Where is the outdoor temperature sensor located on the Buick Excelle?
1 Answers
Buick Excelle's outdoor temperature sensor is located at the front bumper grille. This sensor is a component of the automatic air conditioning system, primarily responsible for providing the ECU with external temperature signals. The ECU compares this signal with the interior temperature signal to determine the cabin temperature, meeting the comfort needs of the occupants. The sensor consists of three main parts: 1. Sensing element: Directly detects (or responds to) the measured variable, converting it into a non-electrical quantity or other form of energy with a definite relationship to the measured parameter. 2. Conversion element: Transforms the aforementioned non-electrical quantity into an electrical parameter. 3. Measurement circuit: Processes the electrical parameter input from the conversion element into measurable electrical quantities such as voltage, current, or frequency for display, recording, control, and processing purposes.
