My car is modified with gas, the engine dashboard, the engine fault light keeps on the yellow light

Hello, according to your description, this is a normal phenomenon, because the engine failure lights of the burning car have to be lit. Usually, there will be a failure of the oxygen sensor, which is normal, don't worry, just use it with confidence.

Hello, it is very normal for this situation, for the vehicle after the gas is changed, the engine fault light will always be on, because the engine is not supplied with oil, so the fault light will be lit.

Hello, the computer receives different signals from the combustion of natural gas and the combustion of gasoline engines, and some models will turn on the fault light. This is normal, and it is recommended to check the sensor for problems.

The car itself is oil-burning, and if you modify and install a gas system, there will definitely be an engine failure on the dashboard, and it is normal for the lights to be on.

After changing the natural gas, it has an impact on the engine exhaust system, so the oxygen sensor detects that the emission system is abnormal, and the fault light on the instrument will turn on, which is very normal!

Hello, if you change the gas, the bright yellow fault light of the engine is normal, and it is the fault code of the intake pressure of the package.

This is of course an abnormal phenomenon, as long as it is in the starting state, the engine fault light is on is problematic and must be repaired.

Hello, this question of changing the gas is like this. Only the computer can eliminate the fault code, and then it can be solved.

Hello! If you change it yourself, it must be a fault of the engine, and it is best to go to the 4S store to check it with a computer.

It should show that you have a problem with the oil circuit.

Hello, your situation should be caused by not being installed when modifying, it is recommended to use a computer to test it.

Hello, if the engine failure warning light appears on the car dashboard, it is definitely not normal, it is recommended to check it.

If this is the case for you, it is best to use the computer to read the fault code and check the specific fault information.

Hello, this should be the place where your car has not been dealt with in the process of transformation, you can go back and use the computer to diagnose it and solve it in a targeted manner.

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. The fuel pump is faulty and the oil circuit is blocked; 7. The air conditioner filter is blocked.

sensor issues; The sensors mentioned here include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car can not accurately obtain the engine data, at this time it will cause the engine fault light to turn on. 2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that the vehicle has a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light to care about your car 3, oil quality problems; The oil quality here includes fuel and engine oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, which type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame.

Poor combustion of the mixture; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture is caused by the problem of engine carbon deposition or knocking, and these will eventually be detected by the engine's oxygen sensor and reported to the ECU, which will naturally turn on the fault light to warn of the intake air intake problem; When the engine burns, it needs to take intake, the air filter element is very important in this process, if the air filter element of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly, and it will be blocked for a long time, and if it is serious, it will cause the engine failure light to turn on. pressurization issues; Intake booster lines and turbochargers can also cause engine failure lights to illuminate.

The most common of these is turbocharger damage, while the vehicle can also experience symptoms such as oil leakage, high oil consumption, loss of power, metal noise, and blue or black smoke from the exhaust pipe. 7. Exhaust problems; Rear oxygen sensor, three-way catalytic converter, exhaust camshaft and bearing. The most common of these is a failure of the three-way catalytic converter that causes the engine failure light to illuminate.

The use of leaded gasoline, the use of leaded or silicone lubricant additives, the bump of the three-way catalytic converter, and the failure of the engine oil supply system are some of the factors that can easily cause the failure of the three-way catalytic converter. anti-theft system; If the car's electronic immobilizer fails, or if the immobilizer does not match the engine electronic controller, the immobilizer system will also cause the engine to not work properly and the engine fault light will be lit at the same time.

There may be the following reasons.

After the oil is changed, the reason why the fault light is on is the failure of the oxygen sensor, or the oxygen content in the exhaust gas is too high beyond the adjustment range of the ECU, so the engine fault light will be on, which is a normal phenomenon. The engine of the car used to burn gasoline, and the engine failure light will definitely turn on after changing to gas.

There are oxygen sensors around the engine of the car, which are installed in the front and rear of the three-way catalytic converter at the exhaust pipe head.

The oxygen sensor in front of the three-way catalytic converter is used to detect the oxygen content in the exhaust gas, and then the ECU adjusts the air-to-fuel ratio of the engine according to the signal of this oxygen sensor.

The oxygen sensor behind the three-way catalytic converter is mainly used to detect whether the three-way catalytic converter is failing.

If the data transmitted to the ECU by the oxygen sensor before and after the three-way catalytic converter is the same, it means that the three-way catalytic converter is faulty, and the fault light will also be on.

Three-way catalytic converters are used to purify exhaust gases. If this component is not qualified, the content of harmful substances in the exhaust gas emitted by the car will exceed the standard.

If the three-way catalytic converter is damaged, it cannot pass the annual inspection.

Therefore, after the three-way catalytic converter is damaged, it needs to be replaced in time.

When replacing the three-way catalytic converter, it is recommended to choose the original product, which has better reliability and durability.

Oil-to-gas vehicles are modified on the basis of the original gasoline or diesel vehicles, and the fuel system of the original gasoline or diesel vehicles is mostly retained. Therefore, on the basis of the fuel system of the original car, the natural gas fuel system should be added, so the oil-to-gas car carries less fuel, which also increases the weight of the car. The failure light of the oil-to-gas engine is due to the failure of oxygen sensing or the oxygen content in the exhaust gas is too high, which is beyond the control of the car computer.

