What Causes Power Loss and Jerking When Accelerating with AC On in a Car?

What Causes the Steering Wheel to Become Heavier in a Car?

There are several reasons why a car's steering wheel may become heavier: 1. Insufficient power steering fluid: Power steering fluid is a medium used in the car's power steering pump to transmit steering force and provide cushioning. It needs to be replaced regularly, and leaks should be checked. When the fluid is insufficient, the steering wheel may feel heavy and stiff. 2. Low tire pressure: Low tire pressure increases the contact area between the tires and the road, leading to greater friction and making steering more difficult, resulting in a heavy steering wheel, which is unsafe for driving. 3. Toe-in issues: Toe-in can also affect the car's steering. Toe-in helps the steering wheels automatically return to the center, ensuring stable straight-line driving. Problems in this area can also cause a heavy steering wheel. 4. Steering gear or power steering pump failure: The steering gear and power steering pump are crucial components affecting steering. Any malfunction in these parts can make steering difficult. Issues such as universal joints, chassis suspension stabilizer bars, or plain bearings should not be overlooked. 5. Overly tight bearing fit: If the rolling or sliding bearings in the steering system are too tightly fitted, it can lead to poor lubrication and cause sticking or resistance.

How Many Chances Are There for a Driving Test Retake?

Here is the relevant information about driving test retakes: 1. Subject 1 is a theoretical test, and Subject 3 is about common knowledge of safe driving. There is no limit to the number of retakes for these subjects. If you fail initially, you can schedule another test until you pass. However, Subject 2 has a retake limit; you cannot schedule more than five tests, with each scheduling offering two attempts. If you still fail on the fifth scheduled test, all previous results will be invalidated. 2. For each failed subject, there is one immediate retake opportunity. If a candidate does not attend the retake or fails the retake, they can schedule another test later. However, not all subjects can be rescheduled immediately. Candidates who fail Subjects 2 and 3 must wait ten days before scheduling the next test. The total duration for obtaining a driver's license is three years. If this period is exceeded, all results become invalid, and the candidate must start over from Subject 1. 3. For Subjects 2 and 3, there are five official test opportunities and five retake opportunities. Each test session includes one official test and one retake opportunity. If both attempts fail, the candidate must reschedule, up to five times in total. Passing any one of these opportunities counts as a pass. If all ten attempts fail, the results of other previously passed subjects will be invalidated.

Where is the engine sensor located?

The engine speed sensor is generally mounted on the flywheel. Below is an introduction to the classification of engine sensors: 1. Crankshaft position sensor: 1. Function: It is the most important sensor in the computer-controlled ignition system. Its role is to detect top dead center signals, engine speed signals, and crankshaft angle signals, and input them into the computer to control the ignition sequence of the cylinders and issue the optimal ignition timing commands. 2. Types: Electromagnetic induction type, Hall effect type, photoelectric effect type. 2. Camshaft position sensor: Function: Collects the position signal of the valve camshaft and inputs it into the ECU, so that the ECU can identify the top dead center of the compression stroke of cylinder 1, that is, provide the cylinder identification signal (the cylinder identification signal is the sole basis for the ECU to perform fuel injection timing and sequential control), thereby enabling sequential fuel injection control, ignition timing control, and knock control. It is also used to identify the first ignition timing at this moment.

How to Distinguish Between China 5 and China 6?

Here are the methods to distinguish between China 5 and China 6: 1. The China 5 emission standard is marked with "V", while the China 6 emission standard is marked with "Ⅵ", both using Roman numerals. 2. When purchasing a new car, the salesperson will provide a vehicle acceptance form, which includes the model, color, emission standard, engine number, and chassis number. 3. For used cars, you can query the vehicle's complete model number on the environmental protection website. The steps to query the emission standard for China 5 and China 6 vehicles are as follows: 1. First, you need to know the complete model number of the vehicle you want to query, which is usually labeled on the vehicle's nameplate. 2. Visit the Motor Vehicle Environmental Protection website, enter the fuzzy condition (complete model number) in the input box, input the correct verification code, and click "Query" to find relevant information about the vehicle, including the emission standard. The vehicle nameplate is usually located below the passenger side door. Other places where you might find the relevant label with the complete model number include the lower left corner of the front windshield, the driver's door pillar, the left side of the dashboard, the engine compartment, the adhesive strip on the side door, the door frame base, and inside the glove box.

Who is at fault when a lane-cutting vehicle gets hit?

Determining liability when a lane-cutting vehicle gets hit depends on specific circumstances, as explained below: 1. Lane-changing vehicles must not obstruct vehicles traveling normally in their lane. If a traffic accident occurs, the lane-changing vehicle will bear all or primary responsibility for the accident. Whether it's straddling lane markings or making an emergency lane change, regardless of whether the line is dashed or solid, the lane-changing vehicle will be primarily or fully at fault. 2. If the rear vehicle intentionally hits the lane-cutting vehicle, the situation is different. Intentional collision constitutes a traffic offense and will be entirely the rear vehicle's responsibility. However, in most cases, it's difficult to determine from driving behavior or surveillance footage alone whether the rear driver acted intentionally. Substantial evidence is required to prove intentional collision by the rear vehicle. 3. If the lane-cutting vehicle has completed its lane change and the rear vehicle then hits it, this will most likely be classified as a rear-end collision. If the rear vehicle is proven to have intentionally caused the collision, not only will it bear full responsibility for the accident, but insurance companies will also refuse to cover the damages.

Can Brake Fluid Be Topped Up If It's Low?

Brake fluid cannot be directly topped up. The correct method for replacing brake fluid is as follows: 1. First, park the car securely, then open the hood and the brake fluid reservoir cap before extracting the old fluid. 2. After lifting the car, locate the bleeder screw near the brake caliper, loosen it to allow fluid to drain, and use a vacuum pump to extract the old fluid while simultaneously pouring new brake fluid into the reservoir under the hood. Continue this process for about three minutes before tightening the screw. 3. Once all the old fluid has been extracted, have someone press the brake pedal five or six times and hold it down while you slightly loosen the bleeder screw to allow air and fluid to escape. Release the pedal and repeat this process for all four wheels, cycling through three times each.
