The SVS indicator is a fault indicator for all electronic faults.
The SVS fault light is a fault light when an EFI car's ECU computer or TCU computer detects a problem with the engine or automatic transmission.
So as long as the EFI car is equipped with an SVS trouble light, the manual transmission has the engine trouble light and the automatic transmission has the engine and automatic transmission trouble lights.
Causes why the fault indicator lights up
1. The combustion condition is not good.
2. Fuel quality is not good.
3. The inside of the engine cylinder is dirty and contains carbon deposits.
Detailed information

Why is the Mustang engine so loud?
1. The combustible mixture is too rich. The partsRemaining unburned fuel will accumulate on the spark plug electrode and be carbonized, causing the spark plug to flash abnormally until it is damaged by carbonization. The reasons for the fuel mixture being too rich are usually that the carburetor oil level is too high, the carburetor main air volume hole is clogged, and the air filter element is seriously clogged. Additionally, the carburetor choke is blocked and cannot be fully opened, or the enrichment valve is not working properly, which is also the reason why the fuel mixture is too rich.
2. Engine oil leak. During engine operation, if blue or black smoke is emitted from the exhaust pipe, this indicates that excess engine oil has entered the cylinder, which will cause a large amount of deposits to be produced of carbon by the electrodee of the spark plug or its humidification. by engine oil and unable to produce sparks. This phenomenon is commonly referred to as engine oil channeling. For two-stroke engines, check whether the oil volume of the oil pump is too large and whether the rod sleeve seal and check valve are defective. For four-stroke engines, check the piston rings on the piston, especially the oil ring, whether it is worn or not. Then remove the intake valve and check for carbon and wet grease deposits on its head and back. If the valve and valve guide are severely worn, the valve guide seal is hardened, or the seal lip is excessively worn, the mounting gap will be too large and the effect of The seal will be lost. Both of these abnormal situations will eventually cause oil to be drawn into the valve rocker arm chamber into the cylinder the long of the valve stem during intake air summing, causing oil combustion. In this regard, the valve guide, oil seal or valve must be replaced respectively depending on their wear.
3. In the ignition system, the magneto is demagnetized, the wire connections inside the ignition coil and the electronic ignition, the generator output end and the coil input end are demagnetized. The ignition is loose and the ignition timing is incorrect. If it is not properly timed, it will affect the ignition performance, and poor ignition performance will directly cause carbon deposits.
4. Pay attention that the spark plug model and calorific value comply with the instructions for use. If the selected calorific value is one or two ratios lower than that specified in the instruction manual, the heat cannot bere dissipated in time, causing abnormal combustion and eventually melting the spark plug electrode and causing premature damage. When the spark plug itself is installed and used, some defects are not easy to find and also affect the ignition performance. For example, if the spark plug is poorly sealed, if the spark plug is not firmly fixed, if the spark plug insulator is cracked, etc., it should be adjusted or replaced in time . 5. If the crankcase oil is overfilled and the breather pipe is blocked, the pressure in the crankcase will increase and the crankcase will not be balanced.
Analysis of the specific reasons for loud engine noise:
1. When I stepped on the accelerator, I found that the acceleration was not obvious, there was a lack of power, and the engine made a noise. its hysterical. The times most likely to occur arewhen the engine is hot or cold, or when it is low on oil. The causes of these problems can be divided into air filter, spark plug, ignition wire, gasoline, fuel filter, carburetor, oil pump and other problems. Check if the air filter is dirty, if the spark plug is old and needs to be replaced, if the ignition coil is broken, and if the gasoline is not clean, such as water in the fuel line. 'oil. Also check the oil pump.
2. When driving, acceleration is normal and ignition may be normal. However, when driving at a constant speed, it is found that the engine speed is too high but the speed still cannot be increased. Try checking the coolant. Oil pressure is too high or too low. Check the pressure gauge. There may be a problem with the ignition time setting, which may also cause such symptoms. As with others, itIt could be a problem internal to the engine, such as a clogged EGR valve.
3. The motor makes a whistling sound, which sounds like steam or air coming out of the motor. Typically, after hearing this sound, the engine will quickly lose power. Possible problem, engine overheats, check cooling system. The exhaust system is clogged, the suction pipe is leaking or broken.
4. When accelerating, the engine will make a whirring sound, or it will also appear when decelerating. In short, the sound will change as the regime changes. The possible reason is lack of power steering oil, fill it up. The generator bearings could be damaged. Problems with the power steering pump and water pump will produce similar noises.
5. A very loud noise comes from the exhaust pipe, which is very annoying. Sometimes a similar noise comes from the front. The main problemis the exhaust system. Check if the exhaust pipe is broken.
6. When the motor is running, it makes a clicking sound, as if something is hitting metal. When accelerating or driving, you may not hear anything. This may be caused by the cylinder valve, which can be changed by adjusting the valve. Lack of engine oil can also cause similar problems and engine oil pressure is relatively low. Check the engine oil pressure.
7. When you press the gas pedal, you will hear a clicking noise coming from the exhaust pipe. The sound may not be very loud and the car will not run abnormally, as well as fuel consumption. will increase. It is recommended to check the muffler and exhaust pipe for damage.
8. The motor makes a kicking sound, like the sound of a pencil hitting the table. The sound increases whenthe engine speed increases. The possible cause is that there is dirt inside the engine. It is recommended to change the oil, filter and clean the engine. Others may be a valve problem.
9. There may be no problem while driving, but there will be a clicking noise when accelerating. It is recommended to check the ignition time setting. The engine may overheat, the engine may have carbon deposits. or the oil quality is not good.
10. High-pitched noise, obvious as a squeak. Possible reasons are that the drive belt is slipping and the driving direction is too high, reaching the limit. The belt is too loose, tightening the belt may solve the problem.
11,When driving at low speed or accelerating with the gas pedal, you will hear a “kronk”-like noise under the engine, especially when the weather is colder.ais. Build
