Methods to determine if a camshaft position sensor is faulty: Use a multimeter to check the resistance between the sensor's terminal 1 and the ECU's terminal 62, the sensor's terminal 2 and the ECU's terminal 76, and the sensor's terminal 3 and the ECU's terminal 67. Under normal conditions, the resistance should not exceed 1.5 ohms. If the resistance is too high or infinite, the sensor is faulty and needs repair or replacement. Here are the symptoms of a faulty camshaft position sensor: 1. Difficulty starting the car, delayed ignition, or failure to start, with sudden stalling when the engine is hot. 2. Unstable idling and engine shaking. 3. Poor acceleration with noticeable jerking. 4. Increased fuel consumption and black smoke from the exhaust pipe. 5. Persistent illumination of the dashboard warning light.

What Are the Basic Knowledge Points for Car Maintenance?

Cars are prone to issues such as failure to start, steering wheel vibration at high speeds, and heavy steering. Below is relevant maintenance knowledge: 1. Failure to start: (1) First, check if components like the high-voltage wires have gotten wet due to rain. If so, dry the wet parts before attempting to start. (2) Next, inspect the spark plugs for damage. If damaged, simply replace them with new ones. (3) Check if the battery voltage is sufficient. Sometimes, leaving the lights on after parking can drain the battery. In such cases, put the car in second gear, press the clutch, and use another vehicle to tow (not recommended; it's better to have someone push). Once reaching a certain speed, release the clutch and turn the ignition switch (not recommended; the ignition should be turned on before pushing). If the issue is with the alternator, this method won't work. 2. Steering wheel vibration at high speeds: If the car feels unstable or the steering wheel shakes at high speeds, first check the tire balance if alignment and other components are fine. 3. Heavy steering: Causes include low tire pressure (especially in front tires), insufficient power steering fluid, or incorrect front wheel alignment. 4. Pulling to one side: To check, drive straight and release the steering wheel. If the car doesn't go straight, it's pulling. This could be due to uneven tire pressure or incorrect front wheel alignment. 5. Poor headlight sealing: If headlights aren't sealed properly, they can let in water during washing or rain, causing fogging due to temperature differences. Avoid high-temperature drying, as it can soften plastic parts or melt adhesive, worsening the issue. Normally, sunlight can evaporate moisture inside headlights. Frequent water ingress may indicate damage from collisions, requiring a service check.

What is the curb weight of the Verna?

The curb weight of the Verna ranges between 1070-1120kg, which is the pure vehicle weight measured without any items loaded inside the car. Generally, the weight range of passenger cars varies from 800kg to 2000kg. Below are specific details about vehicle weight: Vehicle weight indicators: The weight of a car, also known as curb weight, refers to the weight of the vehicle when it is fully equipped according to the manufacturer's technical conditions, including all standard items like spare tires and tools, and with all fluids filled. The curb weight represents the vehicle's own weight, which is the weight of the car ready for normal driving conditions plus any attached accessories. Relationship between weight and fuel consumption: The curb weight of a car is also an important parameter affecting fuel consumption. This is because the vehicle's fuel consumption is directly proportional to its curb weight, meaning that heavier cars tend to consume more fuel.

Does the BMW 525 Need Matching After Battery Replacement?

BMW 525 does not need matching after battery replacement. The process of replacing the battery for BMW: Flip to the back of the car key, you will see a small button, press it; Grab the key handle above and pull it upwards to see the metal mechanical key; Use the pulled-out mechanical key to pry open the car key cover, after a gap appears, apply a little force to open it; Remove the old battery and replace it with a new one; Cover the car key lid back and insert the mechanical key. Precautions for BMW battery replacement: Whether the car engine is running or not, as long as the ignition switch is in the on position, the battery connection line (or fuse) must not be removed. Because sudden power failure will cause the coils in the circuit to generate a very high instantaneous voltage, sometimes as high as nearly 10,000 volts, which will seriously damage the computer ECU and related sensors and other microelectronic devices.
