Corolla spark plugs should be replaced every 30,000 kilometers or 18 months. The spark plug is part of the ignition system, and its main function is to introduce the high-voltage electricity from the ignition coil into the engine cylinder, generating a spark between the electrodes of the spark plug to ignite the air-fuel mixture, thereby enabling the engine to perform work. The Corolla, once known as the 'Corolla' in Chinese, is a brand under Toyota Motor Corporation. In terms of body dimensions, the Corolla measures 4630mm in length, 1775mm in width, and 1480mm in height, with a wheelbase of 2700mm. Externally, the Corolla is characterized by a balanced and dignified appearance, with no particularly outstanding highlights, making it well-suited for family use. The interior of the Corolla features an overall minimalist style, with a conventional dashboard design, spacious and comfortable seats, effective air conditioning, and good craftsmanship.

What to Do If the Subject 1 Exam Cannot Be Canceled?

If the Subject 1 exam appointment cannot be canceled, you will have to attend the exam. If the driving school made the appointment, you can request cancellation through your driving instructor. If you made the appointment online yourself, there should be a cancellation button on the appointment website—follow the instructions provided. Applicants who cannot attend the exam at the scheduled time must apply to cancel the appointment at least one day in advance. Below are some important notes for the Subject 1 exam: 1. Arrive Early: Regardless of the driving school, try to arrive about half an hour early. Since most candidates are taking the Subject 1 exam for the first time, arriving early allows the driving school staff to distribute admission tickets and explain exam techniques in detail. 2. Bring Required Documents: Carry your ID card, as it will be scanned along with the admission ticket to assign your seat before entering the exam hall. 3. Keep Your Face in the Frame: Pay attention to the video feed in the top-left corner of the screen, ensuring your face remains fully visible throughout the exam. Both your answers and video feed will be uploaded together, and an improperly positioned face may invalidate your results.

Why Does the Air Pressure Drop Too Quickly When a Truck Brakes?

The reason why the air pressure drops too quickly when a truck brakes is due to air leakage in the brake master cylinder. This is usually caused by infrequent exhaust of the air reservoir, leading to dirt accumulation inside the air reservoir. When braking, the dirt is pushed into the master cylinder, resulting in air leakage. Below are detailed explanations: 1. Solution: If the vehicle's air reservoir cannot store sufficient compressed air, the air supply from the brake valve is insufficient, there is a leak in the brake valve pipeline, or the air passage is blocked, it can cause the air pressure to disappear too quickly during braking. If any of these conditions occur, the vehicle should be sent to an after-sales service or repair shop for maintenance. After repair, the vehicle can be used normally. 2. Air Brake: An air brake is a type of braking system. In automobiles, a series of specialized devices that apply a certain force to specific parts of the vehicle to achieve a certain degree of forced braking are collectively referred to as the braking system.

Why Does a New Energy Vehicle Suddenly Lose Power?

Possible reasons are as follows: poor contact between the battery power output plug and socket; failure of the speed control handle; power signal system failure. Below are detailed explanations of the specific reasons: 1. Poor contact between the battery power output plug and socket: Generally, it may be caused by wear and oxidation over time, leading to poor internal circuit contact. 2. Failure of the speed control handle: Usually, it's due to poor contact among the three wires inside the speed control handle, typically red, gray, and black, or red, green, and black, with the gray or green wire being the output signal line of the handle. It's best to cut off the middle connector of the speed control handle's connecting wires, reconnect them according to the color difference, and then wrap them securely with insulating tape for foolproof safety. 3. Power signal system failure: If the electric vehicle is highly intelligent, it may also experience power loss. This is mainly manifested in damage to the ignition lock or poor contact between the controller and the ignition lock signal line. The simplest solution is to activate the keyless function.

Why does the throttle not respond when the air conditioner is turned on?

Here is the relevant introduction to the throttle not responding when the air conditioner is turned on: 1. Poor sealing: Incorrect valve timing, such as intake and exhaust valves not sealing tightly. 2. Fuel pump failure: The fuel pump may operate poorly, short-circuit, or burn out due to internal or wiring issues, leading to insufficient or interrupted fuel supply. 3. Blocked intake system: Components like the air filter or air flow meter may prevent proper mixing of air and fuel. 4. Internal engine issues: Improper maintenance, premature or abnormal wear, or faults in cylinder pressure, among other potential causes.
