What are the eight major sensors in a car?

The eight major sensors in a car are introduced as follows: Coolant Temperature Sensor: The most easily observable sensor, it directly detects the operating temperature of the coolant. The coolant temperature sensor senses through a temperature measurement node installed in the radiator, and this reading can be easily seen on the dashboard. Oxygen Sensor: This is another frequently heard sensor name, and its function, as the name suggests, is related to "oxygen content." There are generally two oxygen sensors, one located behind the exhaust manifold and the other behind the catalytic converter. The former is called the front oxygen sensor, and the latter is called the rear oxygen sensor. The oxygen sensor determines whether the fuel is burning normally by detecting the oxygen content in the exhaust, and its readings provide crucial data for the ECU to control the engine's air-fuel ratio. Knock Sensor: Engine vibration is a problem many people have encountered, and one of the causes of this phenomenon is knocking. The data read by the knock sensor provides the ECU with important information to identify whether the engine is experiencing knocking. When knocking is detected, the ECU adjusts its ignition timing to reduce or eliminate the occurrence of knocking. Intake Pressure Sensor: Next are some sensors that people rarely hear about or even think exist. The first is the intake pressure sensor. This sensor measures the absolute pressure in the intake manifold based on the engine's load condition and converts it into an electrical signal, which is sent to the computer along with the speed signal as the basis for determining the basic fuel injection amount of the injector. Air Flow Sensor: The air flow sensor converts the inhaled air into an electrical signal and sends it to the ECU, serving as the basic signal for determining fuel injection. Throttle Position Sensor: This is the key sensor that controls the fuel injection amount when accelerating by pressing the accelerator. In fact, pressing the accelerator controls the throttle, not the fuel injector. Crankshaft Position Sensor: The crankshaft is located at the bottom of the engine in the oil pan, and its rotation is key to driving the pistons' up-and-down strokes. Its rotational speed directly reflects the engine's speed. The crankshaft position sensor is one of the important sensors in the ECU's ignition control system. It detects top dead center signals, crankshaft angle signals, and speed signals, allowing the ECU to issue correct ignition commands according to the cylinder's firing order. Oil Pressure Sensor: The purpose of this sensor is to detect the amount of engine oil inside the engine and then alert the driver via a warning light on the dashboard to replenish the oil in a timely manner.

Is It Normal for the Front of a Car to Get Very Hot?

It is normal for the front of a car to get very hot. The specific reasons are as follows: Reasons: When the engine is running, the external temperature can reach above 90°C, and the exhaust pipe temperature can exceed 500°C. Additionally, the heat insulation layer and underbody panels on the hood will block the dissipation of heat. Self-cooling mechanism of the car: If the engine temperature becomes too high, the fan will automatically turn on to continuously cool the engine. Once the engine temperature decreases, the fan will stop automatically. Additional information: Car bumper: The car bumper consists of three parts: the outer panel, buffer material, and crossbeam. It not only enhances the vehicle's appearance but also absorbs and reduces external impact forces, protecting the front and rear of the car body. Car engine hood: While ensuring engine heat dissipation, it provides excellent sound insulation, ensuring a comfortable ride even when the engine is running at high speeds. Moreover, the engine hood also offers dustproof and waterproof protection for the motor, battery, and various wiring inside the engine compartment.

How many meters can be captured for crossing a solid line?

There are two situations for crossing a solid line: Within 100 meters: Many beginners realize they are on the wrong path only when they reach the solid line area. For example, if you need to turn right at an intersection but are in the middle lane, you might only realize this upon reaching the intersection and attempt to change lanes at the solid line. In such cases, within 100 meters of the intersection, it's easy to be caught by traffic violation cameras. When many vehicles are queuing in the current lane: Some drivers choose to cross the line and change to a lane with fewer vehicles when facing long queues. This not only affects traffic conditions but also makes it easy to be captured by traffic violation cameras.

Is it a big deal if only 1 point is left on the driver's license?

It is not a big deal if only 1 point is left on the driver's license, as long as there are no further traffic violations resulting in point deductions within the current scoring cycle. If a motor vehicle driver's accumulated points do not reach 12 within a scoring cycle and all fines have been paid, the points will be cleared. If the points do not reach 12 but there are unpaid fines, the points will carry over to the next scoring cycle. Below is relevant information: Road traffic safety violations: The scoring cycle is 12 months, with a full score of 12 points. The cycle starts from the date the license was initially issued and continues in a loop, with points being cleared on the issuance anniversary date, which marks the beginning of the new scoring cycle. For example, if the initial issuance date of the driver's license is May 1, 2020, the scoring cycle runs from that date to the same date the following year. Point values for violations: If the accumulated points do not reach 12, the scoring system will automatically reset at the start of the next cycle. If the points reach 12, the traffic management department of the public security authority will confiscate the driver's license. The driver must then report to the traffic management department of the public security authority at the place where the license was issued or where the violation occurred within 15 days to attend a seven-day study session on road traffic safety laws, regulations, and related knowledge.

Can Traffic Management 12123 Pay Retake Fees?

Traffic Management 12123 may not necessarily allow payment of retake fees. Not all regions have activated the online payment function on the Traffic Management 12123 app. Here is additional information: The fees are collected by the vehicle management office: Retake fees are actually collected by the vehicle management office, and all retake fees for different subjects are clearly stipulated by the vehicle management office. Driving schools may also assist in paying or make unified payments, but some driving schools act as intermediaries, and the fees they charge may differ from the prices published by the vehicle management office. There are limits to retaking the driving test: The number of retake opportunities varies for different test subjects. Simply put, more expensive tests have restrictions, while cheaper ones do not. The retake limit for Subject 2 and Subject 3 is 5 times each. If all retake opportunities are used up, previously passed subject scores will be invalidated, and you will have to re-register for the test.

What is the proper distance for oncoming traffic in Subject 3 driving test?

When encountering oncoming traffic, it's best to maintain a 30 cm distance between the right side of your vehicle and the solid line on the right lane. Here are the relevant details: Oncoming traffic: This refers to two moving vehicles passing each other at a certain point, as you'll inevitably encounter narrow roads during actual driving. Subject 3 oncoming traffic scoring rules: 1) Failing to slow down and keep right when meeting oncoming traffic on roads without central separation facilities or centerlines, or failing to maintain safe distance from other vehicles, pedestrians, or non-motorized vehicles - 100-point deduction; 2) Not yielding when passing is difficult - 100-point deduction; 3) Poor judgment of lateral safety distance resulting in emergency steering to avoid oncoming vehicles - 100-point deduction.
