What does it mean when the throttle position sensor 1-2 is unreasonable?

An unreasonable position between sensor 1 and 2 is generally caused by the throttle. If the throttle has been replaced with an original equipment manufacturer (OEM) part, it is recommended to check whether the wiring from the throttle connector to the engine control unit (ECU) connector is damaged. Use a diagnostic tool to check the signal voltage of the throttle position sensor. In such cases, cleaning the throttle and performing a reset can be attempted. If the issue persists, replacing the throttle may be necessary. The functions of the throttle position sensor are as follows: 1. Detecting operating conditions: The throttle position sensor, also known as the throttle opening sensor or throttle switch, primarily detects whether the engine is in idle, load, acceleration, or deceleration conditions. It essentially consists of a variable resistor and several switches, installed on the throttle body. 2. Two contacts: The resistor's rotating shaft is linked to the throttle and has two contacts: a full-open contact and an idle contact. When the throttle is in the idle position, the idle contact closes, sending an idle condition signal to the ECU. When the throttle is in other positions, the idle contact opens, outputting a voltage signal corresponding to the throttle's rotation angle. The ECU uses this signal voltage to determine the engine's load and identifies acceleration or deceleration based on the rate of change in the signal voltage over time. The ECU uses this information to adjust fuel injection or perform fuel cut-off control.

What is the weight of a sedan?

Generally, the load capacity of a family sedan ranges from 375 to 400KG. The actual load capacity should strictly adhere to the weight indicated on the nameplate attached by the manufacturer at the time of production. The national standard sets the limit at 375 kilograms, meaning the vehicle's load capacity must not exceed this figure. Calculating based on the minimum standard of 375 kilograms, the car can accommodate four individuals weighing 150 pounds each, with an additional capacity for nearly 100 pounds of cargo (including fuel tank, spare tire, onboard tools, and fire extinguisher). Below are the damages caused by overloading to the vehicle: 1. Reduced braking performance and increased non-safe distance: Numerous factors influence a vehicle's braking distance, with changes in vehicle load directly affecting its length. Overloaded vehicles, due to increased inertia, require longer braking distances. The extension of the non-safe zone distance significantly raises the risk of traffic accidents. 2. Shortened lifespan of leaf springs and reduced vehicle clearance: Overloading subjects the leaf springs to excessive stress, causing continuous rebound during driving, which shortens their lifespan. Additionally, excessive load causes the vehicle to lower overall, reducing ground clearance and diminishing the vehicle's ability to pass through certain areas. 3. Accelerated tire wear and deformation: Overloading increases the weight on tires, leading to deformation. The heightened friction also results in a shortened tire lifespan.

Sedan Length?

Sedans are categorized into the following lengths: 1. Mini cars: Typically referring to models with a wheelbase less than 2400 mm, known as small vans, such as: Chery QQ3, Chang'an Honda, Geely Panda, etc. These models have a wheelbase of approximately 2340 mm, with the SMART FORTWO being smaller, having a wheelbase of only 1867 mm. 2. Small cars: Usually referring to models with a wheelbase between 2400 to 2550 mm, known as small cars, such as: Honda Fit, Toyota Vios, Ford Fiesta, etc. 3. Compact cars: A car with a wheelbase between 2550-2700 mm is generally considered a compact car, which is the mainstream model for domestic cars like Volkswagen, Toyota Corolla, Ford Focus, Honda Civic, etc. 4. Mid-size cars: Typically referring to models with a wheelbase between 2700-2850 mm, known as mid-size cars. These models are usually used for domestic and economy cars, such as: Honda Accord, Toyota Camry, Volkswagen Magotan, Mazda 6 Atenza. A sedan is a car with a passenger capacity of fewer than 7 people. A small car with a fixed roof is a vague generalization. Small cars with roofs and convertibles can be referred to as small cars.

What is the purpose of an engine guard plate?

The purpose of an engine guard plate is: 1. To prevent mud from encasing the engine, which could lead to poor heat dissipation; 2. To protect the engine from impacts caused by uneven road surfaces during driving, thereby extending the engine's lifespan and avoiding car breakdowns due to external factors damaging the engine. Engine guard plates are made from various materials, including hard plastic resin, steel, aluminum alloy, and plastic-steel. The main chemical component of plastic-steel is modified high-molecular polymer alloy plastic-steel, which offers excellent performance, convenient processing, and wide applications. Its characteristics include high rigidity, strong elasticity, corrosion resistance, and outstanding anti-aging properties.

How to Use Audi's Cruise Control?

Audi's cruise control usage method: The cruise control lever is located below the steering wheel. Pull the lever inward to activate the cruise control system. Then press the SET button to store the current speed. Moving the lever upward increases the cruise control speed, while moving it downward decreases the speed. Audi is a German luxury car brand, symbolized by four interlocking rings. It is now a subsidiary of Volkswagen Group, headquartered in Ingolstadt, Germany, with branches in many countries including China. Audi's main models include A1, A3, A4, A5, A6, A7, A8, Q1, Q2, Q3, Q5, Q7, Q8, TT, R8, and the S and RS performance series.

Can a car be jump-started while charging?

Yes. If you are using a dedicated charger, it is not recommended to jump-start the car while charging. However, if the battery is dead and another vehicle is providing a jump-start, you can start the engine while charging. But avoid doing this frequently as it can reduce the battery's lifespan. The battery is a crucial component of a car and is also highly susceptible to wear and tear. When the engine is not running, the battery supplies power to all the electrical components in the vehicle. Once the engine is started, the alternator takes over the power supply for the electrical systems. During engine startup, the ignition system, starter motor, and fuel delivery system all rely on the battery for power. If the battery is low on charge, the engine may fail to start properly. If the car is not used for an extended period, you can disconnect the negative terminal of the battery. For owners with a garage, it's advisable to periodically charge the battery using a dedicated charger. The typical lifespan of a car battery is around 3-5 years, but many batteries fail before reaching this duration due to improper usage habits. Avoid using electrical components for prolonged periods when the engine is off, such as leaving the headlights on or running the air conditioning. If the battery needs replacement, consider upgrading to an AGM (Absorbent Glass Mat) battery, which offers a longer lifespan and better charge/discharge performance compared to conventional batteries.
