How to Check the Water Temperature in Toyota Yaris?
1 Answers
Toyota Yaris is not equipped with a water temperature gauge, only a water temperature warning light. When the temperature is too high, a red warning light will illuminate on the dashboard to alert the driver. Below is relevant information about the water temperature gauge: Method to Check the Water Temperature Gauge: When inspecting the electromagnetic temperature sensor and water temperature indicator, you can disconnect the wiring on the sensor and measure the resistance between the sensor input and ground. If the resistance of the thermistor at room temperature is around 100Ω, it indicates the sensor is in good condition. Alternatively, use a resistor with a value of 80-100Ω to replace the sensor and directly ground it. When the power is turned on, if the needle of the water temperature indicator points between 60-70, it indicates the water temperature indicator is functioning properly. Function of the Water Temperature Gauge: It is used to indicate the temperature of the coolant inside the engine and serves as an important indicator of whether the engine's cooling system is operating normally.
