Why don't the BMW headlights turn on when unlocking at night?

Testing Procedure for Throttle Position Sensor

Throttle position sensor is also known as throttle opening sensor or throttle switch. The testing procedure for throttle position sensor is as follows: 1. Read data stream. When reading the data stream of TPS, slowly press and release the accelerator pedal for observation to prevent floor mats from obstructing the opening or closing of the throttle, which may lead to inaccurate test data. 2. Measure the voltage of throttle position sensor. The signal voltage of throttle position sensor increases with the opening of throttle. When the throttle is fully opened, its signal voltage is close to 5V, and when the throttle is closed (idle), its signal voltage is about 0.5V. 3. Test by unplugging the sensor connector. For cars equipped with automatic transmission, if it is suspected that the abnormal throttle position sensor (TPS) causes the automatic transmission to shift impact, the TPS plug can be unplugged for test driving, and manual shifting can be used. If the upshift and downshift are smooth at this time, it means that the mechanical part of the automatic transmission is normal, the problem lies in the control part, and the TPS may be faulty.

Is the 10th-generation Accord compliant with China National V or VI emission standards?

The 10th-generation Accord complies with China National V, the fifth-stage national emission standard for motor vehicle pollutants. This standard, equivalent to Europe's Euro 5 emission standards currently in effect, imposes stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. Taking the 2021 10th-generation Accord as an example, it is a mid-size sedan with body dimensions of 4893mm in length, 1862mm in width, and 1449mm in height, featuring a wheelbase of 2830mm and a curb weight of 1495kg. This model is equipped with a 1.5T inline 4-cylinder turbocharged engine, delivering a maximum torque of 260Nm and a maximum power of 143kW, paired with a continuously variable transmission (CVT).

What to Do If the Car Door Seal is Poor?

If the car door seal is poor, you can adjust the latch striker inward. Use a ratchet wrench that matches the fixing screws of the door latch striker to loosen the striker, then move it slightly inward to make the door close tighter. After several adjustments, you can find the optimal position, which will enhance the door's sealing performance, make the closing sound more solid and pleasant, and reduce driving noise. Solutions for excessive car noise include: 1. Paste sound-absorbing foam material under the engine hood; 2. Install sound-absorbing cotton material at the bottom of the trunk and on the wheel arches on both sides of the trunk; 3. Install professional damping plates in areas prone to noise; 4. Install sealing strips inside the doors; 5. Replace the tires.

What is the tire specification for the Ford EcoSport?

Ford EcoSport comes with two types of tire specifications. One is the Maxxis tire with the model number 205/60R16, and the other is the Michelin tire with the model number 205/50R17. Here, 205 indicates the tire width of 205mm, 60 represents the aspect ratio of 60%, R stands for radial construction, and 16 denotes the wheel diameter of 16 inches. Taking the 2019 Ford EcoSport as an example, it belongs to the compact SUV category with body dimensions of 4345mm in length, 1785mm in width, and 1659mm in height, a wheelbase of 2530mm, a fuel tank capacity of 52 liters, and a trunk capacity of 384 liters. This model is equipped with a 1.5L naturally aspirated engine delivering a maximum horsepower of 120PS, a maximum power of 88kW, and a maximum torque of 150Nm, paired with a 6-speed automatic transmission.

What to Do If 92 Octane Gasoline Is Accidentally Filled with 98 Octane?

Filling a car that normally uses 92 octane gasoline with 98 octane is generally not a problem, but long-term mixing of different octane levels should be avoided. If a vehicle is designed for 95 or 98 octane gasoline and is filled with 92 octane, it may cause issues, especially if 92 octane is used continuously over time. This can lead to increased knocking frequency and accelerated engine wear. Different octane levels have varying utilization rates and combustion efficiencies in the engine. The octane rating represents the ratio of the actual gasoline's anti-knock properties to those of standard gasoline, with higher numbers indicating stronger anti-knock performance. Standard gasoline is composed of isooctane and n-heptane, and higher octane numbers are not necessarily better. It's important to choose the appropriate gasoline octane based on the engine's compression ratio.

How to judge the distance between front and rear through the rearview mirror?

Use the following methods to judge the distance of the vehicle behind in the left lane through the rearview mirror: 1. If the body of the rear vehicle has entered the danger zone to the left of the dotted line in the rearview mirror, it indicates that the distance from the rear vehicle is very close, and turning at this time is not allowed. 2. If the left side of the rear vehicle's body is close to the boundary between the safety zone and the danger zone, you should be vigilant, but it is still safe to signal and turn at this time. 3. If the rear vehicle is in the safety zone, located in the center of the rearview mirror, it indicates that the distance from the rear vehicle is 15-20 meters, and you can proceed with the turning operation normally. 4. If the rear vehicle is in the safety zone, located to the right of the center of the rearview mirror, it indicates that the distance from the rear vehicle is relatively large, and you can proceed with the turning operation normally. Here’s how to judge the distance with the right rearview mirror: 1. If the rear vehicle occupies half of the rearview mirror area, and only half of its body is visible, the distance from the rear vehicle is very close. Your vehicle should maintain the current lane and not turn. 2. If the rear vehicle occupies half of the outer rearview mirror area, and the entire vehicle is visible, the distance from the rear vehicle is about 10 meters. You can signal and turn when the speed is slow. 3. If the rear vehicle occupies 1/3 of the outer rearview mirror area, and the entire vehicle is visible, the distance from the rear vehicle is about 15 meters, and you can proceed with the turning operation. 4. If the rear vehicle occupies 1/4 of the outer rearview mirror area, and the entire vehicle is visible, the distance from the rear vehicle is about 24 meters, and you can proceed with the turning operation.
