There are five possible scenarios when an exclamation mark appears on the car dashboard: general fault, automatic transmission fault, brake system fault, abnormal tire pressure, and lighting fault. The following is a detailed analysis of these five situations: General fault: A triangle with an exclamation mark inside indicates that the car's general performance, components, or functions have malfunctioned. Possible causes include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to go to a 4S shop for inspection to identify the source of the fault. Automatic transmission fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating that the transmission has a fault or the transmission lubricant is below the normal range. The transmission oil should be replaced promptly. Brake system fault: An exclamation mark inside a circle with parentheses represents a brake system warning, mainly indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Abnormal tire pressure: An exclamation mark below a horizontal line with parentheses represents the tire pressure monitoring warning light. This light will illuminate when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting fault: A yellow bulb with an exclamation mark is the lighting fault indicator, indicating that a car light has malfunctioned. Solution: Go to a 4S shop for inspection as soon as possible, or you can check it yourself. Focus on commonly used bulbs such as turn signals, fog lights, and interior lights to see where the problem lies.

How often should the urea filter be replaced?

The urea filter generally needs to be replaced every 50,000 to 60,000 kilometers. All vehicles with diesel engines require urea. Diesel engine vehicles have a urea nozzle in the exhaust pipe, which sprays a urea aqueous solution to purify the exhaust gas. Methods for cleaning the urea nozzle: 1. A small ultrasonic cleaner can be used for cleaning, with each cleaning session lasting no less than 15 minutes. During cleaning, functional tests can be performed to drive the nozzle, which improves the cleaning effect. 2. It can also be cleaned by soaking in warm water, with each session lasting no less than 15 minutes. Be careful not to immerse the plug in water.

What are the types of throttle position sensor failures?

Common failures of the throttle position sensor include: 1. Short circuit or open circuit of the idle switch. 2. Poor contact of the sliding contact of the linear variable resistor. 3. Improper installation or adjustment of the throttle position sensor, causing the idle switch not to close when the throttle is fully closed. Below is relevant information about the throttle position sensor: The throttle position sensor is also known as the throttle opening sensor or throttle switch. Its main function is to detect whether the engine is in idle condition or under load, whether it is accelerating or decelerating. Essentially, it is a variable resistor and several switches, installed on the throttle body.

What are the symptoms of a faulty valve?

Engine valve damage manifests with the following symptoms: 1. Reduced engine efficiency leading to decreased vehicle power. 2. Unstable idle or poor acceleration during engine operation. 3. Unstable cylinder operation causing black smoke emission from the engine. The causes of valve damage include: 1. Carbon buildup: Incomplete combustion and low-quality fuel lead to carbon deposits. 2. Damaged valve seals: These components prevent oil from entering the exhaust system and avoid abnormal oil consumption. 3. Valve burning: Reduced valve clearance prevents complete closure, trapping heat which leads to valve erosion by the combustion chamber's high-temperature flames.

How to Adjust Valves on a 4-Cylinder Car

Methods for adjusting valves on a 4-cylinder car: 1. Use standard shims during assembly to compensate for the valve clearance by measuring the gap and placing shims on the valve tappets. However, new shims will be needed once wear occurs. 2. Utilize hydraulic lifters, which automatically adjust the clearance. These do not require adjustment unless they fail. 3. For older gasoline engines, adjust the screw on the rocker arm to compensate for the clearance when the valve is fully closed. Function of valves: They are responsible for introducing air into the engine and expelling exhaust gases after combustion. The intake valve draws air into the engine to mix with fuel for combustion, while the exhaust valve expels the burned gases and dissipates heat.
