This is prone to poor contact, mostly due to damage to the plating or poor working environment. It is recommended to replace the harness connector.
A visual inspection should be carried out before replacement. The new wiring harness model should be consistent with the original model with wire terminals.
The connection with the wire is reliable, and the connector and the wire can be pulled by hand to see if there is any loosening or falling off. Compare the new wiring harness with the original wiring harness, such as: the size of the wiring harness, the wire terminal joint, the wire color, etc. should be basically the same. If in doubt, a multimeter can be used.
Perform a test to confirm that the wiring harness is in good condition before replacement.
In addition, if the parts are not very serious or necessary, you can dispose of them yourself to reduce the cost.
There are several ways to deal with it in general:
1.Many people will use toothpaste to wipe it. There is an effect, but it is easy to sharpen the plug, the expensive earbud plug, please use it with caution.
2.Wipe with a paper towel and vinegar for 5 minutes, the oxidation on the plug will also fall off, and there will also be some traces of flowers on the plug.
3.Oxalic acid. i.e. adipic acid.
It can be used to remove rust. However, be careful when using, oxalic acid is highly corrosive to stainless steel. High concentrations of oxalic acid also tend to corrode hands. and the solubility of the acid oxalate generated.
Large, but somewhat toxic. When using, just don't eat or drink. **After contact with oxalic acid, it should be washed with water in time.
Method: Buy a bottle of oxalic acid from a store selling chemical reagents, take some, prepare a solution with warm water, apply it to the rust stain and wipe it. Then wipe it with metallographic sandpaper and finally spray paint (excerpt from the forum presentation).
4.With polishing paste, you can also solve the problem, for gold-plated plugs, you need to use caution, the gold-plated layer is thin.
WD-40 is used to wash capacitor circuit boards without pressure, and is for mountain bikes.
For washing the chain, it can be polished or cleaned with weak acid, and it must be wiped clean when used, otherwise it will corrode the plug.
6.Arc extinguishing is commonly used in TV, and electronic accessories are available in the market.
7.Rub it with dermathery, without any additives.
If you are not at ease, you can find a car repair shop and let a professional job think that it will work for you, and it will not cost a lot of money if you don't need to replace it.

Automotive connectors are commonly referred to as plugs and sockets, which are used for the interconnection between sensors, actuators, control units and wiring harnesses, wiring harnesses and wiring harnesses, or wires and wires, so that they constitute a complete electrical system. In order to prevent the connector from disengaging while the car is moving, all connectors are latched.
In this way, if the connector is oxidized, it is better to replace it as soon as possible.
So now let's take a look at the overhaul method of the connector.
When checking the voltage or conduction of the line, it is generally not necessary to disconnect the connector, but only use the two meter pins of the multimeter to insert into the wire hole at the end of the connector for inspection.
Overhaul of common connectors
If you need to replace the wire or remove the connector terminal during the repair, the plug and socket should be separated first. Insert a special tool (or a small screwdriver) into the wire hole at the end of the plug or socket, pry the locking flange of the terminal block, and pull the wire out of the rear end.
Before installing the new terminal block, first check whether the locking flange of the terminal block is normal, if it is abnormal, you can directly plug the protruding part into it for adjustment.
To install, push the wire with the terminal block in until the terminal is locked, and then pull the wire back to confirm that it is locked.
Access with locking wedge connector
Pull out the locking wedge directly with needle-nose pliers.
Use a special tool to remove the cleat from the stylus, loosen the cleat and pull out the wire.
Intercept about 120mm wires and terminals, and peel off the 6mm insulation layer.
Insert the bare wire into the butt connector and press the wire tightly with crimping pliers.
Insert the heat shrink tubing into the repair area of the wire, and heat the shrinkable heat shrink tubing with a heat gun.
Reinsert the wires and terminals into the connector and install the locking wedge in place.

The method of oxidation at the joint of the car battery is to pour the oxidized place with boiling water, and the corrosive substance can be removed.
Then remove the battery connector, pour it clean, wipe the water, and then coat the battery head and terminal with a layer of butter and then install it, so that the battery connector will not oxidize again.
The car battery is a device that converts the slag university energy into electrical energy, which belongs to the DC power supply, and its functions are:
1. When starting the engine, provide a strong starting current (about 10A) to the starter.
2. When the generator is overloaded, it can assist the generator to supply power to the electrical equipment.
3. When the engine is idling, supply power to electrical equipment. Stove erection.
4. The battery is also a large-capacity capacitor, which can protect the electrical appliances of the car.
5. When the voltage at the generator end is higher than the electromotive force of the lead-acid battery, a part of the electrical energy is converted into chemical energy and stored, that is, it is charged.

1. Method:
Pour it off with boiling water, wipe it off and apply butter so it won't rust.
Second, the battery, also called the battery, the battery is a kind of battery, its working principle is to convert chemical energy into electrical energy. Usually, people refer to batteries as lead-acid batteries. That is, a battery mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution.
There are two types of oxygen sensors in practical applications: zirconia oxygen sensor and titanium oxide oxygen sensor. The common oxygen sensor is divided into single lead, double lead and three leads; The single-lead one is a zirconia oxygen sensor; The two-lead is a titanium oxide oxygen sensor; The three-lead oxygen sensor is a heated zirconia type oxygen sensor, and in principle, the oxygen sensor with three lead methods cannot be replaced. >>>More
The most common failure of an oxygen sensor is failure, and there are two main reasons for this: >>>More
When it comes to automotive oxygen sensors, we usually know that these two things are locked in the exhaust pipe and are used to monitor the engine combustion exhaust gases. In other words, by detecting the combustion data of the engine and giving the computer a response, it is possible to determine whether the computer needs to be modified. The failure of the car oxygen sensor is solved by itself, with a tutorial - Woodpecker Master. >>>More
Summary. If the oxygen sensor is always broken, it is necessary to check whether the engine exhaust emissions exceed the standard or the oil is burned, which will cause the oxygen sensor to be damaged. >>>More
As an important component of the closed-loop control of electronically controlled engine fuel injection, in order to meet emission regulations and improve the fuel economy of the vehicle, the front oxygen sensor (before the three-way catalytic converter) is mainly used to detect the oxygen content in the exhaust gas emitted after the combustion of the cylinder. >1 (is the ratio of the actual air-fuel ratio to the theoretical air-fuel ratio), at this time, the feedback voltage of the oxygen sensor is sent to the ECU. According to the calculation result of the mixture being too thin, the ECU increases the injection volume (that is, the injection pressure is constant, and the injection time is extended), and vice versa, the injection volume is reduced. (Note that the engine does not have closed-loop control in some operating conditions, that is, the fuel injection volume is adjusted without reference to the front oxygen sensor, such as full acceleration conditions). The rear oxygen sensor is mainly used to detect the oxygen content after the three-way catalytic converter, which is the main purpose of detecting the working effect of the three-way catalytic converter and detecting whether the emission meets the standard.
