The oxygen sensor in the old Passat is located on the exhaust manifold, with one in front of the catalytic converter and another behind it. The front oxygen sensor detects the oxygen content in the exhaust, sending signals to the ECU, which then adjusts the air-fuel ratio. If the catalytic converter is damaged, a warning light will appear on the dashboard, indicating the need for replacement. The catalytic converter is a crucial component on the exhaust manifold, reducing pollutant levels in the exhaust, which benefits environmental protection. The old Passat is a mid-size car produced by SAIC Volkswagen, with body dimensions of 4870mm in length, 1834mm in width, 1472mm in height, and a wheelbase of 2803mm.

What is the replacement method for tires with tire pressure monitoring?

The replacement method for tires with tire pressure monitoring is: 1. With the car powered on but not started, simultaneously press the unlock and lock buttons on the car key for 3 to 5 seconds until the vehicle beeps twice; 2. Unscrew the valve cap of the left front wheel and continuously deflate the tire for about 15 seconds until a short beep is heard to confirm the setting; 3. Follow the above sequence to reset the car tires in the order of left front wheel, right front wheel, right rear wheel, and left rear wheel. The functions of tire pressure monitoring are: 1. It will promptly alert when there is rapid or slow air leakage due to a nail puncture; 2. It will alert when tire looseness causes unbalanced friction, leading to high tire temperatures reaching 70 degrees Celsius to prevent blowouts; 3. It will alert when the tire pressure is below the vehicle's set limit due to prolonged lack of inflation, preventing low pressure from causing tire temperature rise and blowouts.

How to Adjust Unequal Wheelbase on Both Sides of a Vehicle?

Vehicle with unequal wheelbase on both sides needs to be repaired at a professional 4S shop. Below are the specific impacts of unequal wheelbase: 1. Space: Since many vehicles position their front and rear seats between the front and rear axles, a longer wheelbase generally provides more space between the front and rear seats. Vehicles with shorter wheelbases won't have much interior space because the wheelbase length significantly affects cabin space. However, it's not accurate to simply say that a shorter wheelbase means less space; engine placement planning also plays a crucial role. 2. Turning Radius: A longer wheelbase results in a larger turning radius, requiring greater steering angles. Under the same conditions, vehicles need wider road space when making U-turns. This often leads to situations where vehicles may require secondary adjustments to complete turns on narrower roads.

Should Japanese cars use 0W20 or 5W30 engine oil?

Most Japanese cars use 0W20 engine oil. However, there is no single, standard, or consistent answer to this question. The type of engine oil to use is not inherently related to the country of origin of the vehicle but depends on factors such as the region, driving habits, and the specific model. To determine which grade of oil to use, it is recommended to refer to the vehicle's user manual and follow the instructions provided. Japanese cars generally refer to vehicles produced in Japan or Japanese-branded cars manufactured in other regions. Japanese cars have gained a significant market share globally due to their high cost-performance ratio, fuel efficiency, and excellent craftsmanship. The main brands of Japanese cars include: Toyota TOYOTA, Nissan NISSAN, Honda HONDA, Subaru SUBARU, Mazda MAZDA, Mitsubishi MITSUBISHI, Isuzu ISUZU, Suzuki SUZUKI, and Daihatsu DAIHATSU.

How Thick is the Front of a Tire?

Generally, the tread thickness of a car tire is about 13mm (7mm for tread pattern depth and 6mm for tread thickness), with the sidewall thickness being 5mm. Below is extended information about car tires: 1. Structure: Car tires can be divided into pneumatic tires and solid tires based on the carcass structure. The vast majority of modern cars use pneumatic tires. Depending on the internal air pressure, pneumatic tires can be categorized into high-pressure, low-pressure, and ultra-low-pressure tires. 2. Low-pressure tires: Low-pressure tires are widely used in various types of vehicles. Pneumatic tires can also be classified into tube tires and tubeless tires based on their structure. Passenger cars commonly use tubeless tires. 3. Inside the tire: Depending on the arrangement of the inner cord layers and cushion layers, tires can be further divided into radial tires and bias tires. Radial tires are predominantly used in vehicles. The sidewalls of tires are all marked accordingly.
