What does the TC light with a slash mean in the Envision?

The TC light with a slash in the Envision is the Traction Control System indicator. Press the button below the gear shift mechanism, then turn off the ignition and restart to reset the system, and the TC light with a slash will turn off. If the warning light remains on or comes back on while driving, repairs are needed. Possible causes for the TC light to illuminate include: solenoid valve failure; dirty oil clogging the solenoid valve filter; wear on the actuator gear and impeller, causing oil pressure leakage and triggering the alarm; dirty throttle with an opening reaching 20%; or the engine computer misjudging a TC fault. The working principle of the Traction Control System is to replace the mechanical connection between the accelerator pedal and the throttle with an electronic throttle control device. Sensors transmit the accelerator pedal information to the ECU, which generates a control voltage signal based on this information. The motor then adjusts the throttle according to the signal, reducing throttle opening and controlling wheel slip. For drivers operating the vehicle in rainy or snowy conditions, this can help reduce occurrences of wheel slip or loss of control.

What Causes Compressor Failure?

Compressor failure may be caused by liquid refrigerant entering the compressor, resulting in liquid compression, or poor oil return to the compressor. Below are detailed explanations of compressor failure: Liquid compression inside the compressor: When liquid refrigerant enters the compressor, it causes liquid compression, leading to the breakage of the scroll. As the liquid refrigerant enters the compressor chamber and undergoes compression, the incompressibility of the liquid exerts extreme lateral shear forces on the scroll, causing the fixed and orbiting scrolls to break and the compressor to seize. The solution is to immediately close the compressor's suction shut-off valve and stop the liquid supply by closing the expansion valve. Poor oil return to the compressor: Poor oil return (oil shortage) in the system prevents the compressor from delivering sufficient oil to all lubrication points. This causes friction at each lubrication point to intensify progressively from bottom to top. The friction leads to overheating of the orbiting scroll bushing, eventually causing it to burn out or even seize. In severe cases, the bushing may experience significant wear and breakage. It is essential to promptly check and replenish the compressor oil.

What Are the Hazards of Idling for 2 Hours to a Car?

Idling for 2 hours can cause several hazards to a car, including carbon buildup, excessive fuel consumption, and damage to the catalytic converter. The specific hazards are as follows: Carbon Buildup: If the engine runs at idle for a long time, the throttle opening will be very small, and the fuel injector will spray highly concentrated fuel to keep the engine running. Therefore, idling itself is more likely to cause carbon buildup compared to driving or highway speeds. Prolonged idling will inevitably lead to more severe carbon buildup in the engine, directly affecting the car's power and comfort. Excessive Fuel Consumption: According to tests, idling for three minutes consumes fuel equivalent to driving one kilometer. This means that idling for 2 hours can consume almost 2–3 liters of fuel. Catalytic Converter Damage: Prolonged idling results in an overly rich air-fuel mixture in the engine, leading to low oxygen content in the exhaust gases. The unburned mixture may combust at the catalytic converter, which can easily damage it.

What Causes the Vehicle to Shake When Shifting from D to R Gear?

The shaking may be caused by the following three reasons: 1. The engine or transmission mount rubber is broken or damaged, causing the engine or transmission to not be properly connected and cushioned, resulting in vibration when shifting gears. 2. The engine ignition system or intake system is not functioning properly, causing unstable engine speed and leading to vehicle vibration. However, after reading the data stream of the faulty vehicle's engine, all data indicators show normal, the engine speed is very stable, and the speed needle does not swing back and forth with the vibration. Therefore, this possibility can basically be ruled out. 3. The transmission's lock-up clutch is not working properly, causing a rigid connection of the torque converter, thus leading to vibration. But after reading the data stream of the faulty vehicle's transmission, all data indicators are normal, and the torque converter slip value of the transmission is within the normal range. Additionally, if the lock-up clutch is abnormally engaged, the engine speed needle would also swing back and forth when the vehicle shakes. Therefore, it can be preliminarily judged that the fault of this vehicle should not be caused by damage to internal components of the transmission.

What is the difference between D and S gears in an automatic transmission?

The following are the differences between D gear and S gear: 1. D gear stands for Drive gear. The advantage of D gear is that it is more fuel-efficient compared to S gear, but the disadvantage is that it provides less power. 2. S gear is the Sport mode, where the engine runs at higher RPMs, and the transmission shifts up later and down earlier. The advantage of S gear is better vehicle performance, while the disadvantage is poorer fuel economy. It is suitable for overtaking or climbing hills. Below are the methods for switching between different gears in an automatic transmission: 1. Shifting from P to R or R to P requires pressing the shift lock and applying the brake. 2. Shifting from R to N does not require pressing the shift lock or applying the brake. 3. Shifting from N to R requires pressing the shift lock and applying the brake. 4. Shifting from N to D requires pressing the shift lock and applying the brake. 5. Shifting from D to S requires pressing the shift lock, but neither releasing the throttle nor applying the brake is needed. 6. Shifting from S to D can be done by directly pushing the lever, without releasing the throttle or applying the brake.

What Causes the Engine Light to Come On in a Car?

Engine light illumination can be caused by sensor issues, turbocharging problems, or exhaust system malfunctions. Below are the specific reasons for the engine light coming on: Sensor Issues: Sensors include coolant temperature, crankshaft position, air flow, intake air temperature, and oxygen sensors. When these sensors are damaged, have poor connections, or experience signal interruptions, the vehicle's ECU cannot accurately obtain engine data, triggering the engine warning light. Turbocharging Problems: Intake boost piping and turbochargers can also cause the engine warning light to illuminate. The most common issue is turbocharger damage, often accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Exhaust System Issues: Components include rear oxygen sensors, catalytic converters, exhaust camshafts, and bearings. The most frequent cause is catalytic converter failure. Factors leading to catalytic converter malfunction include using leaded gasoline, lead/silicon-based lubricant additives, physical damage to the converter, or fuel system failures.

Does the size of a motorcycle sprocket affect speed?

Motorcycle sprocket size does affect speed, with specific details as follows: 1. If the front sprocket has 14 teeth and the rear sprocket has 38 teeth, the bike will have less power at low-speed starts but consume slightly more fuel. However, at high speeds, it can reach around 100 mph, is more fuel-efficient, and produces less vibration. 2. If the front sprocket has 15 teeth and the rear sprocket has 38 teeth, the bike will have better acceleration at low speeds compared to a 14-tooth front sprocket, be more fuel-efficient, and perform better on flat roads. However, it lacks power when climbing hills, and while it is faster at high speeds than the 14-tooth setup, it struggles on inclines, making it suitable only for flat terrain. 3. If the front sprocket has 15 teeth and the rear sprocket has 45 teeth, the bike will have strong starting power and perform well at low speeds when carrying loads or on mountainous roads. However, it vibrates more, consumes more fuel, and cannot match the high-speed performance of a 38-tooth rear sprocket. Most factory motorcycles come with a 15-tooth front and 45-tooth rear sprocket setup. Fuel consumption varies based on riding speed, and each rider's fuel usage may differ slightly.
