ESC in a car refers to the Electronic Stability Control system, with its switch located on the center console. Its function is to monitor the vehicle's driving state and prevent the car from deviating from the ideal trajectory during emergency obstacle avoidance or when understeer or oversteer occurs during turns. The working principle of the vehicle stability system is: it judges the driving state based on sensor signals and uses a control unit for precise calculations. When rotation, understeer, or oversteer occurs, it individually controls each wheel to enhance vehicle stability. Reasons for ESC system failure include: 1. ABS pump malfunction; 2. Throttle body contamination; 3. Faulty or dirty speed sensor causing incorrect signal output leading to the light illumination.

What Causes Engine Shaking After Throttle Body Cleaning?

The causes of engine shaking after throttle body cleaning include severe engine carbon buildup, ignition system issues, unstable fuel pressure, and aging engine components. If experiencing idle shaking, the owner can first perform an engine cleaning, replace spark plugs, and check the fuel supply pressure. Throttle body cleaning is one of the regular maintenance tasks required for engines. For direct injection engines, the throttle body should be cleaned every 20,000 kilometers, while for port fuel injection engines, it should be cleaned every 40,000 kilometers. Severe carbon buildup in the throttle body can affect the vehicle's idle, fuel consumption, power, and air conditioning functions.

What is the size of car tire bolts?

Car tire bolts come in four sizes: 17mm, 19mm, 21mm, and 22mm. The size varies depending on the tire model and vehicle type. Owners should check their vehicle's specifications for exact sizes. For example, Toyota models typically use 21mm bolts, Honda models use 19mm, Volkswagen models use 17mm, while Mercedes-Benz passenger cars use 17mm and larger vehicles use 19mm. Some cars have 5 fixing bolts, while others have 4. SUVs generally have 5 fixing bolts. The number of bolts is related to the vehicle's weight and load capacity. Heavier vehicles require fewer bolts to distribute the force adequately, necessitating thicker bolts to meet strength requirements. However, four thick bolts are less aesthetically pleasing compared to five slightly thinner bolts.

What does it mean when the car's eco light is on?

When the car's eco light is on, it indicates that the vehicle is operating in fuel-saving mode. The eco mode controls fuel consumption by regulating the throttle and fuel injector.

The active mode usually comes with a dedicated button, allowing the driver to manually enable or disable it. The passive mode does not have a specific button; it serves as a reminder to save fuel.
