What Causes the Engine Warning Light to Illuminate After Refueling?

If fuel and engine oil are not added according to the manufacturer's requirements, it may cause engine wear, leading to the illumination of the warning light. In such cases, the fuel in the tank should be drained, and the tank thoroughly cleaned. After cleaning, add gasoline that meets the required standards. Apart from fuel quality issues, there are six common factors that can cause the engine warning light to illuminate: Sensor Malfunction: Sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors may become damaged, have poor connections, or experience signal interruptions. When the car's ECU cannot accurately obtain engine data, the engine warning light will illuminate. Poor Combustion of Air-Fuel Mixture: Poor combustion can lead to engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Issues such as faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can cause poor combustion of the air-fuel mixture. Turbocharger Issues: Problems with the intake boost pipes or turbocharger can also trigger the engine warning light. The most common issue is a damaged turbocharger, accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake Problems: If the car's intake system is compromised, it may lead to clogged engine pipes, and in severe cases, the engine warning light will illuminate. A dirty or uncleaned air filter can cause intake issues. Exhaust Problems: Exhaust system faults can also trigger the engine warning light. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings. The catalytic converter is the most frequently affected component. Using leaded gasoline, lead- or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can easily lead to catalytic converter failure. Anti-Theft System Malfunction: If the car's electronic anti-theft system fails or the anti-theft controller does not match the engine's electronic controller, the anti-theft system can prevent the engine from operating normally, causing the engine warning light to illuminate.

What is the appropriate RPM for an automatic transmission engine?

Automatic transmission engine RPM between 1800 and 2000 is normal. Below is an introduction to automatic transmission: 1. RPM refers to the number of revolutions per minute of the engine crankshaft. The engine RPM relates to the number of work cycles per unit time or the effective power output of the engine. An automatic transmission does not require the driver to manually shift gears; the vehicle will automatically select the appropriate gear based on driving speed and traffic conditions. 2. Method for starting an automatic transmission car: 1. After sitting in the driver's seat, press the start button to turn on the ACC light. 2. Press the start button again for the vehicle to perform a self-check. 3. Press the brake pedal and press the start button to ignite and start the engine. 4. Press the foot brake, shift to D gear, and release the handbrake.

Is a Steering Wheel Cover Necessary?

Steering wheel covers are necessary, and their functions are introduced as follows: 1. Protect the steering wheel from wear and reduce vibration. 2. Enhance grip and friction, preventing slippage due to sweaty hands. 3. Improve responsiveness and safety while driving. 4. Steering wheel covers are easy to remove and clean. 5. They help protect the original steering wheel. Additional Information: 1. Steering wheels are categorized into: single-spoke, dual-spoke, three-spoke, and four-spoke designs. 2. The method to adjust the height of the steering wheel is: locate the lever at the bottom of the steering wheel; press the lever to adjust. 3. The function of the steering wheel is: to convert the force applied by the driver on the edge of the wheel into torque, which is then transmitted to the steering shaft, thereby changing the direction of the vehicle.

Does Water on Floor Mats Count as a Flood-Damaged Vehicle?

It counts as a flood-damaged vehicle. During daily use, sometimes rainwater on shoes can wet the floor mats when entering the car, or spilled drinks inside the car may also cause the mats to get wet. If the floor mats get wet under these circumstances, it does not count as a flood-damaged vehicle. However, if the vehicle is stationary and water rises above the floor level, soaking the mats, then it is considered a flood-damaged vehicle. Below are some tips for identifying a flood-damaged vehicle: 1. If there is rust on the steering column, seat rails, or seat rail screws, it is likely a flood-damaged vehicle. 2. Under the floor mat on the left side of the driver's seat, there are many wiring harnesses. If there is sediment inside these harnesses, the vehicle has been submerged in water. 3. Open the trunk and lift the cover to check for watermarks in the corners and inspect the rust condition of the onboard tools. Additionally, if the spare tire is new but the steel wheel rim shows obvious rust, it indicates that the trunk has been flooded, strongly suggesting the vehicle is flood-damaged.

How to Adjust the Rearview Camera?

We only need to turn on the vehicle's ignition switch, shift into reverse gear, and then go to the location where the rearview camera is installed at the rear of the vehicle. Generally, it is installed at the position of the license plate light on the trunk lid, or sometimes under the rear bumper. You can see that the rearview camera is lit, indicating it is working properly. The rearview camera should be installed with the center of the vehicle's width as the reference point to ensure a more comprehensive rear view.

How to Deal with Scratches from Tree Branches on a Car

First, clean the scratched area of the car body with dish soap. It's fine to use dish soap for car washing—don't listen to claims that it damages the paint, as this is simply not true. Apply Turtle Wax Scratch & Swirl Remover lightly over the scratched area, covering it in a straight line. Use the included polishing sponge to apply the scratch wax to the scratched area in a 360-degree circular motion, ensuring even coverage. It's best to follow up with polishing wax, using a method similar to the third step of applying scratch wax. Find a soft, dry towel and polish the waxed area once more with the towel.
