Car repair of hot car does not start fault

Today we came across a strange problem with this car, the owner said that it can only start every morning, after starting, it dare not turn off the engine, once it turns off, it can never start again, only until the next morning can it restart. Let's try it, it's starting now, the water temperature is normal,

I'm turning off the engine now, let's try to start it, it won't work for several times in a row, do you know what's the reason? This problem has been plaguing the owner for half a month. I've been to several garages, changed the spark plugs, washed the throttle, changed the oil, changed the fuel pump and spent more than 2,000 yuan, but the problem is still not solved. Today I'll see if I can fix this problem, which is typical of a cold car that starts easily and a hot car that doesn't start well. This fault is related to the engine temperature, generally speaking, it is the water temperature sensor is bad, this sensor is based on the engine temperature to control the amount of fuel injection, if he is bad, then this problem will occur, but after I check this sensor so new, obviously the owner has been replaced outside,

so that the problem is certainly not here. In fact, in addition to the water temperature sensor, there is a sensor, but also with the engine temperature control, and many repair shops are easy to ignore, is this intake air temperature sensor, we take it out to see, dismantling it is particularly simple, it does not have screws, there is a snap, to it can be taken out,

and then this plug to it unplugged, the cause of the problem found to, you see this The sensor head is full of sludge, you see the sensor head inside are wrapped, no wonder it is not easy to start ah, find the cause of the problem, the solution is not simple, find a bottle of detergent, the above sludge to clean it, you see how dirty, the sensor is used to detect the air intake, the sensor is used to detect the air intake. This sensor is used to detect the temperature of the air intake, if he is too dirty,

the computer does not receive the correct temperature signal, it will affect the amount of fuel injection, so when the car is hot, it is not good to start.

After cleaning, we will install the car to see the effect, the installation is particularly simple, the sensor aligned with the hole,

press the inside, and then plug back in, well this is installed, then I will start to try, open the key door, and then a start, now the engine is not cold, we test a few more times, are a start, the engine runs particularly smooth, the problem has been completely solved The problem has been completely solved, how is it not particularly easy to repair a car with your own hands.
