Roewe 350 engine fault light is on, what is the reason,

The spark plug has been changed, the air filter has been changed, the oil and filter element have been changed, the throttle valve has been cleaned and the light is still on. The cold car starts early, drives for a few minutes, and it will be fine after it is turned off. 2. Get up early and don't light up for a while. At present, the waste oil is more than 8.5-9, and it used to be 6.5-7.5. Sometimes it's boring to refuel, and the car is still shaking. Please. Get up early, wait a few minutes for the cold train to start, and then call after it is closed. 2. Start early, but don't open for a while. At present, the waste oil is more than 8.5-9, and it used to be 6.5-7.5. Sometimes it's boring to refuel, and it still shakes. Please tell me why the timing chain is long and needs to be replaced. I tried, but I couldn't. Roewe 350, 90% are timing chains. If I change gas stations, most of the chains will be dead. Buy an obd head and test it yourself. Dont Ask For Help is very fuel efficient. I, if it is a promotion, I will eliminate it and change it for a day or two. Before the change, another one was changed in 1992, and it was added in two days in 1995. Now, 95 chain tension is available. As long as the fault code is turned on, the fault light will not go out even if the function is restored. For example, if the intake pressure sensor is faulty, it must be read by the diagnostic equipment to eliminate the code. If yes, the fault light is on, for example, which cylinder is on fire, and the fault is detected, but it is not detected later, and the fault light goes out. Generally, the engine fault light is turned on, which can be divided into one type, and the exhaust emission is not up to standard. Engine system faults, such as accelerator pedal sensor, accelerator position sensor, air flow meter and crankshaft position sensor, or poor line contact, will cause the engine fault light to light up. Some vehicle gearbox system faults are also indicated by the engine fault light, such as internal faults, slippage and temperature of the gearbox. After the fault light is turned on, there are two situations: First, although the light is turned on, there is no abnormal feeling after it is turned on. Acceleration and braking are normal, so the car can run normally at present. It is possible that a sensor has a fault and it is fine now, or some external conditions and interference, or this fault does not affect the driving of the car at all, but it may have a certain impact on emissions. In this case, you can continue driving temporarily, and the fault light is on, but the car is not normal, such as severe jitter. In this case, it is best not to continue driving and ask for rescue of the trailer. If it is far away from the repair shop, you can force driving, because there is obvious fault phenomenon, which means that there is a serious fault. Continuing driving will aggravate the fault, or if this fault occurs, the damage will gradually accumulate and develop into another fault. It is not recommended to continue driving. Is it possible to reset the fault code all the time, or hello? There are many similar situations. The problem is to go to 4S to check your estimate. You can check and repair it, go to the repair shop or 4 S. Just try it. Could it be that there is something wrong with the oil, or would it be a problem to try another gas station? Check the nozzle, check the oil pump, find a professional point yourself, and the master will help you. There are still a lot of engineering problems, workmanship or key engine fault codes. There are many reasons, which are generally caused by poor oil products, and the problems of throttle, solenoid valve, sensor and carbon deposition are not excluded. It is suggested to go to the 4S shop as soon as possible to detect the cause of the fault and use the computer to eliminate the fault code. I hope the answer will help you. The engine trouble light is on. There are many reasons, such as oil and sensors. It is suggested to go to the repair shop and read the fault code with a computer to see what the specific problem is, and then deal with it, although the reason is bright. Because of the power age and high compression ratio of the press engine, the use of marked gasoline feels that the quality of gasoline is poor or the use exceeds the standard, which is a big reason. It is suggested that gas stations with large traffic flow should be filled with oil, and the speed should be restored within two days on the premise that the marked gasoline does not shake. If not, check other reasons. It's my pleasure to answer questions from riders. If you are satisfied, please adopt it. Generally, the engine fault light is on for the following reasons: 1, and the combustion state is not good. Due to poor combustion condition, the engine fault light is on. 2. Engine knocking generally occurs in one case: the first case: the car is weak, and the first case: the car is weak and the engine noise is too high. The first case: there is an obvious knocking sound. In the first case, there is. In the first case, the engine fault light is bound to light up. 3. The engine fault light is on, and the internal reason is (1) poor fuel quality. 2. The engine cylinder is not clean, and there are deposits and carbon deposits. @20 19.
