p1545 trouble code is caused by throttle carbon deposit being too dirty, throttle not fully closing, throttle position actuator or its circuit or connector failure, etc. The solutions include cleaning the throttle or directly replacing it with a new one. It is recommended to go to a 4S shop for inspection and repair. More relevant information is as follows: 1. The throttle, commonly known as the accelerator, is a controllable valve used to regulate the engine's air intake. 2. The Throttle Position (TP) sensor's function is to send the throttle opening degree to the Electronic Control Unit (ECU) in the form of an electrical signal, serving as one of the basic parameters for controlling engine fuel injection.

Why Can't You Walk Around the Car Clockwise?

Because China implements right-hand traffic, vehicles are generally parked on the right side of the road. The driver needs to enter the driver's seat from the left side, so conducting a counterclockwise inspection from the left front door ensures the driver can see oncoming traffic and road conditions from behind, which is safer. Below are some important points to note for the Subject 3 driving test: 1. Before starting the test: Walk around the car counterclockwise to check the vehicle's condition. 2. After getting in the car: Adjust the seat position, adjust the rearview mirror angle, and fasten the seatbelt. Only after completing these steps can the test begin. 3. During all test items: Listen to the voice prompts and avoid acting before the prompts. Pay special attention to the school and bus stop sections, where there are no voice reminders. You must perform a deceleration and braking action within 30 meters, but avoid braking too early. 4. After completing the roadside parking: Do not rush to exit the vehicle. Open the door, then close it, and wait for the voice announcement of your score before getting out. Don’t forget to close the door after exiting.

Where is the tail light switch located?

Car tail light switches are typically located on the lighting control lever or rotary knob. Generally, when the parking lights are turned on, the tail lights will also activate simultaneously. Tail lights serve to alert following vehicles of the presence of your car during nighttime driving and indicate the positional relationship between the two vehicles, hence they are installed on both sides of the rear. Characteristics of car tail lights: They possess sufficient luminous intensity to ensure the signals are clearly distinguishable by other drivers or pedestrians even in bright daylight. The light emitted by tail lights during nighttime driving does not cause glare or discomfort to other drivers or pedestrians. How to turn on car tail lights: Start the vehicle's electrical system and activate the headlight switch. Whether high beams or low beams are engaged, the tail lights will automatically illuminate with the headlights. During nighttime driving, tail lights notify following vehicles of your presence and display the spatial relationship between vehicles. Other lighting at vehicle rear: Rear lighting includes red parking lights, red brake lights, red high-mounted stop lights, yellow turn signals, white reverse lights, and red fog lights. All these constitute the rear lighting system of motor vehicles, serving to enhance safety warnings.

What are the five operations in driving test subject two?

Subject two of the driving test includes five operations: hill start, parallel parking, right-angle turn, S-curve, and reverse parking. Below are specific techniques for driving test subject two: 1. Slow speed: Maintaining a slow speed is the fundamental rule for practicing subject two. Ensure the vehicle doesn't stall while keeping the speed as slow as possible, allowing ample time to adjust each operation. 2. Adjust mirrors properly: After getting in the car, always adjust the mirrors correctly, which is especially important for reverse parking and parallel parking. 3. Master the three-point alignment method: The three points are the driver's eyes, reference points on the car, and reference points on the ground. During subject two operations, it's crucial to accurately locate and observe these points for precise execution. 4. Pay attention to the four corners of the car: The front corner during reverse parking tends to scrape the outer line, while the rear corner may scrape the side lines of the parking space; the front corner during S-curve driving is prone to crossing the line; the front corner during right-angle turns is likely to cross the line; the front corner during parallel parking may scrape the outer line or the left front corner of the parking space, and the right rear corner may scrape the right parking space line. Therefore, always be mindful of the four corners and the outer boundary lines.
