Question

Quizplus · Accepted Answer

A disconnected in-car temperature sensor aspirator tube can cause the temperature to fluctuate because the automatic temperature control system relies on accurate temperature readings from inside the vehicle to adjust the heating and cooling settings. If the tube is disconnected, the system may not get accurate readings, leading to inconsistent temperature control.
