P0321 Trouble Code Solution

P0321 trouble code solution is as follows: 1. The P0321 trouble code refers to the ignition, distributor engine speed input circuit range and performance. 2. Possible causes of the fault include engine speed sensor failure, sensor damage, circuit connection failure or mismatch, connector failure, crankshaft position sensor signal disc abnormality, etc. 3. The engine speed sensor is the most basic output signal for engine operation. Its working principle is to calculate the engine speed and ignition advance angle, and cooperate with the camshaft position sensor signal to identify the first cylinder ignition top dead center. If the engine speed sensor fails, it will cause the engine to incorrectly calculate the ignition advance angle, resulting in delayed or deviated ignition. 4. The trouble code can be cleared if the sensor is broken, but the trouble code will appear after the car is started several times. After the trouble code appears, ignition difficulty will occur. If no iron filings are found after replacing the sensor, it is necessary to check the circuit, battery failure, or whether the engine has a cylinder misfire. 5. Failure to clear the car trouble code in time will cause the control center computer to lose normal records or the car's normal functions to be unavailable.

What maintenance items are required for a sedan at 50,000 kilometers?

Automotive maintenance at 50,000 kilometers should be divided into the following two scenarios: 1. If the vehicle has been properly maintained and underwent major maintenance at 30,000 kilometers, then at 50,000 kilometers, only an oil and oil filter change, four-wheel maintenance, brake inspection, chassis component check, and full vehicle fluid and lighting inspection are needed. 2. If major maintenance hasn't been performed, additional tasks such as throttle body cleaning, fuel injector cleaning, and replacement of the air filter, fuel filter, and cabin air filter are required. More details on automotive maintenance items are as follows: 1. Oil and oil filter replacement are mandatory for every maintenance session. Under the harsh conditions of high temperature and pressure inside the engine, the shelf life of oil is significantly reduced, and its performance degrades, eventually failing to protect the engine. The oil filter prevents impurities from mixing with the oil, which can cause oxidation, leading to sludge and clogging the oil passages. Both oil and oil filter should be replaced simultaneously. The air filter should be replaced every 10,000 to 15,000 kilometers. 2. If the vehicle's engine uses a timing belt, it should be inspected or replaced at 50,000 kilometers. However, if the engine uses a timing chain, replacement is not necessary. 3. Besides the items mentioned above, components like brake pads, tires, and the battery might also need replacement. If they haven't been replaced before, it's advisable to do so during the 50,000-kilometer maintenance. 4. Finally, maintenance also involves the inspection and servicing of dozens of items across multiple systems, including the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires.

What are the pros and cons of ECO mode?

The following are the advantages and disadvantages of ECO mode: 1. Advantages: The biggest benefit of activating ECO mode in a car is fuel savings, which reduces vehicle operating costs. 2. Disadvantages: The vehicle may experience slightly insufficient power during driving, and prolonged use of ECO mode can increase engine carbon buildup. Below are two operation methods for ECO mode: 1. Button-activated: Pressing the button activates the energy-saving mode. 2. Screen prompts: Informs the driver whether the operation is fuel-efficient. Daily usage primarily involves the button method. After enabling ECO mode, even excessive pressing of the accelerator pedal will be controlled by the system to restrain fuel consumption. Under ECO mode, throttle response may feel less sensitive as it controls the engine and transmission to operate strictly in the most fuel-efficient manner, featuring rapid gear shifts and smooth acceleration.

How long does it take for XPeng vehicles to be transported?

After new vehicles roll off the production line and are transported to various 4S stores and dealers, they can be picked up. The typical transportation time is around half a month. The following are the precautions for buying a car and the procedures required after purchase: Precautions for buying a car: When picking up the car, pay attention to the odometer reading, which is generally within 100 kilometers. Check for any debris in the radiator, whether the seat protective packaging and front plastic cover are intact, and if there are any stains on the interior seats and dashboard. Remember to request the production date and transportation date when picking up the car and compare them carefully with the vehicle you are picking up. Be sure to check the fuel level, as new cars usually have very little fuel, so remember to refuel after picking up the car. Procedures required after buying a car: The most important tasks after buying a car are obtaining the invoice and completing a series of procedures, such as purchasing car insurance, compulsory traffic insurance, and paying the purchase tax. Additionally, you need to apply for a temporary license plate for the new car so that it can legally drive on the road.

Should You Use External or Internal Air Circulation for Car Heating in Winter?

For short trips, you can use internal air circulation, while for long-distance driving, it is recommended to switch to external air circulation to replenish fresh air. Here is more information about car air circulation modes: 1. Car air conditioning systems have both internal and external circulation modes. Learning how to use them correctly ensures the health of passengers. 2. In winter, car air conditioning is used almost daily, as it provides both heating and cooling. 3. The heating principle of car air conditioning is much simpler than cooling. When heating, high-temperature coolant from the engine flows through the heater core, and the air blown by the fan passes over the heater core, allowing warm air to be emitted from the vents. 4. The cooling principle is slightly more complex. During cooling, the engine drives the compressor, which compresses refrigerant and delivers it to the evaporator. 5. The refrigerant expands and absorbs heat in the evaporator, cooling it. The cooled evaporator then cools the air from the fan, allowing cold air to be emitted from the vents. 6. Car air conditioning typically uses R134a refrigerant, which needs to be replaced periodically. It is advisable to replace the refrigerant on time; otherwise, the cooling speed may slow down, and the cooling effect may deteriorate.

Do car tires have a right and wrong side?

Tires have a right and wrong side. There is a numerical marking on the side of the tire that can determine the correct orientation of the tire. When installing the tire, simply place the side with the number facing the front of the hub. The following points should be noted when replacing tires: 1. For unidirectional tires, first consider the specific position where the tire and rim combination will be installed on the vehicle. Then, mount the tire onto the rim according to the rotation arrow indicated on the tire sidewall. After the tire and rim combination is installed on the vehicle, it is necessary to check and ensure that the rotation arrow on the tire sidewall is consistent with the forward direction of the vehicle. 2. For asymmetric tread tires, when mounting the tire onto the rim, it is important to ensure that the side of the tire marked with 'outside' in English is facing outward.
