What to Do When the Engine Fault Light Comes On in a New Car?

If the engine fault light comes on, you can follow these steps to address the issue: First, check whether the engine is running normally. Look for signs such as shaking, black smoke emission, or difficulty starting. If any of these issues are present, avoid restarting the engine. Note: If the light is red, do not restart the engine under any circumstances. If the engine is running normally and the car can be driven, proceed to a service station as soon as possible to diagnose the problem. The service station can easily read the fault code using a portable diagnostic tool, allowing for targeted repairs based on the fault information. If the engine is running normally, the owner can also try gently reconnecting all wiring harness connectors, as a loose connection might be the cause. Alternatively, repeatedly turning the key to the ON position might reset the light. Generally, the engine fault light may come on due to the following seven reasons: Sensor malfunction: This includes sensors such as the coolant temperature sensor, crankshaft position sensor, air flow sensor, intake air temperature sensor, and oxygen sensor. If these sensors are damaged, poorly connected, or their signals are interrupted, the car's ECU cannot accurately obtain engine data, triggering the fault light. Fuel or oil quality issues: If the recommended fuel or engine oil is not used, it may cause engine wear, leading to the fault light illuminating. Poor combustion of the air-fuel mixture: This can result in engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the fault light will turn on as a warning. Issues such as faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can cause poor combustion. Turbocharger problems: Issues with the intake boost pipes or turbocharger can also trigger the engine fault 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, which can, in severe cases, trigger the fault light. A dirty or uncleaned air filter can cause intake issues. Exhaust problems: Exhaust system faults can also cause the engine fault light to come on. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings. The catalytic converter is the most frequent culprit. Using leaded gasoline, lead- or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system issues can all 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 may prevent the engine from operating normally, triggering the fault light.

What to Do If You Run a Red Light?

You can check and handle the violation through methods such as checking the vehicle violation website, phone inquiry, mobile SMS inquiry, mobile app inquiry, and offline terminal inquiry. Running a red light refers to the act of a motor vehicle violating the prohibition of passage during the red light phase at a signal-controlled intersection or road section, crossing the stop line and continuing to drive. According to Article 2, Paragraph 1, Item 2 of the "Scoring Standards for Road Traffic Safety Violations," driving a motor vehicle in violation of traffic signal lights will result in a deduction of 6 points. According to Article 26 of the "Road Traffic Safety Law": Traffic signal lights consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light indicates permission to pass, and a yellow light serves as a warning. Article 44: Motor vehicles passing through intersections shall proceed according to traffic signal lights, traffic signs, traffic markings, or the direction of traffic police. Methods for Traffic Violation Inquiry: Traffic violation inquiry refers to checking the violations of motor vehicles against traffic management regulations through online or terminal inquiries. Website Inquiry: You can search for vehicle violation inquiries and enter vehicle information to check. Phone Inquiry: To inquire about violations, you can call the local 114 (area code + 114) or 12580 for traffic violation confirmation. Violations can only be handled at the traffic police station in the location where the violation occurred or where the vehicle license was issued. For on-the-spot violations, such as those directly caught by traffic police, they must be handled at the location of the violation. Mobile SMS Inquiry: Open the SMS interface on your phone; enter WZ followed by the license plate number and color in the message content; enter 1062650001 as the recipient and click send. Mobile App Inquiry: Open the Traffic Management 12123 app, click "More," select "Violation Inquiry" to find any unprocessed violations, and clear them. Offline Terminal Inquiry: You can visit the local traffic management hall and use the self-service inquiry machine to enter the license plate number and check recent violation records. Here are some tips to avoid running a red light: First, look at the arrow light, then the circular light: Currently, there are two types of indicator lights: arrow traffic lights and circular indicator traffic lights. When arrow lights are present, first check the arrow light and then the circular light to avoid running a red light. Note: When encountering a circular red light, you can turn right; when encountering an arrow signal light, if the right-turn arrow is red, you cannot turn right, otherwise, it will be penalized as running a red light. Brake in time: When the red light turns on, do not let the front of the vehicle cross the stop line. If the front wheels accidentally cross, and the rear wheels follow, the electronic camera will capture it, and it will be penalized as running a red light. If the front wheels have just crossed the stop line when the signal turns red, do not proceed through the intersection; wait for the green light before moving. Check the green light countdown before proceeding: When the green light flashes, if there is a countdown, you can judge based on the remaining time; if there is no countdown, and the vehicle is close to the intersection with high speed, you may proceed to avoid running a red light due to untimely braking. If the speed is slow and the vehicle is far from the intersection, brake immediately to stop and avoid running a red light.

Is the Suspension the Same as the Shock Absorber?

Suspension is not the same as a shock absorber. Below are detailed introductions to both: 1. Suspension: The suspension system refers to all the force-transmitting connecting devices between the car's frame and the axle or wheels. Its function is to transmit forces and torques between the wheels and the frame, buffer the impact from uneven road surfaces to the frame or body, and dampen the resulting vibrations to ensure smooth driving. 2. Shock Absorber: The shock absorber is used to suppress the oscillations from the spring rebounding after absorbing shocks and impacts from the road surface. It is widely used in cars to accelerate the attenuation of frame and body vibrations, thereby improving the vehicle's ride comfort.

Can the Three-Way Catalytic Converter Still Be Used After Water Ingress?

The three-way catalytic converter can still be used after water ingress. Below is an introduction to related content about water-damaged vehicles: 1. Specific definition of water-damaged vehicles: The vehicle starts to accumulate water, and internal components suffer damage due to the water. Water-damaged vehicles also have corresponding flood levels. 2. Classification of flood levels for water-damaged vehicles: Flood level one is when water just reaches the vehicle's chassis, flood level two is when water reaches half of the wheels, flood level three is when water almost completely submerges the tires, flood level four is when water reaches the engine hood, flood level five is when water completely submerges the engine hood, and flood level six is when water submerges the roof.

Can the front and rear tires of a rear-wheel-drive car have different widths?

Rear-wheel-drive cars can have different widths for the front and rear tires. Tires on the same axle must be the same width: The two front tires must be the same width, and the two rear tires must also be the same width. This means that tires on the same axle must have consistent specifications, including diameter, tire width, and wear level. However, if the front and rear tires have different widths, it is important to pay attention to driving safety, especially in extreme road conditions, and monitor tire usage. Tire diameter must be consistent: While the front and rear tires can have different widths, their diameters must still be the same. Otherwise, the car body may tilt, which is not conducive to safe driving.
