Why does the temperature warning light come on when the engine temperature is normal?

What Causes the Engine Warning Light to Illuminate and Lack of Power When Accelerating?

When the engine warning light on the car dashboard illuminates and there is a lack of power when accelerating, the possible reasons are as follows: 1. Oxygen sensor malfunction: To ensure complete combustion of the air-fuel mixture, enhance engine power, and reduce harmful emissions, the ECU uses the oxygen sensor to detect oxygen concentration in the exhaust and adjust the fuel injection accordingly, maintaining the optimal air-fuel ratio. If the oxygen sensor fails and the ECU cannot receive oxygen concentration data, the engine warning light will turn on, accompanied by a lack of power during acceleration. 2. Poor fuel quality: Low-quality gasoline leads to incomplete combustion of the air-fuel mixture, triggering the engine warning light and causing a lack of power during acceleration.

How to Remove New Car Odor?

Here is the relevant introduction on how to remove new car odor: 1. Place plants: Place some air-purifying plants in the car to maintain effective circulation of odors inside the vehicle. You can also frequently carry fruits that have odor-removing effects, such as pineapples, oranges, etc. 2. Remove plastic film promptly: New cars usually come with plastic protective films on seats and other interior components to maintain the newness of the interior. These protective films should be removed promptly as they are also a source of odor. The films block the natural circulation of the seat's own smell, preventing effective odor removal. 3. Air circulation: Ensure good air circulation inside the car by opening the windows. When necessary, you can open the doors to allow air exchange between the interior and exterior. While driving, try opening the windows for ventilation.

How Many Types of Transmission Fluid Are There?

Transmission fluid is a mechanical or hydraulic device used for mechanical power conversion. Here is an introduction to how many types of transmission fluid there are: 1. Introduction: In automobiles, the transmission is commonly referred to as the "gearbox"; in industrial machinery, it is often called a "speed changer," which is a mechanical or hydraulic device for mechanical power conversion. 2. Performance in Use: Currently, the better method for changing transmission fluid is dynamic fluid replacement. This involves using specialized transmission cleaning equipment to fully circulate the old fluid during transmission operation, thoroughly draining it before adding new transmission fluid. This method achieves a fluid replacement rate of over 90%, ensuring excellent results.

How to Power On the Car with One-Key Start?

With the smart key inside the car, pressing the one-key start button will power on the vehicle. Here is some related information about one-key start: 1. Definition: The one-key start device is part of a smart car, serving as a button mechanism to simplify the starting process and also to turn off the engine. This device can be retrofitted either at the original key lock position or as an independent panel. 2. Precautions: The starting method is software-based one-key start. There are three main points to note when installing a one-key start system (the wiring of the plug under the ignition switch, the position of the button, and the handling of the steering lock), and it comes with multiple functions.

What is the Function of a Knock Sensor?

The functions of a knock sensor are: 1. To measure engine vibration and adjust the ignition timing when engine knocking occurs; 2. It serves as an AC signal generator to detect the speed and position of the rotating shaft. A knock sensor consists of: a magnetic core, permanent magnet, and induction coil. The working principle of a knock sensor is: when vibration or knocking occurs, it generates a voltage peak. The greater the knocking or vibration, the higher the peak voltage produced by the knock sensor. A certain high frequency indicates knocking or vibration. The knock sensor can measure frequencies in the range of 5 to 15 kHz. When the control unit receives these frequencies, the computer recalibrates the ignition timing to prevent further knocking.

Consequences of a Stuck Turbo Wastegate?

About the consequences of a stuck turbo wastegate, the introduction is as follows: 1. Engine performance. The engine exhibits sluggish response to throttle input at low to medium speeds, and knocking may occur during medium to high-speed acceleration, affecting the engine's power output. If diagnosed with a specialized diagnostic tool, the engine system will display fault codes indicating issues with the turbocharging system. 2. Symptoms of wastegate damage. This can lead to boost pressure leakage, reducing the compressor's efficiency, resulting in engine power loss, difficulty accelerating, or black smoke emissions. 3. Basic function of the wastegate. When the engine's intake pressure exceeds a certain threshold, the mechanism acts on the turbine side to divert exhaust gases, thereby reducing the exhaust flow through the turbine.
