Final answer:
If the aspirator tube is plugged, the reading for the sun load sensor will be off.
Step-by-step explanation:
The sun load sensor is used to measure the intensity of sunlight. If the aspirator tube, which is responsible for providing air to the sensor, is plugged, it can lead to inaccurate readings. When the aspirator tube is blocked, the sensor may not be able to accurately measure the sunlight, resulting in an off reading.
For example, if the tube is clogged with dirt or any other obstruction, it may restrict or completely block the airflow to the sensor. This will prevent the sensor from receiving the required amount of air, affecting its measurement of the sun load.
