Common faults of the coolant temperature sensor include: 1. Changes in thermistor performance; 2. Poor line contact or open circuit; 3. No coolant temperature signal or inaccurate signal from the ECU; 4. The cooling fan does not rotate; 5. The temperature gauge does not indicate. Methods to determine if the coolant temperature sensor is damaged are: 1. Use a digital resistance simulator to simulate the coolant temperature and compare it with the actual situation; 2. Use an infrared thermometer to test the actual temperature of the coolant sensor and compare it with the temperature gauge. The functions of the coolant temperature sensor are: 1. To drive the change of the temperature gauge by altering the current passing through the sensor via changes in internal resistance, indirectly reflecting the engine's operating temperature; 2. To provide the engine control unit with an analog signal of temperature changes.

What are the causes of oil leakage in a Porsche Cayman engine?

Porsche Cayman engine oil leakage is caused by: 1. Uneven tightening torque of fastening nuts, stripped threads, or loose and falling off, leading to operational failure, poor product quality, or substandard materials and workmanship; 2. Excessive addition of lubricating oil, high oil level, incorrect oil type, improper installation configuration, unclean mating surfaces, damaged gaskets, displacement, or failure to follow installation procedures; 3. Blockage of the vent plug or check valve, causing a pressure difference inside and outside the housing, resulting in oil leakage at weak sealing points; 4.
