How to Eliminate the Exhaust Controller Malfunction Light?

What Causes a Car Key to Be Unresponsive?

Car key unresponsiveness can be attributed to the following reasons and solutions: Presence of Interference Sources: Interference sources around the car can disrupt the signals emitted by the car key and received by the antenna. Solution: Remove all aftermarket devices installed inside the car and then test drive. Key Battery Depletion: A dead battery in the key can prevent it from emitting signals, leading to unresponsiveness. Solution: Replace the key battery and test drive to check for any malfunction. Control Module Malfunction: Faults in the vehicle antenna or body control module can prevent the antenna from receiving signals or the module from recognizing them, affecting the car key's lock/unlock functionality. Solution: Visit a professional repair facility for inspection and repair.

Is October Too Early to Change to Winter Engine Oil?

It is acceptable to change to winter engine oil in October, but it should not be later than November. Engine Oil Grade: Since winter temperatures are relatively low, the low-temperature fluidity requirements for engine oil are higher. It is recommended to use engine oil with a grade below 5W, as it can effectively prevent freezing. Generally, engine oil with a "W" designation is for winter use. The number before the "W" represents the oil's low-temperature fluidity—the smaller the number, the lower the freezing point, the better the cold resistance, and the better the low-temperature fluidity. Proper Warm-Up: When changing oil in winter, if the engine is cold, the oil's fluidity will decrease due to low temperatures, making it difficult to drain the old oil completely. In this case, the engine should be warmed up appropriately. When the oil reaches a certain temperature, its viscosity decreases, fluidity improves, and it softens the sludge inside the engine, allowing it to be discharged along with the old oil.

How Far Can You Drive with a Tire Pressure of 196?

Tire pressure of 196 should not be driven on. A tire with excessively low pressure increases its contact area with the ground, leading to abnormal temperature rises inside the tire during driving, which can affect vehicle handling. Tire Pressure Check Cycle: Generally, a car's tire pressure should be checked at least once a month. It's important to adjust the tire pressure with each season change, with the ideal adjustment times being November and May. In November, as winter approaches, tire pressure usually decreases and should be slightly adjusted. In May, as the weather starts to get hotter, it's advisable to check if the pressure is normal. Precautions for Checking Tire Pressure: Particular attention should be paid during May. As long as the tire pressure is not significantly higher than the standard range, there's no need to deliberately lower it. If the tires are not under-inflated, there's no need to adjust them every month.

What are the reasons for a car not supplying fuel and failing to start?

Reasons for a car not supplying fuel and failing to start are as follows: Incorrect gear position: For automatic transmission models, if the gear is not in the P position when starting, the vehicle will not start. Therefore, it is necessary to enter the cabin and check whether the gear is in the P position. Battery depletion: Battery depletion is a significant reason for failure to start. Normally, the battery voltage must be above 12.4V to start the engine smoothly. If the battery is severely depleted, it must be replaced or jump-started. Starter motor damage: The starter motor is used to rotate the engine flywheel to start the engine. If it malfunctions, the engine will show no response when starting.

How Long Does a Car Last?

A car typically lasts for 15 years or 600,000 kilometers. The actual lifespan depends on usage and maintenance. Below are the factors affecting a car's lifespan and methods to extend it: Factors affecting a car's lifespan: Wear and corrosion, accumulation of dirt and deterioration, aging of non-metallic components such as rubber and plastic, material fatigue, deformation of parts or poor manufacturing quality, improper operation or misuse, incorrect repairs, and traffic accidents. Methods to extend a car's lifespan: Keep vehicle components clean, follow scheduled maintenance to inspect the engine and the entire vehicle, maintain good driving habits, and avoid traffic accidents.

Can I turn right from the side when there is a car in front?

When there is a car in front, you cannot turn right from the side. You should wait patiently for the car in front to leave before making a right turn. In the following special circumstances, you may use an adjacent lane to turn right: Road construction: While driving on the road, some sections may have construction occupying the driving lane. In such cases, vehicles can temporarily use the left or right lane to turn, and return to the original lane immediately after passing the obstacle. All left or right turns caused by construction will not be considered a violation and can be appealed even if recorded. Vehicle breakdown: If a vehicle in front has broken down or is involved in a traffic accident that occupies the right-turn lane, to avoid traffic congestion, you may use an adjacent lane to turn right and leave. When using an adjacent lane, pay attention to the distance between vehicles in front and behind to ensure safety. Illegal parking: If a driver has illegally parked on the side of the road, especially near an intersection, you may slowly use another lane to bypass and then turn right. If there is a traffic light ahead and you cross a solid line while bypassing, a special explanation can be provided.
