Excessively low fuel rail system pressure can cause vehicle body shaking. Below are additional details: 1. Solution: Check whether the fuel supply pressure and intake pressure sensor are normal. If the fuel pump supply pressure is abnormal or the intake pressure sensor values are incorrect or malfunctioning, it can lead to vehicle body shaking. Inspect the oil pressure and replace components if necessary. 2. Other situations: Due to mechanical wear, improper assembly, or other faults, it may cause excessively low or no oil pressure. Diesel engines generally have a pressure regulating valve that can adjust the oil pressure.

What causes slight shaking when the car is idling?

The reasons for a car shaking during idle are as follows: 1. Intake system failure: Excessive carbon buildup in the throttle body and intake manifold, clogged air filter element, leaks in the intake pipe or EGR valve, faulty intake pressure sensor. 2. Fuel system failure: Fuel supply pressure issues, faulty fuel injectors. 3. Ignition system failure: Spark plugs not firing or weak spark energy, faulty ignition module or ignition coil, malfunctioning sensors or ignition control circuit. 4. Electronic control system failure: Internal circuit damage or poor contact in the electronic control system. 5. Mechanical structure failure: Damaged or weakened piston rings, carbon buildup in piston ring grooves, carbon deposits in cylinders, bent or deformed connecting rods, incorrect timing belt installation. 6. Other reasons: Air conditioning system, automatic transmission, etc., which increase engine idle load, clogged catalytic converter, imbalance in rotating components such as the crankshaft and flywheel.

What are the dress code requirements for the Subject 3 driving test?

For the driver's license test, there are no specific clothing taboos as long as you avoid wearing bizarre outfits, slippers, or high heels.

Do I need to take an exam if my driver's license is deducted 11 points?

If your driver's license is deducted 11 points, you do not need to take an exam. Only when all 12 points are deducted will you be required to study and take an exam. If a motor vehicle driver accumulates 12 points within a scoring cycle, the traffic management department of the public security authority shall detain their motor vehicle driver's license. You can apply for 'study to reduce points' through the Traffic Management 12123 mobile app. After studying and passing the exam, you can reduce 1 point each time, with a maximum reduction of 6 points within a scoring cycle. In other words, your driver's license can gain 6 points at this time. The motor vehicle driver shall, within 15 days, go to the traffic management department of the public security authority at the place where the motor vehicle driver's license was issued or where the violation occurred to participate in a seven-day study of road traffic safety laws, regulations, and related knowledge. After the motor vehicle driver completes the study, the vehicle management office shall conduct an exam on road traffic safety laws, regulations, and related knowledge within 20 days.

What Are the Symptoms of Insufficient Differential Oil?

When a car's differential lacks oil, a humming abnormal noise will occur in the rear axle. Below are some related introductions about the differential: 1. When the differential is low on oil, it is essential to promptly visit an auto repair shop or a 4S store to add oil to prevent affecting the normal use of the car; 2. Depending on the principle and type, differentials can be categorized into gear-type differentials, central differentials, anti-slip differentials, LSD differentials, Torsen differentials, etc. When the differential malfunctions, abnormal noises will occur in the rear axle, thereby affecting the normal use of the car; 3. There are many reasons for differential failure, including not only insufficient differential oil but also differential gear wear and improper gear adjustment. If the gears are worn, they cannot match other components during operation, and the friction between parts will cause abnormal noises in the differential. In such cases, the differential gears must be replaced. If the spacing between gears is not properly adjusted, it can also lead to abnormal noises, requiring readjustment.

How to Determine If the Car Paint Has Exposed the Primer?

Methods to determine if the car paint has exposed the primer are as follows: 1. Use your fingernail to scratch the mark and feel the indentation. If the scratched area can catch the sliding of your nail, it indicates the scratch is relatively deep, and there is a high possibility that the primer has been damaged. 2. If you only feel a slightly rough indentation, it generally means only the surface paint has been scratched, and the primer remains intact. In this case, polishing and waxing will suffice. Precautions for car paint repair: 1. Do not use water other than soft water for cleaning, including hot water, alkaline water, and water with high hardness. 2. Avoid washing the car under the scorching sun, and never wash the car immediately after the engine has cooled down, as this can lead to premature aging of the engine. 3. Do not use high-pressure water streams to wash the car body. 4. Avoid using random stain removers.
