How to Determine if the Water Temperature Sensor is Damaged?
1 Answers
Methods to determine if the water temperature sensor is damaged include: 1. The water temperature gauge needle directly points to the highest position; 2. The water temperature gauge needle does not move; 3. Use a digital resistance simulator to simulate water temperature and compare it with the actual situation; 4. Use an infrared thermometer to measure the actual temperature of the water temperature sensor and compare it with the water temperature gauge. The functions of the water temperature sensor are: 1. Through internal resistance changes, it achieves the effect of altering the current passing through the sensor's resistance to drive changes in the water temperature gauge, indirectly reflecting the engine's operating temperature; 2. Provides an analog signal of temperature changes to the engine control unit.
