What does it mean when the Suzuki Alto fault light is on

The engine is not in a good burning state, or the engine is knocking.

First, the combustion state is not good.

Oxygen sensors are installed on the engine to detect the combustion state of the engine, once the combustion state of the engine is not good, such as the hydrocarbon gas (HC) content is too high, the carbon monoxide (CO) content is too high, and the carbon oxide (NO) content is too high, these are all bad combustion states, which not only pollute the environment but also cause fuel waste and excessive wear and tear of the engine.

Hydrocarbons (HC): Unburned fuel components.

Carbon monoxide (CO): An inadequately burned fuel component that can cause poisoning and death.

Nitrogen oxides (NO): Produced at high temperatures in the engine, indicating increased engine wear.

Second, the engine knocks.

There is also a knock sensor on the engine to detect engine knocking, which already means that there is a risk of serious mechanical damage or loss of power to the transmitter.

There are three subjective feelings of the car driver about the knocking: 1. The car is weak 2. The car is weak and the engine noise is too loud 3. There is obviously a cylinder knocking sound. In the first case, the fault light will sometimes turn on, but in the second and third cases, the fault light will inevitably turn on.

Hello owner, there are many reasons for the engine failure light to be lit, when the instrument shows this yellow engine fault light, it means that there is a problem with your car, the body has more than 10 sensors, these more than 10 sensors will cause the fault light to light up, so only with computer detection can you know that it is caused by a problem, so now there is no way to give you an accurate answer, it is recommended that you go to the nearest repair shop to test, I hope it can help you, I wish you a happy car [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The engine fault light is on, but there is no abnormality in driving, it may just be a sensor failure, you can continue driving temporarily, but it is best to slow down at medium and low speeds, and go to 4s for maintenance as soon as possible. If the vehicle is in the normal driving process, the engine fault light is on, it is recommended to stop safely, turn off the engine and cut off the power, wait for a while, restart to see, if after restarting, the engine fault light on the dashboard is off, then it is likely to be the quality of the fuel, try to choose to fill the fuel at a regular gas station, if the engine fault light on the dashboard is still there and the potato is there, you need to see whether the oil alarm light and water temperature warning light are on the dashboard, if the oil alarm light and the water temperature warning light are lit at the same time, If there is only an engine fault light on the dashboard, then the vehicle can continue to drive, as soon as possible to the nearest auto repair shop or 4S shop to read the fault, judge the fault point, 1. The sensor includes 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, which will cause the engine fault light to turn on. 2. Poor engine maintenance is the most common cause of engine failure.

Vehicles have 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 be reminded by the fault light. 3. Oil quality includes fuel and engine oil, the fuel filled by the car is generally marked, and the manufacturer generally recommends the owner to use which grade of fuel, which type of engine oil, if the owner does not add it as required, it will call the police in the long run. There are many reasons why the engine fault light is lit, when the instrument shows this yellow engine fault light, it means that there is a problem with your car, there are more than 10 sensors in the body, these more than 10 sensors will cause the fault light to light up, there may be an oxygen sensor, or it may just be a simple error, so only by using the computer to detect can you know that it is caused by the ** problem with the shed file, so now there is no way to give you an accurate answer, it is recommended that you go to the nearest repair shop to test it.

At the moment, if everything is fine when driving and accelerating, it means that the gasoline you added is not of good quality.

The car is not powered enough and does not turn on the fault light, and the reasons for this failure are nothing more than the following aspects.

1. The three-way catalytic converter of the exhaust system is blocked.

In the process of long-term use of the car, due to the fact that some dust impurities will be produced in the combustion process of the fuel, not the engine can be completely discharged through the three-way catalytic converter after each work, and the three-way catalytic converter will be blocked to varying degrees after a long time.

After the three-way catalytic converter is blocked, it is easy to cause faults such as engine power decline, slow speed, and excessive tail hair.

What to do after this phenomenon occurs:

It is recommended to clean the ternary or replace it with a new one.

2. Gasoline pump failure.

Gasoline pumps are electronic products and also have a service life. In the process of long-term use, it will cause its internal components to wear out, and the speed will decrease, resulting in a decrease in fuel system pressure during operation. Because it cannot meet the fuel pressure demand of the engine under different working conditions, it can not accelerate sharply or show insufficient power when driving.

Solution: It is recommended to replace the petrol pump with a new one.

3. Clutch slippage (manual transmission car).

When the clutch shifts gears during the start of the vehicle and during driving, the engine power and the power transmission of the transmission shaft will be cut, so that the gear mechanism in the gearbox can smoothly change gears. When driving, the clutch and the gearbox one shaft are transmitted at equal speed again, when the clutch slips, the engine power can not be transmitted to the gearbox one shaft early, resulting in the engine speed slow, insufficient power and other fault phenomena.

This can be found in the manual, and we have found this problem before, so we looked it up. Personally, I don't think it's necessary to delete it, and I can often remind myself to maintain it.

One: You can pull out the fuse to clear the fault code, if it can't be solved, go to the maintenance unit to use the decoder to clear the fault code to see, if you can't clear it, it needs to be repaired.

2: Generally, the decoder is used to clear the fault code, and some units will charge a small labor fee.

Three: The engine is a machine that converts a certain form of energy into mechanical energy. Its function is to convert the chemical energy of liquid or gas into heat energy after combustion, and then convert the heat energy into mechanical energy through expansion and output power.

The power of the car comes from the engine. According to the different fuels used, common engines can be divided into gasoline engines (referred to as gasoline engines) and diesel engines (referred to as diesel engines). Gasoline engines are fueled by gasoline, and diesel engines are fueled by diesel.

Core tip: The diagnosis and elimination method of the oil pressure warning light is always on is as follows: 1) First unplug the wire on the oil pressure switch, if the oil pressure warning light is off, it means that the fault is caused by the oil pressure.

The diagnosis and elimination methods for the oil pressure warning light to be on are as follows:

1) First unplug the wire on the oil pressure switch, if the oil pressure warning light goes out, it means that the fault is caused by the oil pressure or oil pressure switch; If the oil pressure warning light is still on, the fault is from the oil pressure warning light line or gauge.

2) If the fault is caused by the oil pressure or the oil pressure switch, then you should check whether the oil pressure is normal first. If it is normal, the cause of the fault is the oil pressure switch, at this time, you can replace a good oil pressure switch and then check; If the oil pressure is incorrect, the engine's lubrication system should be checked.
