Subject 4 500 questions are not useful. Here is the relevant introduction about Subject 4: Concept: Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driver's license assessment. Retake Instructions: If you fail Subject 4, you do not need to retake the previously passed tests (Subject 1, Subject 2, Subject 3). You can schedule a retake on your own, and no retake fee is required. There are no scheduling restrictions for the safe and civilized driving theory test, but the driving skill permit is valid for three years. If the applicant does not complete the test within the validity period, the passed subject scores will be invalidated.

How to Eliminate Severe Odors Inside the Car?

Methods to eliminate severe odors inside the car: 1. Minimize smoking and eating in the car, and frequently open windows for ventilation to maintain air circulation; 2. Cleaning the air conditioning filter is crucial. The air conditioning filter can filter out dust, bacteria, particulate matter, and other harmful substances from the external air entering the car. If not replaced regularly, it not only affects the air quality inside the car but also impacts the vehicle's cooling efficiency; 3. Using car perfume can uniquely capture odor molecules and purify the air through decomposition; 4. Bamboo charcoal bags can effectively absorb odor molecules with strong adsorption power. Placing several bamboo charcoal bags in the car is also a great option.

How to Deal with the Overflow Fault of B50 Secondary Air Pump?

Replace the secondary air valve. Here are the detailed related contents: Solution: Depending on the vehicle model, the secondary fuel supply operation varies. However, for European vehicles, the fuel pump typically operates once when the driver's door is opened and the ignition key is turned to the ON position, and then continues to work after ignition. Working Principle: The engine drives the air pump crankshaft via two V-belts, which in turn drives the piston to pump air. The compressed air is then directed into the air reservoir through a guide pipe. On the other hand, the air reservoir supplies gas to the pressure regulator fixed on the air pump through a pipe, thereby controlling the air pressure in the reservoir. When the air pressure in the reservoir drops below the set value due to leakage, the valve in the pressure regulator returns to its original position via the return spring, disconnecting the air pump's control circuit, and the air pump resumes pumping.
