oil temp gauge not working

• 2022-02-24

The oil temperature is the oil temperature and the water temperature is the coolant temperature. Generally, there is only one of the two on the instrument of a car. The engine temperature is transmitted first to the oil and then to the coolant.The first level of engine cooling is oil, and if the engine contacts the inner wall of the cylinder, the oil can more accurately reflect the temperature of the engine. Because the best working temperature of the engine is 80 degrees, and the best working temperature of the oil is 100 degrees. Although the difference between the two is 20 degrees, this intermediate temperature will not affect anything, so since the oil can better reflect the temperature of the engine.Oil temp gauge not working its because the vehicle temperature sensor breaks down, the engine will overheat, and the yellow water temperature fault light will appear on the instrument panel and meter to remind the driver to detect it. It is recommended to repair it immediately to avoid potential safety hazards in the process of using the vehicle.

Temperature sensor refers to a sensor that can sense the temperature and convert it into an available output signal. Temperature sensor is the core part of temperature measuring instrument, which has a wide variety.

After the water temperature sensor is damaged, the indicator light on the instrument panel will flash or be on constantly to warn. Since the water temperature sensor is broken, there will be an error between the temperature displayed by the water temperature gauge and the actual temperature (too high, too low or no temperature). If there is no history of excessive engine temperature in the past (the water temperature has been normal in the past) and the water tank is not short of water (or coolant), there will be no problem for the engine to work in a short time. At least you can drive the car to the 4S store or repair shop. The replacement of the water temperature sensor is very fast. It is recommended to replace it in time. (the water temperature sensor is not a thermostat, which will not make it difficult to start).

If the intake air temperature sensor and intake air temperature sensor are faulty or damaged, the engine will not be able to accurately calculate the fuel injection amount, resulting in too thick or too thin mixture, and the vehicle will have difficulties in starting, unstable idle speed, jitter or black smoke from the exhaust pipe, which will affect the performance of the engine.
