(1) The yellow symbol light indicates that there is a malfunction in the engine, but the malfunction does not affect the normal operation of the engine, but it must be detected and repaired;

（2）紅色符號燈，說明發(fā)動機(jī)有嚴(yán)重故障，正常情況下需要馬上報(bào)修的，如果在特殊路況下，可以應(yīng)急行駛，但需要時刻留意發(fā)動機(jī)的工作狀態(tài)。

(2) The red symbol light indicates a serious engine malfunction that requires immediate repair under normal circumstances. In special road conditions, emergency driving is possible, but the engine's working status needs to be constantly monitored.

儀表盤上的警示燈，有綠色、黃色和紅色，分別代表了緊急程度。亮紅燈基本上是要趕緊靠邊停車，以免造成安全事故或是嚴(yán)重?fù)p傷車輛部件；

The warning lights on the dashboard are green, yellow, and red, respectively representing the level of urgency. Turning on a red light is basically to quickly pull over and stop to avoid causing safety accidents or serious damage to vehicle components;

黃色燈亮，表示車輛存在異常或故障隱患，但還不足以對我們的行車安全造成直接影響；

The yellow light is on, indicating that the vehicle has abnormalities or potential faults, but it is not enough to directly affect our driving safety;

而綠燈，只是指示駕駛員需要相應(yīng)的操作（如倒車?yán)走_(dá)、巡航系統(tǒng)、動力模式開關(guān)、換擋提示燈等）。

The green light only indicates that the driver needs corresponding operations (such as reverse radar, cruise control system, power mode switch, gear shift indicator light, etc.).

發(fā)動機(jī)故障燈亮黃燈的5個原因：

Five reasons why the engine malfunction light turns yellow:

氧傳感器故障

Oxygen sensor malfunction

根本不是發(fā)動機(jī)及其相關(guān)部件出問題，而是傳感器寶寶生病了而亂報(bào)錯，發(fā)出不正確指示。

It's not that there's a problem with the engine and its related components at all, but rather that the sensor baby is sick and reports errors randomly, giving incorrect instructions.

這個情況下，車輛是能繼續(xù)開的，只是會導(dǎo)致發(fā)動機(jī)空燃比的控制有所偏差，比之前更費(fèi)油。處理方法也簡單，到華勝來把壞掉的傳感器換上新的傳感器就可以了，花費(fèi)不大。

In this situation, the vehicle can continue to drive, but it will cause a deviation in the control of the engine's air-fuel ratio, which is more fuel-efficient than before. The handling method is also simple, just come to Huasheng and replace the damaged sensor with a new one, which is not expensive.

冬季寒冷天

Cold winter days

在溫度較低的冬天，由于發(fā)動機(jī)的內(nèi)部溫度比較低，而汽車起步的時候，發(fā)動機(jī)需要達(dá)到一定的溫度才可以完成基本的監(jiān)測，這個故障就會被監(jiān)測出來，發(fā)動機(jī)故障燈就會亮起來，而當(dāng)發(fā)動機(jī)的溫度達(dá)到標(biāo)準(zhǔn)后，故障燈自燃消失。車子能繼續(xù)開。

In the colder winter, due to the lower internal temperature of the engine, when the car starts, the engine needs to reach a certain temperature to complete basic monitoring. This fault will be detected, and the engine fault light will light up. When the engine temperature reaches the standard, the fault light will self ignite and disappear. The car can continue to drive.

燃油品質(zhì)不好

Poor fuel quality

發(fā)動機(jī)故障燈又叫【發(fā)動機(jī)尾氣排放檢查燈】

Engine malfunction light, also known as engine exhaust emission inspection light

所以，當(dāng)此燈亮，也有可能是尾氣排放超標(biāo)了。如果你加的油，品質(zhì)沒保證，發(fā)動機(jī)尾氣排放容易超標(biāo)，發(fā)動機(jī)尾氣排放檢查燈就會亮起，甚至EPC燈、電子節(jié)氣門燈的黃燈都一并跳起來，生怕你不知道似的，就像唐僧在你眼前念叨念叨：“該換好點(diǎn)的油品，該換好的油品了”。

So, when this light is on, it is also possible that the exhaust emissions have exceeded the standard. If the quality of the oil you add is not guaranteed, the engine exhaust emissions are prone to exceeding the standard. The engine exhaust emission inspection light will light up, and even the yellow lights of the EPC light and electronic throttle light will jump up together, fearing that you may not know. It's like Tang Seng muttering in front of you, "It's time to change to a better oil, it's time to change to a better oil.".

解決方法

Solution

解鈴還須系鈴“油”，為了你愛車的“健康”當(dāng)然是更換好品質(zhì)的汽油，不要隨便到小加油站加油。另外，長期使用品質(zhì)差油，會損害三元催化器，換一個新的，可是要好幾千甚至上萬塊才能搞掂。

To solve the problem, you still need to tie the bell and use oil. For the sake of your car's health, of course, it is important to replace it with high-quality gasoline and avoid refueling at small gas stations. In addition, long-term use of poor quality oil can damage the three-way catalytic converter. Replacing it with a new one can cost thousands or even tens of thousands of yuan to fix.

解決方法

Solution

及時清除積碳,除此以外，還有進(jìn)氣管、排氣管泄漏、ECU發(fā)出警告也會導(dǎo)致出現(xiàn)發(fā)動機(jī)亮黃燈。發(fā)動機(jī)警示燈亮起并伴隨發(fā)動機(jī)抖動現(xiàn)象

Timely removal of carbon deposits, in addition to air intake and exhaust pipe leaks, and ECU warnings can also cause the engine to turn yellow. Engine warning light comes on and accompanied by engine shaking phenomenon

這種現(xiàn)象，90%是因?yàn)樨?fù)責(zé)點(diǎn)火部件出問題了，例如負(fù)責(zé)點(diǎn)火的火花塞、點(diǎn)火線圈或噴油嘴等其中一個壞掉了。

90% of this phenomenon is due to a problem with the ignition component, such as a broken spark plug, ignition coil, or fuel injector that is responsible for ignition.

解決方法

Solution

如果是火花塞壞了，更換新的火花塞，建議更換4個，相應(yīng)地，如果發(fā)現(xiàn)噴油嘴或點(diǎn)火線圈壞了，相應(yīng)更換新的就可以了。到華勝門店后，師傅也會進(jìn)行故障碼排查，更準(zhǔn)確地診斷出車輛的問題。

If the spark plug is damaged, replace it with a new one. It is recommended to replace 4 spark plugs. Correspondingly, if the fuel injector or ignition coil is found to be damaged, replace it with a new one. After arriving at the Huasheng store, the technician will also conduct fault code troubleshooting to more accurately diagnose the problem with the vehicle.
