Fault phenomenon
    A Santana 2000GLi-type car at high temperatures, the engine suddenly turn off, after cooling, the engine can start smoothly, the temperature rises, the engine and turn off.
    Troubleshooting and troubleshooting
    This type of failure is generally a problem with the cooling system. But the coolant temperature alarm after the engine does not warm up, indicating that the cooling system is not "boil" phenomenon, the electric fan is running normally, high and low block wind speed are; expansion tank cooling liquid level is also within the scale range.
    Use the fault diagnosis instrument V.A.G1551 to read the information in the self-diagnosis system, the fault code is displayed as "00522", for the coolant temperature sensor failure. The use of digital multimeter or ECU detector on the cooling temperature sensor and its line to detect the resistance value of ∞, indicating that the coolant inside the wet sensor damage. Replace coolant temperature sensor, engine troubleshooting.
    The coolant temperature sensor is located near the thermostat shell and inputs the fuel injection and ignition correction signals to the ECU. When the coolant temperature sensor failure, ECU into the open state, the hot state due to the mixture is too strong engine flameout, the engine shut down after cooling, to be excessive gasoline after the normal operation of volatile.
