What is the reason why the engine fault light on the BAIC prestige M20 dashboard keeps on?

Hello, it means that the engine electronic control system is faulty, you need to use the decoder to call up the fault code to know what the cause is, [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

This fault light will light up when there is any fault in the engine, it is recommended to go to the repair shop that has the decoder and ask them to check it to see what fault is causing the fault light to light up. Generally, there is no charge.

1. Identify the cause of the failure. For diagnostics of such faults in which the engine does not start, the battery should be tested first. It is necessary to find out if the engine does not start because the battery is insufficient.

2. Detect ignition timing. Timing belt slippage is the root cause of the failure that there is no electric spark and the engine cannot start.

3. Detect the starting system. In the case of faults such as engine failure to start, the first thing to do is to check the circuitry in the engine starting system. From the perspective of the most basic composition, the circuit of the starting system generally includes the following basic parts, that is, the battery, the starting motor and the cable connecting these parts.

Of course, in addition to this, ignition switches, starter relays or solenoid coils, as well as in-vehicle anti-theft systems, are also important components of the starting system.

4. Detect the quality of electric sparks. Once the circuitry of the starting system has been tested and proven to be fine-tuned, attention should be focused on why the engine is not working. Generally speaking, the ignition system of the engine is tested first, which is also the easiest inspection job.

In early ignition systems, you could easily remove the ignition coil and use a spark detector to detect if the spark was normal. When choosing a spark detector, an adjustable detector is preferable to a fixed design because it allows you to adjust the detector to a smaller gap so you can tell if there is no spark at all, or if there is an electric spark but it is weak.

5. Detect the fuel system. The diagnosis of the fuel system can be divided into two parts: the diagnosis of the fuel supply system and the diagnosis of the injector circuit system.

The fuel supply system can be detected by measuring the flow and pressure of the fuel. The best way to measure fuel flow is to inspect the line when there is a load in the fuel supply line.

Hello, this needs to be detected by the computer before the problem can be judged according to the computer prompts, so it is recommended to go to the repair shop to check it, I hope it can help you [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Summary. Hello friends, the reasons and solutions related to the engine fault indicator light of BAIC Weiwang M20 are as follows.

First, if the engine has obvious shaking, it is generally caused by the lack of cylinders in the engine, and this phenomenon needs to check the ignition coil and spark plug.

Second, if the engine does not have any jitter, the speed is normal, this is generally the fault of the emission system, it is recommended to clean up the carbon deposits, and the third is the problem of the vehicle's oxygen sensor caused by this phenomenon needs to be read by the computer**, according to the fault** to determine which sensor has a problem? Then replace it accordingly.

What are the problems with the BAIC Weiwang M20 engine fault indicator light on?

Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

Hello friends, the reasons and solutions related to the engine fault indicator light of BAIC Weiwang M20 are as follows.

Then replace it accordingly.

The sensor was replaced, and after a period of time, it was bright again, and it was cleaned again, and it was still bright after a period of time, and the computer troubleshooting or the oxygen sensor response was a little slow, resulting in the fault light being on, which was really impatient.

The engine fault light is not necessarily the engine failure, it may be the failure of the engine-related accessories, such as the oxygen sensor is faulty, and the engine fault light is also on. So you have to check it first, write down the fault**, and then ask him to help you eliminate the fault code, and then go for a while, if the fault light no longer appears, then there is no problem, if it appears again, then there must be a problem with this thing, and it needs to be dealt with. If I can help you, I hope to set it up, thank you.

The common reason for the engine failure light of this car is that the fuel injector is blocked, the gasoline pressure is insufficient, the gasoline pump is damaged and the oxygen sensor and the three-way catalytic poisoning are the faults. After that, clean it with clean water and then restart it to try, but it still doesn't work, considering that the valve seal and timing gear are caused by the failure, in this case, you need to disassemble the cylinder head and re-grind the valve. Usually be sure to use the national standard gasoline, which can effectively reduce the blockage of the fuel injector, the carbon deposit in the valve and cylinder, which is helpful for restoring the power of the engine and reducing noise.

Summary. The problem that the engine fault indicator light is on for BAIC Weiwang M20:

Damaged sensors, poor contact, or signal interruptions;

poor engine maintenance;

Poor fuel and oil quality;

Insufficient combustion of the mixture;

The problem that the engine fault indicator of BAIC Weiwang M20 is on: the sensor is damaged, the contact is poor or the signal is interrupted; poor engine maintenance; Poor fuel and oil quality; Insufficient combustion of the mixture;

Hello. The problem that the engine fault indicator light of BAIC Weiwang M20 is on: 1. The sensor is damaged, the contact is poor or the signal is interrupted; 2. Poor engine maintenance; 3. The quality of fuel and oil is not good; 4. The combustion of the mixture is insufficient; 5. Spark plug failure, ignition coil failure; 6. Fuel pump failure, oil circuit blockage, etc.

Hope it helps.

The failure light of the engine may be due to the internal carbon deposition of the original throttle valve or the internal carbon deposition of the engine, the dirty energy of the stable throttle, the dirty energy of the oxygen transmitter is out of balance, and the mixture ratio is out of balance, and this phenomenon is easy to occur when driving at low speed in urban areas, so it is necessary to pay attention to check whether the fuel injector is leaking.

Engine failure lights are usually lit for the following reasons:

1. Poor combustion state: Poor combustion state of the engine is the main reason why the engine failure light is on.

2. Engine knocking.

There are usually three scenarios:

The first case: the car is weak;

The second case: the car is weak and the engine noise is too loud;

The third case: there is an obvious knocking sound.

In the first case, some engine fault lights will turn on, some will not, and in the second and third cases, the engine fault lights will inevitably come on.

3. The internal reasons for the engine fault light to be on: the fuel quality is not good, the inside of the engine cylinder is not clean, and there is carbon deposit. (Photo by Zou Ting1) @2019
