Engine immobilizer system locks due to low battery power, power interruption, or the use of illegal keys. Low battery power or power interruption: The anti-theft system will interpret this as a car theft attempt. Use of illegal keys: Opening the ignition switch with an illegal key will cause the immobilizer system to lock. Use an automotive diagnostic tool to clear the fault code. Definition of immobilizer system: Engine immobilizer is a locking system developed for vehicles. Since car door locks have a certain rate of mutual opening, which reduces the vehicle's anti-theft capability (English name: Immobilizer). For vehicles equipped with an engine immobilizer system, even if thieves can open the doors, they cannot drive the car away.

What is the cause of the P3073 fuel pump circuit electrical fault?

There is a short circuit in the wiring between the fuel pump and the fuel pump controller. The following is an introduction to electrical faults: Electrical faults include internal faults and external faults. 1. Internal faults: Some faults in electrical equipment are caused by internal factors, such as electromagnetic force, electric arc, heat generation, etc., which damage the structure of the electrical equipment or cause insulation breakdown of insulating materials. Such faults are called internal equipment faults. 2. External faults: Other faults in electrical equipment are caused by external factors, such as power supply voltage, frequency, three-phase imbalance, external force, and environmental conditions, leading to the formation of faults in the electrical equipment. Such faults are called external equipment faults.

Can You Still Drive with a Faulty ABS Sensor?

ABS sensor failure is not recommended for continued driving. When the ABS light is on, it indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, making it difficult for the driver to slow down or adjust the vehicle's trajectory, posing significant safety risks. Common causes for the ABS warning light staying on: Cause 1: The ABS speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting its ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle's speed or the wheel's slip rate, thereby failing to issue appropriate commands to adjust braking. How to handle: Clean the dirt off the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal function. Cause 2: Poor signal quality due to loose connections in the system wiring or poor contact in the ABS relay, leading to system failure. The most common issue is a loose connection in the speed sensor wiring, which will also show as a poor speed sensor signal in the ABS computer's fault memory. How to handle: Check all wiring connections and reconnect any loose ones.

Can Putting Soap in a Car Make It Smell Good?

Putting soap in a car can make it smell good and also prevent glass from fogging up. Soap placed in a car has many benefits. New cars often emit a pungent odor, and placing a bar of soap inside can help improve the unpleasant smell. When driving in rainy weather, fog or water droplets may form on the rearview mirrors and windows, which can obstruct the driver's view. Applying soap evenly to the rearview mirrors and windshield before driving creates a thin protective film on the glass. This film alters the surface tension of water molecules, causing fog droplets to coalesce into larger water droplets that cannot remain on the glass. However, it's important to purchase soap from reputable physical stores or well-reviewed online shops. Some stores, to cut costs, add industrial fragrances or use inferior ingredients in their soap, which can be harmful to human health. During summer, high temperatures can cause soap left in the car to melt, releasing toxic gases into the vehicle and posing safety risks. Therefore, caution is advised when purchasing.

What is the fuel consumption of the CS75?

The Ministry of Industry and Information Technology (MIIT) comprehensive fuel consumption for the 2018 Changan CS75 1.5T model is: 6.5 (L/100km), and for the 2018 Changan CS75 1.8T automatic four-wheel drive model, it is: 8.8 (L/100km). Fuel consumption measurement methods: Tests can be conducted on the road or on a chassis dynamometer, and then the fuel consumption per 100 kilometers is calculated using the "flow meter method" or the "carbon balance method." The fuel consumption test method for passenger cars uses speeds of 90km/h and 120km/h; for commercial vehicles, the test starts at 20km/h, with speeds selected in multiples of 10km/h up to 90% of the maximum speed, and at least 5 test speeds are measured. Methods to save fuel: Different driving habits can affect a car's fuel consumption. During driving, frequent rapid acceleration or deceleration can increase the car's fuel consumption by 5%-10% compared to normal conditions.

What is the fuel tank capacity of the Corolla 1.6 in liters?

The fuel tank capacity of the Corolla 1.6 varies between 43L and 50L depending on the configuration. The vehicle features a turbocharged intake system, a continuously variable transmission (CVT), a front McPherson independent suspension, and a rear E-type multi-link independent suspension. In the same vehicle class, the Volkswagen Bora has a fuel tank capacity of 50L, while the Honda Civic has a capacity of 47L. During the actual refueling process, the amount of fuel filled may exceed the calibrated capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe limit, and there is additional space from the safe limit to the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the instrument panel, which is marked with 'E' (Empty) and 'F' (Full). When the needle is close to 'E', it indicates low fuel, and when it is near 'F', it means the tank is full.
