According to the data, about 30%of the Chinese traffic accidents each year, about 30%of which is due to the overheating explosion due to the excessive tire pressure, or the explosion caused by the high tire pressure.%.It can be seen that installing a tire pressure monitoring device is very necessary.So, which kind of tire pressure gauge is better?Is the tire pressure monitoring well or external?What should I do if the car tire pressure monitoring light is on?
The tire pressure monitoring is well set or external or external
Accuracy: The pressure and temperature sampling of the built -in sensor are empty inside the tire, which is true and accurate.The external formula is pressed on the valve core, and it provides sealing itself. It is a bit worrying. It is much affected by the external environment and the temperature may be deviated.
Use environment: The sensor is located inside the tire, and the work is more stable.External sensors may be adversely affected by accidental impact and wading.
Anti -theft: Although the external type has anti -theft nuts, it is not difficult to remove as long as the tools are used.The built -in need to be pulled out. It is estimated that no thief is willing to do it.
Battery life: The built-in designed life is more than 5 years (2 hours per day), and the external life is generally only 1-2 years.The external sensor is limited by the volume weight and can only use smaller buttons.Built -in commonly used battery specifications CR2450 (550mAh), and external commonly used battery specifications CR1632 (120mAh).
Installation: The external type can be installed by itself (the merchant will provide a wrench), which is very simple. It is done for a few minutes, but you need to twist it when you inflatable;Unplug it, pick up the tire machine, pry open a certain gap in the gas mouth position, replace the original gas mouth, and then make the balance of the movement. The inflation has no effect.The weight of the built -in sensor (with gas mouth) is usually about 30g, and the motion balance must be made.The weight of the external sensor is usually within 10g, but it is not balanced.
Cost: The cost of built -in materials is higher than the external type, so the price is higher.In addition, if the cost of installing and adding a balance, the four wheels need tens of dollars to one or two hundred yuan.
How to install tire pressure sensor
1. Press the "MENU" key on the steering indicator, select the "tire pressure display" item in the "mileage fuel information menu", and then press the SET/CLR key;
2. The drivers information center will display "tire pressure re -learning". Select "Yes", press the SET/CLR key, the speaker will ring 2 sounds;
3. The drivers information center will display "tire pressure learning and enable";
4. At this time, the left forward steering indicator will be on long, and the left front tire pressure will be increased (or decreases) After 8.3kPa, the speaker can stop pressing (or decompression) after making a sound;
5. Then "the right forward steering indicator will be bright", the right back, the left rear indicator lights are lit in order, repeated pressure or decompression operation of the remaining three tires in order;
6. After the operation of the four tires is completed, the steering indicator will be bright for 3 seconds, and the speaker will sound 2 sounds, indicating that the tire pressure learning is completed;
7. Use the air pressure pump to adjust the tire pressure to the required values ??(generally the air pressure of the 18 -inch wheels with 18 -inch wheels with T and flagship models is 240, and other 17 -inch wheels 225 tire pressure is 220). At this timeFor actual tire pressure, if you dont worry, you can use the tire pressure gauge to measure it. If the error is not too large, it will be complained.
What should I do if the car tire pressure monitoring light is on
1. The tire pressure monitoring light caused by tires is on
This situation is usually very slow, and it is impossible to find that tire for a while. At this time, you can measure it with a tire pressure gauge.For a few days, it may be checked.The 4S shop, the usual treatment method of maintenance personnel is to adjust the pressure of the two front tires to 2.3, adjust the pressure of the rear tire to 2.4, and then cut off the tire pressure alarm, and let us run for another 3 or 4 days to see.There is no problem. The alarm may be tied to the police. You need to go to the 4S shop to let them help the inspection.
2. The tire pressure monitoring light is light and sometimes the tire pressure is too high
Usually the international GBT 2978-2008 standard stipulates that the inflatable pressure of car tires meets Table 1-Table 15 requirements:
Standard tires: 2.4-2.5bar; enhanced tires: 2.8-2.9Bar; Motivation: should not be greater than 3.5BAR.So when there is more than 3.0Bar with tires, it will also trigger tire pressure monitoring lights.
3. The tire pressure monitoring light caused by the long tire pressure driving time is on
This situation usually occurs: a tire tire pressure is too low, and the tire temperature is increased at high speed, and the tire pressure causes the tire pressure. At this time, it should be stopped to rest or replace the spare tires in time.
4. The tire pressure monitoring light caused by the low tire pressure of the tire pressure for a long time is on
When the air pressure is below 1.8, the tire pressure monitoring light is on, so it should usually be checked to see if the tire pressure detector is normal.When the car is in the event, if the tire pressure monitor does not report to the police in time, there is a problem with the tire pressure monitor; if it is the ignition switch on/start, the indicator light and the TPMS indicator light are turned off at the same time.In this case, the original receiver of the vehicle is not learned, or the receiver controller has been replaced, and the receiving controller has not been learned.You can go to the 4S shop and ask professionals to use handheld learning tools to re -obtain all tire sensor IDs to bind the receiving controller.
