What Causes the Engine Fault Light to Illuminate in a New Car While It Can Still Run Normally?

When the engine fault light comes on, it may serve as a warning indicating that certain system parameters in the vehicle might have exceeded the set range. In such cases, the vehicle can usually continue to operate, and the light is typically yellow. There is also a more severe situation where the light turns red, signaling a very serious fault. Although the vehicle might still be drivable, it is crucial to stop immediately, turn off the engine, and refrain from further driving for safety reasons, followed by a thorough inspection to identify the fault. The engine fault light may illuminate due to the following seven main reasons: Sensor Malfunction: Sensors such as those for coolant temperature, crankshaft position, air flow, intake air temperature, and oxygen sensors may become damaged, have poor connections, or experience signal interruptions. When the vehicle's ECU cannot accurately obtain engine data due to these issues, the engine fault light will illuminate. Fuel or Oil Quality Issues: Failure to use the fuel or oil as specified by the manufacturer may lead to engine wear, triggering the fault light. Poor Combustion of Air-Fuel Mixture: Incomplete combustion can cause engine carbon buildup or knocking. Once detected by the oxygen sensor and reported to the ECU, the fault light will illuminate as a warning. Issues such as faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can lead to poor combustion. Turbocharger Problems: Issues with the intake boost system or turbocharger can also cause the engine fault light to come on. The most common problem is a damaged turbocharger, often accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake Issues: Problems with the vehicle's air intake system may lead to clogged engine passages, and in severe cases, trigger the engine fault light. A dirty or uncleaned air filter can cause intake problems. Exhaust System Issues: Faults in the exhaust system, such as problems with the rear oxygen sensor, catalytic converter, exhaust camshaft, or bearings, can also cause the engine fault light to illuminate. The catalytic converter is the most common culprit, often affected by the use of leaded gasoline, lead- or silicon-based lubricant additives, physical damage, or fuel system malfunctions. Anti-Theft System Fault: If the vehicle's electronic anti-theft system malfunctions or if there is a mismatch between the anti-theft controller and the engine control unit, the engine may fail to operate correctly, and the fault light will illuminate. If the engine fault light comes on, follow these steps: First, check whether the engine is running normally and if there are any issues like shaking or smoke. If such problems exist, avoid restarting the engine. Notably, if the light is red, do not attempt to restart the engine under any circumstances. If the engine can be started, turn it off and wait for 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'ON' position (without depressing the clutch). The vehicle will perform a self-check upon powering up. Observe whether the fault light turns off after 5-10 seconds. If the light remains on, visit a service center as soon as possible. Technicians can use a portable diagnostic tool to read the fault codes, identify the issue, and perform targeted repairs.

Is 13 Volts Normal for Car Power Generation?

This is the battery voltage, not the generator's power output. 13V is still considered normal. The reason for high voltage in a car generator is usually a malfunctioning voltage regulator. It is necessary to inspect the generator's regulator and replace it according to the generator model. If the generator's voltage regulator fails, causing loss of control or abnormal voltage detection circuitry, the generator may produce excessively high voltage. Engine voltage malfunction: When the generator's voltage regulator fails, the generator produces excessively high voltage, which increases with higher RPM. If the voltage is not extremely high, it may cause the generator to overheat, battery overheating, bulb burnout, or charging circuit damage. In severe cases, it can lead to battery swelling, explosion, or complete failure, charging circuit fires, or even ECU damage.

What are the impacts of not scrapping a zombie car on the owner?

Not scrapping a zombie car can affect the renewal of the driver's license or the annual vehicle inspection. Below are detailed explanations regarding the driver's license: 1. Overview: The full name of the driver's license is the motor vehicle driver's license, also known as a "driving license," which is a certificate required by law for individuals who drive motor vehicles. Driving a motor vehicle requires certain driving skills, and those lacking such skills may cause traffic accidents if they drive recklessly. Driving without a license is prohibited. 2. Notes: The permission to drive a vehicle is granted through the issuance of a driver's license. This indicates that obtaining a driver's license is a formal process that must be conducted by a specialized authority.

What brand is koober shock absorber?

koober is the shock absorber of the Coolbo brand. The following are specific introductions to the symptoms of shock absorber failure: 1. Abnormal noise: If the shock absorber makes abnormal noise when the vehicle is driving on bumpy roads, it is very likely that the shock absorber is damaged. 2. Oil leakage: Check the shock absorber through the wheel arch with a flashlight. When oil leakage is found on the outside of the shock absorber, it indicates that the shock absorber is already damaged. 3. Loose chassis: When the vehicle is driving on bumpy roads, if the body posture is found to be excessively bumpy and unstable, it is generally a problem with the shock absorber.

What Causes the Constant Illumination of the Hyundai Verna's Brake Light?

Reasons for the constant illumination of the Hyundai Verna's brake light: 1. Lack of brake fluid; 2. Damaged brake switch; 3. Worn or aged brake pads. If there is a lack of brake fluid, when the driver presses the brake pedal, the force applied to the pedal is transmitted by the piston of the master cylinder through the brake fluid to the brake calipers located at each wheel, causing the brake pads to contact the wheels and thereby stopping the vehicle. The brake light is usually installed at the rear of the vehicle, with a red-colored main body to enhance the penetration of the light source, making it easier for following vehicles to notice the braking of the vehicle ahead even under low visibility conditions, thus helping to prevent rear-end collisions.
