Damage to the car sensor can directly affect driving safety to a certain extent. If the wheel speed sensor is damaged, it not only causes slight deviations in the speed display on the dashboard but also leads to unstable engine idling and reduced acceleration performance. The main sensors in a car are as follows: 1. Airflow sensor: The airflow sensor is usually installed between the air filter and the throttle body to measure the amount of air inhaled by the engine, converting it into an electrical signal provided to the ECU as a reference signal for fuel injection timing. If it malfunctions, the car may experience idling vibrations, weak acceleration, increased fuel consumption, and black smoke from the exhaust pipe, thereby affecting the engine's performance. 2. ABS sensor: The ABS sensor is typically located near the wheel bearing, outside the hub bearing and inside the brake disc, to monitor the vehicle's speed. During emergency braking, it feeds the wheel speed back to the braking system, which then controls the wheel's rotation to achieve optimal braking effect. If it fails, the ABS will not function, causing the wheels to lock up during emergency braking, leading to skidding and loss of control. 3. Throttle position sensor: The throttle position sensor is installed on the throttle body to detect the throttle opening. It works in conjunction with the throttle via a lever mechanism, measuring the throttle opening angle's voltage signal and transmitting it to the ECU as a reference signal for fuel injection volume and ignition timing correction. If it malfunctions, it can result in abnormal engine idling, engine vibrations, and delayed acceleration response.

A faulty sensor can indeed affect safety, and I've found the impact varies by location. If the ABS sensor fails, you'll feel the car locking up or skidding during braking, especially in rainy conditions, which can easily lead to loss of control and accidents. The anti-lock braking system won't function properly, increasing braking distance—just thinking about it is scary. Engine sensors like the oxygen sensor, while not directly threatening safety, may cause increased fuel consumption and trigger the engine warning light. Over time, this could damage the catalytic converter, leading to costly repairs. Then there's the airbag sensor—if it malfunctions, the airbags won't deploy during a collision, which is extremely dangerous. I once neglected to check my sensors, and a minor issue went unrepaired, nearly causing a rear-end collision. Since then, I always ask technicians to inspect all sensors during regular maintenance. My advice: at the first sign of abnormal symptoms, like dashboard warning lights or unusual vehicle behavior, get it checked at a professional shop immediately. Don't wait until an accident happens to regret it.

In my opinion, a faulty sensor definitely poses a safety hazard, with the key issue being which sensor is affected. ABS and TCS sensor failures are the most severe, directly impacting braking and traction control. On slippery roads during turns or emergency braking, the vehicle could lose control and roll over. If collision sensors malfunction and airbags fail to deploy, there's no protection in a crash. Additionally, engine sensors like wheel speed or temperature sensors, while seemingly minor, can accumulate issues leading to fires or tire blowouts. I once had a friend who ignored a minor sensor warning, resulting in sudden power loss and engine shutdown on the highway, nearly causing a rear-end collision. So in daily driving, if you notice steering wheel vibrations or abnormal engine sounds, get it checked immediately. From a safety perspective, spending money on sensor repairs is better than paying for accidents—car insurance doesn't cover all risks. Developing good observation habits ensures peace of mind while driving.

Sensor malfunctions can impact safety. If critical sensors like the ABS related to braking fail, the car may skid when braking, increasing the risk of accidents. Airbag sensor failures are even worse—if they don't deploy during a crash, the consequences can be severe. Other sensors, like those for the engine, may not be immediately life-threatening, but prolonged neglect could leave the car stranded on the road. I recommend checking the dashboard before driving and taking action if any warning lights appear. Simple fixes can be done yourself, but it's best to have a professional inspect them. In short, don't ignore small issues—they can escalate into major problems.

What Causes Engine Shaking and Stalling After Ignition?

Engine shaking can be attributed to the following reasons: Engine Misfire: An engine misfire primarily refers to one or more cylinders not functioning properly. This is typically manifested by noticeable intermittency in the exhaust gas flow, severe shaking of the exhaust pipe, and a distinct sensation of engine vibration, sometimes accompanied by a sputtering sound. This is often related to ignition coil failure. Worn or Loose Engine Mounts: Engine mounts are rubber blocks placed between the engine and the frame. Their purpose is to reduce vibration and provide cushioning during engine operation, as well as to secure the engine in place. Once these mounts become worn or loose, the engine's shaking will become significantly more pronounced. Replacing the engine mounts can greatly alleviate this issue. Carbon Buildup: Vehicles inevitably face carbon buildup issues, which include carbon deposits in the cylinders, throttle body, spark plugs, and intake system. When excessive carbon accumulates inside the engine, the vehicle's ignition energy, air intake efficiency, and air-fuel mixture ratio are affected, leading to unstable power output. Both idling and acceleration may exhibit shaking symptoms. It is recommended to visit a 4S dealership for an engine cleaning service to address this problem.

What does the appearance of ECO in an automatic transmission mean?

When ECO appears in an automatic transmission car, it means the economic driving mode is activated. ECO is an abbreviation derived from the words Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active Eco driving mode. When the ECO indicator light on the dashboard illuminates, it indicates that the vehicle's economic mode has been activated. Eco mode is categorized into active and non-active types. The difference lies in the fact that the active type has its own dedicated button, allowing the driver to choose whether to activate it. When the driver presses the Eco mode switch, the dashboard indicator light turns on, and the vehicle automatically adjusts settings such as throttle opening, transmission shift logic, and air conditioning output power. Non-active Eco mode does not have a dedicated button. When the ECO indicator light on the dashboard illuminates, it serves merely as a reminder function. The Eco system automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the ECO indicator light. Most cars utilize the active Eco driving mode, meaning they have their own switch button. Therefore, during daily driving, we can activate the Eco mode. However, it is unnecessary to activate Eco mode when the speed exceeds 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of Eco but also impact the vehicle's power performance. Additionally, the Eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed, causing the Eco mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, the Eco mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the Eco mode will not operate under these conditions.

How to Solve Fogging on Side Windows in Rainy Days?

In rainy days, fogging on side windows can be addressed using toothpaste, water repellent, or air conditioning defogging. Specific solutions for fogging are as follows: On rainy days, evenly apply toothpaste or soap on the car's side window glass and wait for a while until the applied soap hardens. Then, wipe it clean with a towel. A wax layer will form on the glass surface, which has excellent water-repellent properties, effectively preventing fogging or water droplets on the rearview mirror that may cause blurred vision. Purchase a specialized water repellent and evenly spray or apply it on the rearview mirror. A protective film will form on the rearview mirror surface, which also has excellent hydrophobic properties, effectively preventing fogging or water droplets on the rearview mirror, ensuring clear visibility. Turn on the car's air conditioning to cold air and adjust the air outlet to the front windshield to quickly clear fogging on the glass. If you want to completely eliminate fogging, you can turn on the air conditioning to hot air before starting the car and blow it directly on the front windshield for 3 minutes. This can fundamentally prevent glass fogging. Air conditioning cooling can also dehumidify and achieve the fastest defogging effect. The driver can turn on the air conditioning's cooling mode and adjust the blowing mode to the windshield position. In about ten seconds, the fog can disappear.
