Where is the Sunny Water Temperature Sensor Located?
2 Answers
The Sunny water temperature sensor is located on the water jacket of the engine block or cylinder head, where it directly contacts the coolant to measure the engine's coolant temperature. The Sunny water temperature sensor is an electronic component in the automotive circuit, and if it fails, it cannot be repaired—only replaced. Symptoms of a faulty Sunny water temperature sensor include: 1. The temperature gauge needle does not move or points to the highest position; 2. When starting a cold engine, it still displays the temperature signal of a hot engine, causing the ECU to fail to receive the signal for a rich air-fuel mixture and only provide a lean mixture to the engine; 3. Increased fuel consumption and unstable idle speed; 4. Difficulty in acceleration, with the engine speed not increasing even when the throttle is fully depressed.
I have a habit of tinkering with these small car components myself. The sunlight sensor is usually installed on top of the dashboard in most vehicle models, positioned right opposite the central area of the windshield. This allows it to directly capture sunlight intensity and assist the air conditioning in automatically adjusting temperature and airflow modes. The placement is practically designed: some cars hide it inside plastic covers, requiring dashboard removal to access; my car once had it clogged with dust, making the AC blow erratically and leaving me sweating during winter drives. I recommend gently wiping its surface with a soft cloth to prevent dust buildup that may interfere with functionality. If the AC malfunctions, first check if the sensor's wiring is loose; its proximity to the windshield makes it susceptible to fog or insect interference. Overall, this location cleverly combines space utilization with precise sensing, and simple maintenance can save significant repair hassles. Also, avoid strong chemicals when cleaning to prevent coating damage – keeping it clean ensures more responsive system performance.
