What does the AFL light maintenance on the LaCrosse mean?

What are the reasons for the engine warning light to come on?

There are mainly 7 reasons for the engine warning light to come on: Sensor malfunction: The sensors mentioned here include coolant temperature, crankshaft position, air flow, intake air temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or signal interruption occurs, the car's ECU cannot accurately obtain engine data, which will cause the engine warning light to come on. Fuel quality issues: If fuel and engine oil are not added according to the manufacturer's requirements, it may cause engine wear and trigger the warning light. Poor combustion of air-fuel mixture: Poor combustion can lead to engine carbon deposits or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Spark plug failure, ignition coil failure, fuel pump failure, and fuel line blockage can all cause poor combustion of the air-fuel mixture. Turbocharging issues: The intake boost pipe or turbocharger can also cause the engine warning light to come on. The most common issue is turbocharger damage, accompanied by symptoms such as oil leakage, high oil consumption, reduced power, metal noise, and blue or black smoke from the exhaust pipe. Intake issues: If there is a problem with the car's intake system, it may cause engine pipe blockage, and in severe cases, trigger the engine warning light. A dirty air filter that is not cleaned regularly can lead to intake problems. Exhaust issues: Exhaust system faults can also cause the engine warning light to come on. The rear oxygen sensor, catalytic converter, exhaust camshaft, and bearing failure are all causes of exhaust problems, with the catalytic converter being the most common. Using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system faults can easily cause catalytic converter failure. Anti-theft system malfunction: If the car's electronic anti-theft system malfunctions or the anti-theft controller does not match the engine electronic controller, the anti-theft system can prevent the engine from operating normally, and the engine warning light will come on. If the engine warning light comes on, you can follow these steps: First, check if the engine is running normally and whether there are issues like shaking or black smoke. If so, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can start, turn it off for 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'ON' position without pressing the clutch. The car will enter self-check mode after powering on. Wait for 5-10 seconds and observe if the warning light on the dashboard turns off. If the warning light remains on, visit a service station as soon as possible. The service station can use a portable diagnostic tool to read the fault code, obtain fault information, and perform targeted repairs.

Why Aren't Motorcycles Automatic Transmission?

Because motorcycles have transmission methods that are more suitable for their own needs. Acceleration and Power: Continuously variable transmissions (CVT) provide smoother power output, but under the same displacement, their acceleration and power are inferior to models with gears, which is why most cross-type motorcycles are geared. Higher Fuel Consumption: Traditional transmissions rely on mechanical gear transfer, albeit with the addition of a clutch and several electromagnetic controllers, sensors, ECUs, etc. In contrast, automatic transmissions rely on hydraulic torque converter transmission, which has lower transmission efficiency, higher fuel consumption, and greater weight. Characteristics: Scooters primarily emphasize practicality and comfort, whereas cross-type motorcycles often highlight a sense of control.

What is the difference between turning on AC and not turning on AC in summer?

In summer, the differences between turning on AC and not turning on AC are as follows: 1. Increased fuel consumption: The A/C button controls the car's air conditioning. When the button's light is on, it means the compressor is working, which increases fuel consumption, primarily for cooling and blowing cold air. 2. Reduced engine load: The engine bears a relatively smaller load when AC is off compared to when it is on. 3. Acceleration: The car's acceleration is relatively faster when AC is off. 4. Comfort level differs: When AC is on, the car interior is cooler and more comfortable, while when AC is off, it mainly blows natural air.

What causes the noise when stepping on the brake of the 10th-generation Accord?

The reasons for abnormal noise when stepping on the brake of the 10th-generation Accord are as follows: 1. The braking speed is too slow: This abnormal noise is mainly caused by the braking speed being too slow when starting, which is a common issue for many automatic transmission car owners. 2. Corrosion of the brake disc and brake pads: This usually occurs after driving in the rain and then leaving the car unused for several days. The brake disc and brake pads rust and stick together, causing noise when starting to drive again. This can be resolved by applying butter or special lubricating oil to the connection between the brake pads and the brake calipers at a repair shop. 3. Material issues: Many brake pads nowadays are made of semi-metallic materials, containing a large number of metal fibers. Sometimes metal particles form, producing a harsh sound when stepping on or releasing the brake.
