How to Test the Crankshaft Position Sensor?

If the crankshaft position sensor is damaged, the rotation angle of the crankshaft cannot be determined. The engine control unit (ECU) will not receive signals from the crankshaft position sensor, and to protect the engine, it will not ignite or inject fuel. The symptoms exhibited by the car include no high-voltage spark, no fuel injection, and failure to start. The most obvious sign is the illumination of the engine warning light on the dashboard. The methods to test the crankshaft position sensor are as follows: 1. You can determine its condition by measuring the voltage. Turn on the ignition switch and measure the voltage between the two signal wires and ground; it should be 1.4V. This is the preset voltage on the signal wires by the engine control unit. 2. When cranking the starter, measure the signal voltage of the crankshaft position sensor; it should be close to 1.6V. 3. If there is an open or short circuit inside the sensor, in the signal wiring, or within the engine control unit, the ECU will be unable to receive the crankshaft position signal, and the engine will fail to start.

What is the normal range for ignition advance angle data?

Ignition advance angle refers to the crankshaft rotation angle from the ignition moment until the piston reaches the top dead center of compression. Different vehicle models have different ignition advance angles, typically ranging between 8°-15° during idle. Here is more information about ignition advance angle: 1. The ignition advance angle is controlled by the engine control unit (ECU), which receives signals including engine speed, air flow meter, throttle position, coolant temperature, intake air temperature, oxygen sensor, and knock sensor to determine the ignition advance angle. 2. Factors affecting the ignition advance angle are engine speed and the combustion speed of the air-fuel mixture. Higher engine speeds result in shorter time for the crankshaft to rotate through the same angle, requiring a larger advance angle to achieve the corresponding advance time. The combustion speed of the mixture is influenced by the mixture composition, engine design, and other factors such as combustion chamber shape and compression ratio.

When will the China VI emission regulations be implemented?

The implementation timeline for the China VI emission standards is divided into two phases: 1. Phase One: Starting from July 1, 2020, all vehicles sold and registered must comply with the China VI-A standard. 2. Phase Two: Starting from July 1, 2023, all vehicles sold and registered must comply with the China VI-B standard; some cities will implement the China VI light-duty vehicle emission standards ahead of schedule. Methods to distinguish whether a vehicle meets China VI-A or China VI-B standards are as follows: 1. Check the relevant content on the approval certificate. The vehicle certificate contains many key pieces of information, including the emission standard, which will clearly indicate the national emission standard the vehicle complies with. 2. Query through specialized websites. You can find specific vehicle identification numbers, such as the engine number and chassis number, then visit the Motor Vehicle Environmental Protection Network. By entering these two numbers, you can query the relevant vehicle environmental information, including the implemented emission standard.

How to Cancel the Tire Pressure Warning?

The method to eliminate the tire pressure warning on the Sagitar: First, turn on the ignition switch, then press and hold the tire pressure monitoring reset button. After hearing a "ding" sound, release the button. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, completing the tire pressure reset. Tire pressure monitoring automatically checks the tire pressure in real-time while driving and alerts the driver in case of tire leaks or low pressure to ensure driving safety. There are three commonly used types of tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. The system automatically alerts when the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect tire pressure warning systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of the two systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and an indirect system is used for all four wheels. Compared to using only a direct system, this hybrid system reduces costs and overcomes the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time pressure data for all four tires like a direct system.

What does 360-degree surround view mean?

360-degree surround view refers to a 360-degree panoramic reversing camera system. It is a parking assistance system that integrates real-time bird's-eye view images of the vehicle's surroundings with ultra-wide angles and seamless stitching through the car's display screen. This helps drivers understand blind spots around the vehicle and park more intuitively and safely. It is also called a panoramic parking camera system or surround-view monitoring system. The functions of 360-degree surround view include: 1. Providing more intuitive auxiliary driving image information. 2. Significantly reducing scraping accidents during parking. 3. Assisting with urban driving in crowded areas.

What is the China 6 standard?

China 6 standard refers to the vehicle emission standards. Compared with the 'China 5' standard, 'China 6' will strictly control the emission limits of pollutants. Under the exclusion of working conditions and test influences, the carbon monoxide emissions of gasoline vehicles will be reduced by 50%, the emission limits of total hydrocarbons and non-methane hydrocarbons will be reduced by 50%, and the nitrogen oxide emission limits will be tightened by 42%. The implementation time of the China 6 emission standard is divided into two phases: 1. The first phase: From July 1, 2020, all sold and registered vehicles must meet the China 6A standard. 2. The second phase: From July 1, 2023, all sold and registered vehicles must meet the China 6B standard; some cities will implement the China 6 light-duty vehicle emission standard in advance.
