Dongfeng Tianlong 420 horsepower rail voltage fault 523613 15 and STOP red light on what is the faul

The failure of the horsepower rail pressure is carbon deposit, and the stop red light is the failure of the throttle.

Car carbon deposition requires users to replace qualified engine oil, and replace it regularly, throttle failure can be scrubbed with throttle cleaner, if the throttle has been damaged, it needs to be replaced, so as not to affect driving.

Carbon deposits can cause insufficient combustion of gasoline and cause the engine to shake. The first is to reduce the engine power, that is, to make the power output uneven and gradually decay, increase fuel consumption, and increase the economic burden. It is difficult to start cold, that is, it is difficult to ignite, and it is not easy to get on the car, which causes damage to the piston and crankshaft, causes high engine temperature and seriously affects the safety of the car.

Then there is the excessive discharge, which not only fails the annual inspection and inspection, but also directly aggravates the harm of polluting the environment.

The throttle valve is faulty. Both of these problems can cause engine shake and unstable speed.

It's just that there is no oil, fill up the oil, and the fault code will naturally disappear from the new start.

The rail pressure of the common rail engine is abnormal, which is manifested as too high or too low. Too high is generally a problem of low pressure oil circuit, check the lower oil inlet pipe, extension pipe, oil-water separator and diesel filter.

1. Lift the vehicle to find the gasoline filter. The details are shown in the following figure:

2. Pull out the gasoline filter. The details are shown in the following figure:

3. Disconnect the filter element pipeline. The details are shown in the following figure:

4. Install the filter element in place to complete. The details are shown in the following figure:

Mine is a Renault 385 and this morning I had this kind of situation, but there was no adverse reaction, I don't know if there was a problem.

Summary. If this fault code appears, it is generally because your rail pressure is abnormal, this is mainly due to two reasons, on the one hand, because your oil pressure causes the vehicle to be unable to obtain the actual fuel pressure, if it can be recovered after restarting, then most of the oil pressure sensor is broken, you can consider directly replacing an oil pressure sensor. If you can't recover after restarting, then most of the reason is that your high-pressure oil pump is broken, and you need to consider replacing the high-pressure oil pump.

Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.

Summary. Hello, glad to answer for you. Dongfeng Tianlong 420 horsepower rail pressure failure and stop red light is engine coolant failure.

Engine coolant is mainly made from a mixture of ethylene glycol and water in a certain ratio, with some rust inhibitors added. To prevent freezing in cold weather, engine coolant has a much lower freezing point than water. A good engine coolant protects the cooling system from rust or corrosion.

Hello, I am inquiring for you here, please wait a while, I will reply to you immediately Hello, I am very happy to answer for you. Dongfeng Tianlong 420 horsepower rail pressure failure and stop red light is engine coolant failure. Kailiang engine coolant is mainly made of ethylene glycol and water mixed in a certain ratio, and some rust inhibitors are also added.

In order to prevent freezing when the weather is pure Sunbu, the freezing point of the engine coolant is much lower than that of water. A good engine coolant protects the cooling system from rust or corrosion.

Summary. Hello, dear, Dongfeng Tianlong rail voltage fault code fault light when the car is refueled and the power is off and the normal reason is carbon deposit. Carbon deposition will cause the steam to hold the oil and burn inadequately, so that the engine will shake.

The impact of engine carbon deposition on the car is quite large, first of all, to reduce the engine power, that is, to make the power output uneven and gradually decay, in other words, more and more powerless.

Hello, dear, Dongfeng Tianlong is stupid, the rail voltage fault code, the fault light is on, the car is refueled, and the power is off and the restart is normal, and the reason is carbon deposit. Carbon deposition will cause the steam to hold the oil inadequately combustion, so that the engine will be accompanied by the problem of shaking. The impact of engine carbon deposition on the car is quite large, first of all, to reduce the engine power, that is, to make the power output uneven and gradually decay, in other words, more and more powerless.

Replacing the grease nipple and the metering unit valve still shows the fault.

The second is to increase fuel consumption and increase the economic burden. The third is the difficulty of cold start, that is, the difficulty of ignition, it is not easy to get on the car, and finally the carbon deposition in the combustion chamber will also cause cylinder detonation, and the acceleration at low speed will cause damage to the piston and crankshaft, causing high temperature of the engine and seriously affecting the car Anyan.

Have you checked the diesel filter?

Also changed. Rail pressure failure is an abnormal rail pressure.

The P0190, P0191, P0192, P0193 and P0194 are the most common fault codes indicating the fault of the track pressure sensor.

Be. The low pressure of the oil rail refers to the reasons for the slag: 1. The oil circuit is blocked or there is too much moisture in the oil, resulting in low pressure of the oil rail; 2. The nozzles of all cylinders are connected to a common oil pipe, there is always a constant pressure in the guide rail, the fuel guide rail remains basically unchanged in the whole injection process, and is free to choose independently of the speed and load of the engine, if the beam is damaged, it will lead to low pressure of the oil rail; 3. If the injector is blocked and damaged, it will also cause the low pressure of the oil rail.

Weiqiao high-pressure fuel rail, used to store fuel, while suppressing the pressure fluctuation caused by high-pressure pump fuel supply and injector fuel injection, to ensure that the system pressure is stable, high-pressure oil rail is owned by all cylinders, which is the symbol of the common rail system.

You check that the lower oil circuit is not blocked.

Summary. Hello, dear, Dongfeng Tianlong KL465 Longqing National VI, in addition to the fault code report and , the reason for the torque limit is caused by the failure of the urea pump. Fault code 3361 refers to the crankshaft position, and the camshaft position correlation has failed.

The function of the crankshaft is to turn the up and down motion of the piston into a rotary motion. The role of the camshaft is to control the opening and closing of the valves. The electronic control unit (ECU) continuously monitors the timing position of the variable camshaft.

Check the relative position between the camshaft and crankshaft, if the relative position is misaligned beyond one tooth, the fault code will appear.

Hello, dear, Dongfeng Tianlong KL465 Longqing National VI, in addition to the fault code report and, the reason for the torsion is also caused by the failure of the urea car pump. Fault code 3361 refers to the crankshaft position, and the camshaft position correlation has failed. The function of the crankshaft is to turn the up and down motion of the piston into a rotary motion.

The function of the camshaft is to control the opening and closing of the valve clam. The electronic control unit (ECU) continuously monitors the timing position of the variable camshaft. Check the relative position between the camshaft and the crankshaft, if the relative position is misaligned beyond one tooth, the fault code will appear.

The reason for the fault code is the failure of the urea pump, and the inspection process is: 1. Check whether the contact between the post-processing line Zen and the sensor is normal, and if there is a problem, adjust and repair it in time; 2. Check whether the urea pipeline is cleared and whether there is any leakage, and if so, it needs to be replaced in time; 3. Check whether the urea pump is working normally, once the abnormal work is found, check the cause of the failure in time; 4. Check whether the urine fiber nozzle is working normally, if the nozzle is found to be blocked or cannot be opened normally, it should be cleaned or replaced in time.

Dear, you can just change to a urea pump.
