Sunload Sensor (Solar Sensor)
The sunload sensor measures sunlight hitting the car so the climate control can increase cooling when the sun shines in.
What is Sunload Sensor (Solar Sensor)?
It sits on top of the dashboard near the windscreen and is often combined with the light sensor for automatic headlights. Some versions measure from which side the sun shines to adjust each zone separately. It is a photodiode that produces a signal proportional to light intensity.
How it works
When strong sunlight is detected, the system lowers the outlet temperature or raises the fan speed before the cabin heats up.
Why it matters for your car
A faulty or covered sensor can make the system react slowly to changing sunlight. Do not cover the sensor with items or dashboard mats.
