What Causes the Engine Speed Sensor to Malfunction?

Engine speed sensor malfunction may be caused by issues with the sensor's wiring leading to the engine control unit. If the wiring is intact, inspect other components. Below is additional information: Engine Speed Sensor: The engine speed sensor is an inductive sensor that captures engine speed and the precise angular position of the crankshaft (input system). A dedicated signal wheel for the engine speed sensor is installed on the flywheel. Design Principle: The signal wheel is designed as a toothed wheel divided into 60 segments. As the signal wheel passes the sensor, it generates an alternating voltage whose frequency varies with speed. The frequency indicates the engine's rotational speed. Sensor Function: To identify the crankshaft position, the signal wheel has a gap between two segments. The engine speed sensor detects engine speed. Together with the Hall sensor, it identifies the top dead center for cylinder 1 ignition, thereby determining fuel injection timing and ignition timing.

How to License a Newly Purchased Car?

The process of licensing a new car at the Vehicle Management Office is as follows: 1. Inspection: Take the car to the inspection site for a new vehicle check; receive the inspection process form, then proceed with tests for the vehicle's exhaust emissions, side slip, speedometer, etc. 2. Submit documents and receive license plates: Perform rubbing and photography of the vehicle; bring all required materials to the Vehicle Management Office window for submission, obtain a queue number, and wait for the next step to select a new license plate number, then receive the plates on the spot. Below are the documents needed for licensing: vehicle certificate of conformity, car purchase invoice, and compulsory insurance policy (commercial insurance can be purchased after licensing). In Beijing, Shanghai, and Guangzhou, proof of car purchase quota is also required. Before going to the Vehicle Management Office for licensing procedures, make three copies each of your ID card, temporary residence permit, vehicle certificate of conformity, car purchase invoice, and compulsory insurance policy for backup.

What does tire pressure monitoring alarm indicate?

Tire pressure alarm indicates that there is excessive deviation in pressure among the four tires or insufficient inflation, suggesting an issue with the vehicle's tire pressure that requires immediate inspection. Possible causes include: 1. Air leakage: The tire pressure monitoring light may illuminate due to a puncture causing slow air leakage. In such cases, it might be difficult to immediately identify which tire is affected. Use a tire pressure gauge to measure the pressure (recommended: front tires 2.3, rear tires 2.5). If pressure is low, inflate accordingly and then monitor the warning light. If it illuminates again after a few days, remove the tire for thorough inspection. 2. High temperature: The tire pressure monitoring light may also indicate overinflation. Prolonged driving with low tire pressure can trigger the warning light, typically occurring when a tire's pressure is too low, causing increased temperature during high-speed operation which subsequently raises the pressure. In such situations, promptly pull over to rest or replace with the spare tire.

How Many Times Can a Temporary License Plate for a New Car Be Applied For?

A temporary license plate for a new car can be applied for up to 3 times. Below are the application conditions for temporary license plates: 1. When driving the vehicle from the place of purchase to the place of use, a temporary license plate must be applied for at the vehicle management office in the place of purchase. 2. When transferring the vehicle registration and the official license plate has been surrendered, a temporary license plate must be applied for at the local vehicle management office to drive back to the original location. 3. For a new car that has not obtained an official license plate in the local area and needs to be driven to another location for modifications, a temporary license plate must be applied for locally. After modifications are completed, a temporary license plate must be applied for at the modification location to drive back to the original area. 4. When purchasing a car locally and needing to drive it to another location, a temporary license plate must be applied for locally to drive to the other location, and vice versa. 5. When the vehicle registration has not been finalized and temporary use is required.

Can You Still Drive with Engine Shaking, Lack of Power, and Jerking Sensation?

Engine shaking and lack of power during acceleration are caused by certain component failures, but whether you can continue driving depends on the actual reason behind the shaking. However, it is not recommended to continue driving. Below is additional information: Ignition System Failure: This situation may be caused by a misfiring cylinder, which is highly likely due to an ignition system failure. A misfiring cylinder means one of the engine's cylinders is no longer working, leading to reduced engine smoothness and insufficient power. Reduced Vehicle Power: You can still drive with reduced engine power, but several factors should be considered: engine carbon buildup, aging spark plugs, fuel grade, and engine system failures. Excessive Carbon Buildup in the Engine: Reduced vehicle power may be due to excessive carbon buildup inside the engine, which obstructs the intake system and prevents the engine from functioning properly. In such cases, timely engine cleaning is necessary.
