Where is the Great Wall Wingle 5 oil induction plug

Hello This is the oil light on caused by the low oil pressure, it is recommended to check whether the oil volume is too low or the oil pump is depressurized. It is also possible that the oil pressure sensor is faulty, or the oil pressure sensor line is shorted to ground.

Generally behind the engine, on the cylinder block, next to the oil filter cartridge seat. There is a plug with a wire on it, which is located on the front oil duct of the oil filter.

The electronic oil pressure sensor consists of a thick film pressure sensor chip, a signal processing circuit, a housing, a fixed circuit board device, and two leads. The signal processing circuit is composed of a power supply circuit, a sensor compensation circuit, a zeroing circuit, a voltage amplification circuit, a current amplification circuit, a filter circuit and an alarm circuit.

Figure 1 is a structural diagram of the sensor, and Figure 2 is a block diagram of the sensor. The thick film pressure sensor is a new type of strain pressure sensor that appeared in the 80s of the 20th century, which is developed by using the piezoresistive effect of the thick film resistance printed and sintered on the ceramic elastomer. Four thick film resistors are directly printed and sintered on a ceramic elastic diaphragm and connected to form a Wheatstone bridge through a conduction belt.

When the measured liquid level pressure acts on the ceramic elastomer, the elastic diaphragm produces deflection deformation, and at the same time, the thick film resistance imprinted on the elastic diaphragm also produces strain of the same magnitude, and the resistance value of two thick film resistors decreases under compressive strain. The other 2 tensile strains increase the resistance value. In this way, the measured pressure value is converted into a bridge output signal, and the signal size is proportional to the pressure.

The position of the Great Wall Fengjun 5 diesel filter next to the battery of the car can be seen by looking closely at the battery.

Diesel filters filter out solid impurities (iron oxide, dust, etc.) contained in the fuel, so as to protect the oil pump nozzle, cylinder liner and piston ring, which can not only greatly reduce wear, but also avoid clogging.

Don't underestimate the role of diesel filter, you should know that the sulfur content of domestic diesel is very high, if there is no diesel filter, the sulfur element will directly react with water to form sulfuric acid, thereby corroding the internal parts of the engine. Therefore, the diesel filter is extremely important (the water outlet method is mainly sedimentation).

Extended information: The introduction of the Great Wall Wingle 5 diesel filter is as follows:

If the diesel filter element is very dirty, there is definitely no way to ensure that the fuel is clean when it enters the engine cylinder for combustion, not only the power of the car will seriously decline, but it will even affect the service life of some parts (sulfur and water reaction are disassembled into sulfuric acid), and the maintenance cost can be said to be quite high.

Therefore, when it is found that the color of the filter element in the diesel filter has turned significantly black, it means that the filter element is seriously polluted by harmful substances and needs to be replaced in time. Next to the oil pump.

An oil filter, also known as an oil grid. It is used to remove impurities such as dust, metal particles, carbon precipitates and soot particles in the engine oil and protect the engine.

The Great Wall Wingle 5 looks at the oil dipstick method as follows:

First of all, if the car is in a driving state, park the car at this time, turn off the engine and wait for about 10 minutes, which means that all the oil will flow back to the oil pan. At this time, pull out the oil dipstick, first use a clean cloth to wipe off the original oil stains on the oil dipstick, and then insert the oil dipstick back to the bottom, and pull out the oil dipstick again after a few seconds to measure the accurate oil level height.

At the end of the dipstick there is the upper and lower limit markings, observe the part that is soaked by the oil, if between the upper and lower limits, it means that the oil volume is just right, if it is higher than the upper limit, it means that the oil volume is too much, and if it is lower than the lower limit, it means that the oil volume is too little, and it needs to be added in an appropriate amount.

Open the engine compartment cover and pull out the dipstick to see if there are any oil stains between the bottommost tick marks.

The dipstick has two horizontal lines or two round holes in the middle position, and it is not lower than the lowest line.
