Santana Zhijun EPC Liang can t be oiled

First of all, your car has entered the emergency function. Under normal circumstances, if the engine speed exceeds 1300 rpm, the engine computer will use the brake signal to control the oil cut-off, which is energy-saving and environmentally friendly. At this time, if you press the brakes, the computer will prevent the engine from stalling and control the increase in speed.

It is normal to focus on checking the accelerator pedal position sensor and the wiring between it and the computer, and the throttle valve is not to be considered. The EPC light should be on, and it is better to use the instrument to measure the fault code, which is more direct. EPC is an electronic throttle system.

The computer detects the engine control unit fault storage, checks the throttle position sensor and accelerator pedal position sensor as well as the wiring and plug, and replaces if necessary.

The accelerator pedal sensor is faulty.

PowerControl, which stands for Electronic Engine Stability System, is also known as the Electronic Throttle Valve. If the vehicle does not turn off after starting, it means that the vehicle's mechanical and electronic systems are malfunctioning. Generally speaking, there are two possibilities for the EPC light to be on, one is that the throttle valve is dirty and should be cleaned.

Another situation is that the brake light is not on, and you need to check the brake switch as well as the wiring.

Also, due to oil problems, the EPC faulty lamp will also be lit.

The car EPC light is on, indicating that there is a problem with the vehicle, and it is recommended to go to the 4S store for inspection as soon as possible!

Summary. Hello, I am your exclusive elite technician, we promise to be attentive, careful, and attentive to answer your car questions. Hello, this Volkswagen Santana fuel gauge will not move, the reasons are as follows: the first is that the oil float in the fuel tank is stuck, the second is that the instrument is damaged, and the third is that there is a problem with the line between the rod and the instrument.

Look at the fuel gauge pointer to see if there is any response, if there is no response, that section is damaged by floats.

The oil pump and gauge were replaced. The line from the oil pump to the meter was also fine. What is the reason for that?

Hello, I am your exclusive elite technician, we promise to use the palm of your hand, careful, and concentrate on answering your car questions. Hello, this Volkswagen Santana fuel gauge will not move, the reasons are as follows: the first is that the oil float in the fuel tank is stuck, the second ruler is the hole is the instrument is damaged, the third is that there is a problem with the line between the rod and the instrument, after this situation is dry, it is recommended that you first disassemble the oil pump and manually dial the float! Look at the fuel gauge pointer to see if there is any response, if there is no response, that section is damaged by floats.

I found the line from the oil pump directly from the gauge. The voltage is all the same.

The line of the fuel gauge pointer, it is not the voltage he is resistor. You can't measure the voltage.

I feasted on a thin oil float on the oil pump. The voltage measured on the meter is the same. Doesn't that mean that the line is fine? Then I took a picture and got a meter. In the test attack, the orange test still doesn't work.

The line between the pointer of the fuel gauge and the gauge has no voltage, it is a resistor.

I know. It's the resistor that shoots the gods. It's all the same raider. Now the key oil pump will not work. If it's okay. Isn't the oil pump going to work for a while?

Didn't you say that the fuel gauge hands don't move? What exactly is your problem now? Is the fuel gauge not working? Or is the oil pump not working?

Pointer. If the pointer of the fuel gauge is not accurate, you have to measure whether the float can be passed between the meter and the meter, you can't measure the voltage, and you need to use the on-off file of the multimeter to measure it.

Isn't it a resistance gear?

No, the on-off file test line is on/off.

Most of the time it's the two brake lights that are broken. Then there is the problem with the brake switch. If the EPC alarms, everything is normal when the car is driven, and the brake light is basically determined. The car is weak to drive, and there is a problem with the brake switch. Because of the throttle, the possibility of an alarm is very small!

What's the matter with the Santana EPC light not oiling? What's the matter with the Santana EPC light not oiling? The following are the reasons and solutions for the Santana EPC light to not be oiled:

1. The throttle body is too dirty: the fault caused by the throttle body is too dirty. In this case, the throttle valve can be cleaned and then rematched.

2. Air intake system failure: There is a leak in the air intake system, which causes the engine control unit to light up the EPC warning light after detecting the problem. Replacing the air intake system parts with new ones will solve the problem.

3. Brake light switch failure: Brake light switch failure. Replace the brake light switch with a new one, and check the brake system for faults in time.

Only normal oil pressure can ensure that the oil is delivered to all friction surfaces of the engine, too high or too low will affect the normal operation of the engine, and even cause damage to engine parts. Therefore, when the oil lamp alarms, it should be stopped immediately to find the cause, and the work can be continued only after the fault is eliminated. The following reasons may cause the oil lamp to alarm:

1.The oil volume of the engine oil is insufficient, so that the oil volume of the oil pump is reduced or the oil cannot be pumped due to air intake, resulting in the oil pressure dropping;

2.If the engine temperature is too high, it is easy to thin the oil, and a large amount of oil pressure will be lost from the mating gap, resulting in a drop in oil pressure;

3.When the oil pump parts are damaged or the gap is too large due to wear and assembly, it will cause the failure of the oil pump not producing oil or insufficient oil output;

4.The fitting gap between the crankshaft and the large and small tiles is improper, too tight will increase the oil pressure, and too loose will reduce the oil pressure;

5.Blockage of oil filters and suction discs will also reduce oil pressure;

6.Damage or failure of the oil return valve: If the spring fatigue of the oil return valve of the main oil channel is softened or improperly adjusted, and the mating surface of the valve seat and the steel ball is worn or stuck by dirt and closed tightly, the oil return volume will increase significantly, and the oil pressure of the main oil channel will also decrease;

7.Improper selection of engine oil: If the wrong oil or grade is not selected properly, the leakage will increase due to the low viscosity of the engine oil when the engine is running, so that the oil pressure will be reduced;

8.There is oil leakage and blockage in the oil pipeline;

The oil pressure is insufficient, and the speed goes up, and the pressure goes up without flashing. Please repair it in time
