After the car flooded, all the fault lights came on. What happened?
2. Too much carbon deposit in throttle, idle motor, air intake and combustion chamber will lead to engine flameout. There are too many carbon deposits and dirt in the air inlet, and the cross-sectional area of the air passage changes, which makes the control unit unable to accurately control the idle air intake, resulting in the mixture being too rich or too thin, which leads to the failure of the engine to start, and the instrument panel fault light is completely lit.
3. Due to the poor performance of maintaining constant pressure of fuel in the electronic control system, the fuel pressure is low, the fuel injection atomization is poor, and it is difficult to start, which leads to the failure light on the instrument panel.
There are generally three situations when the car stops and water enters. In the first case, if you call the trailer to send it to the repair shop in time, it can still be recovered if it is cleaned properly; The second is that the car enters the water while driving, as long as it is restarted after the flameout does not stop;
Third, there is a lot of water in the engine cylinder, the crankshaft can't turn, and the starter doesn't work. Even if you turn on the ignition switch, the vehicle can't start. There is a risk of overhaul in this situation.
In fact, the most worrying thing about car water intake is engine water intake. We can judge whether the engine is flooded by the following symptoms:
1, check the oil status.
Normal oil color is light yellow, brown, transparent and colorless, but generally it will not be milky white. Pull out the dipstick, clean it before putting it in, and check whether there is emulsion oil-water mixture. If there is, there may be water in the engine.
2. Check the air filter
Check the air filter and the lower shell of the air filter for obvious water inlet traces, and check the air inlet pipe and intake manifold for obvious water inlet traces. The owner can DIY remove the air filter.
