates the sunload sensor and passenger compartment temperature sensor. This sensor assembly provides information about the sun heat intensity and passenger Compartment Temperature.
The solar sensor is connected to ground and to the 5 V stabilized voltage supply through the Heating, Ventilation, and Air Conditioning (HVAC) Control Module. As the sunload increases, the sensor signal voltage also increases and vice versa. The signal varies between 1.4-4.5 V and is provided to the HVAC control module.
The passenger compartment temperature sensor is a negative temperature co-efficient thermistor. A signal and low reference circuit enables 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 vehicles interior temperature to increase. The HVAC system compensates for the increased temperature by diverting additional cool air into the vehicle.
