Why does the Ruifeng car trouble light turn on?

Causes, for reference only: 1. Damaged sensor, poor contact or signal interruption; 2. Poor engine maintenance 3. Poor fuel and oil quality 4. Insufficient combustion of the mixture; breakdown ; 6. Fuel pump failure, oil circuit is clogged; 7. The air conditioning filter element is clogged.

The specific situation is analyzed as follows: 1. Sensor problems; The sensors mentioned here include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc. When these sensors are damaged, have them repaired. Bad contact or signal interruption At this time, the car ECU cannot accurately obtain the engine data, which will cause the engine trouble light to illuminate. 2. Maintenance Problems: Poor engine maintenance is the most common cause of engine failure. We know that vehicles have a ccertain maintenance cycle. If the owner does not maintain it on time and has poor driving habits, it will increase the load on the engine operation. Ultimately, the trouble light can only be used to remind you. you need to take care of your vehicle.Love your car 3. Oil quality problem; The oil grade mentioned here includes fuel and engine oil. We know that fuel filled in cars is usually labeled, and engine oil is also divided into semi-synthetic. and entirely synthetic. Manufacturers generally recommend car owners to use What brand of fuel and what type of engine oil if the car owner does not add it as required, it will lead to long-term engine wear, and this does not It's no one's fault though. the fault indicator light comes on. Poor combustion of the mixture; spark plug failureengine ignition, ignition coil failure, fuel pump failure, oil circuit blockage, etc. will all lead to poor combustion of the engine mixture. Poor combustion of the mixture will cause carbon deposits or knocking problems in the engine, which will eventually be detected by the engine's oxygen sensor, after reporting to the ECU the fault light will naturally illuminate to warn of problems admission; Combustion in the engine is necessary. In this process, the air filter element is very important. If the car's air filter element is not clean and is not cleaned regularly, it will affect the car's air intake. time, it is likely to become clogged. In severe cases, the engine trouble light will illuminate. Overeating problems; the intake boost pipeline and turbocharging are often caused by damageto the turbocharger. At the same time, the vehicle will also experience oil leaks, heavy oil consumption and reduced power. My personal summary is for your reference.