After the engine oil is changed, the reason why the fault light is on is that the oxygen sensor is faulty, or the oxygen content in the exhaust is too high and has exceeded the adjustment range of the ECU, so the engine fault light will be on, which is a normal phenomenon.

The fault lamp will be on after the oil is changed to gas, because his compression ratio has changed, and the fault lamp cannot be eliminated, unless you say anything? Restore this fuel mode. This gas is always lit up.

Because of this change in compression ratio, this faulty lamp cannot be eliminated, unless you say something? Restore this fuel mode. This gas is always lit up.

When the engine fault light is yellow, the owner should not panic and can check it according to the following methods:

1. Turn off the engine after pulling over, wait for 5 minutes, press the key to start directly without stepping on the clutch or rotate the car key half a circle to the ON position, so that the car is energized, and the car will be self-tested after the power is turned on, and observe whether the fault light on the dashboard is extinguished.

2. Don't worry if the light is still on, because under normal circumstances, the fault light will not go out by itself after it is lit, and then confirm the following situation. After starting the vehicle normally, confirm the state of the vehicle, and there is no obvious change in the shaking and noise sensitivity of the engine compared with the usual world, you can drive normally and choose the nearest repair wide for inspection and repair. If you notice that the jitter is significantly stronger or the noise becomes louder, it is recommended not to continue driving the car and seek help nearby.

As a novice driver, when the engine failure light is on, they will be at a loss and do not know how to deal with it, while the old driver does not care, thinking that it is not a fault and does not take it to heart. However, for the sake of life safety, if there are conditions for maintenance and testing nearby, it is better to choose the nearest maintenance, one is responsible for the safety of its own ruler, and the third is that the engine is in an abnormal working state after the engine fault is lit up, which will cause fuel consumption to increase.

Hello, this is an engine failure to take a round light, first, the cause and solution: poor gasoline quality, not up to standard: it is estimated that most car owners have this calendar, the car refueled not long after, the car dashboard on the engine failure light; This is generally due to the addition of poor quality gasoline at non-standard gas stations, resulting in insufficient combustion of the oil-gas mixture when the engine is working, and the engine failure cavity orange.

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. For faults such as engine failure, the first thing to do is to detect the circuit in the engine starting system. From the perspective of the most basic composition, the mountain distribution circuit of the starting system generally includes the following basic parts, that is, the battery, the starting motor and the cable connecting these components.

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 an EDM detector, it is preferable to have an adjustable detector rather than a fixed design, as it allows you to adjust the detector to a smaller gap so that you can tell if there is no spark at all, or if there is a 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, the yellow light on the dashboard of the vehicle is on, indicating that the engine of the vehicle needs to be maintained or maintained. In case the vehicle breaks down on the road during use, hope, thank you.

Hello, the car needs to be repaired, I hope it can help you.

<> "Reasons for the Yellow Light of the Engine on the Car Dashboard.

There are many types of fault lights on the car dashboard, and once these fault lights are on, then the corresponding parts on the vehicle may fail or be abnormal. So what's the deal with the yellow light on the engine of a car dashboard?

If you find that the yellow light of the engine is displayed on the dashboard, it happens to happen after the vehicle is just turned on the power supply, and it will automatically turn off after a while, which is a normal situation, the owner does not have to worry too much, it belongs to the system is completing the vehicle self-test, not that the engine is faulty.

If it is found that the engine lights up yellow and does not go out, it means that the engine is faulty, and the cause of the engine failure needs to be investigated in time, which is likely to be the damage of the three-way catalytic converter, which causes the engine fault light to turn on.

If the spark plug and fire coil are used for a long time, there will also be a fault, and the engine will not work properly, so a yellow light will be lit to alert the owner.

When the oil circuit is blocked, the gasoline can be fully burned, and the engine does not have enough power, so the fault light will also be lit, and it should also be noted that if the wrong gasoline is added or the quality of the gasoline is not good, it will also lead to this situation.

When the car engine turns on the yellow light, the owner's first reaction is to destroy the fiber as soon as possible for inspection and repair, so as to ensure the normal use of the vehicle in the later stage.

Summary. Hello dear, the yellow light on the dashboard engine is indicated after the gas change is because the first one is that when we turn on the power of the car, the car will perform a self-test. At this time, not only the yellow light of the engine will turn on, but the other fault lights will also turn on and go off together.

This is normal. Second, after the car starts, the yellow light of engine failure is still on, and the ECU is reminding you that the engine is faulty.

Hello dear, after the gas change, the engine on the dashboard is marked with a yellow light because the first one is that when we turn on the power of the car, the car will perform a self-test. At this time, not only the yellow light of the Sakura engine will turn on, but the other fault lights will also turn on and go off together. This is the phenomenon of the destruction of the normal in the spring.

Second, after the car starts, the yellow light of engine failure is still on, and the ECU is reminding you that the engine is faulty.

It is the Santana automatic transmission after the yellow light is on, and it can drive normally. How to fix it.

Hello, the yellow light indicates that the engine is faulty, but the fault does not affect the normal operation of the engine, but it must be tested and repaired.
