What does it mean that the Volkswagen Bora speed sensor is faulty

The collision sensor plug is not plugged in properly or is broken. Just replace that sensor. Then use the computer to reset the matching.

1. The sensor is a detection device, which can feel the measured information, and can transform the felt information into an electrical signal or other required form of information output according to a certain law, so as to meet the requirements of information transmission, processing, storage, display, recording and control.

2. The characteristics of the sensor include: miniaturization, digitization, intelligence, multi-functionalization, systematization, and networking. It is the first link to realize automatic detection and automatic control.

The existence and development of sensors allow objects to have senses such as touch, taste, and smell, allowing objects to slowly become alive. It is usually divided into ten categories: thermal elements, photosensitive elements, gas-sensitive elements, force-sensitive elements, magnetic sensitive elements, moisture-sensitive elements, acoustic components, radiation-sensitive elements, color-sensitive elements and taste-sensitive elements according to their basic sensing functions.

The definition of "computer showing transmission sensor failure" in a car is rather general. It is recommended to use software to better detect the gearbox system, look at the fault code and the parameters of the gearbox sensor and solenoid valve, and then analyze the cause of the failure.

Check the line first if it's okay. Then go to 4S to check the computer fault code, it is possible that the sensor is broken, or it may be that the line is loose.

Automatic transmissions are generally line faults.

It means that the speedometer is inaccurate

Usually installed in the drive axle housing or transmission housing, the vehicle speed sensor signal line is usually installed in the shielded jacket, which is to eliminate the electromagnetic and radio frequency interference generated by the high-voltage electric fire wire and the vehicle** or other electronic equipment, and is used to ensure that the electronic communication is not interrupted, and to prevent the deterioration of driving performance or other problems.

The vehicle speed sensor detects the speed of the electronically controlled car, and the control computer uses this input signal to control engine idling, torque locking of the automatic transmission, shifting of the automatic transmission, opening and closing of the engine cooling fan, cruise control and other functions.

The old Volkswagen Bora speed sensor, located on the top of the gearbox, is a black three-wire sensor that senses the differential rotation speed of the transmission, which is the rotational speed of the propeller shaftThe specific steps found are as follows:

1. Open the door on this side of the cab.

2. Pull the hood switch on the left side of the driver's leg.

3. Lift the hood of the engine upwards.

Fourth, look down from the top of the engine.

Fifth, this is the sensor in the picture.

Precautions for operation:

1. If you want to remove this sensor, you need to ensure that it is clean, the following is the inside of the gearbox, if you drop a foreign object, you need to disassemble the gearbox to take it out.

2. Do not start the engine after dismantling.

One is under the gearbox chicken feet, and the sensor is wired, and this one will not jump if it is broken.

Now the car is electronically controlled engine, there are a lot of sensors to detect the working condition of the engine, and then the signal is fed back to the computer, after the computer analysis and comparison, and then to control the fuel injection ignition and air intake, if the engine sensor detection is problematic, the computer will report the fault code, to remind the owner, the engine needs to be tested and repaired, so we have to find out the cause of this failure, there are often the following reasons, for reference only: 1. The sensor is damaged, the contact is poor or the signal is interrupted; 2. Poor engine maintenance; 3. The quality of fuel and oil is not good; 4. The combustion of the mixture is insufficient; 5. Spark plug failure, ignition coil failure; 6. The fuel pump is faulty and the oil circuit is blocked; 7. The air conditioner filter is blocked.

The specific situation is analyzed as follows; 1. Sensor problems; The sensors mentioned here include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car can not accurately obtain the engine data, at this time it will cause the engine fault light to turn on. 2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that the vehicle has a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light to care about your car 3, oil quality problems; The oil quality here includes fuel and engine oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, which type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame.

Poor combustion of the mixture; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture is caused by the problem of engine carbon deposition or knocking, and these will eventually be detected by the engine's oxygen sensor and reported to the ECU, which will naturally turn on the fault light to warn of the intake air intake problem; When the engine burns, it needs to take intake, the air filter element is very important in this process, if the air filter element of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly, and it will be blocked for a long time, and if it is serious, it will cause the engine failure light to turn on. pressurization issues; Intake booster lines and turbochargers can also cause engine failure lights to illuminate.

The most common of these is turbocharger damage, while the vehicle can also experience symptoms such as oil leakage, high oil consumption, loss of power, metal noise, and blue or black smoke from the exhaust pipe. 7. Exhaust problems; Rear oxygen sensor, three-way catalytic converter, exhaust camshaft and bearing. The most common of these is a failure of the three-way catalytic converter that causes the engine failure light to illuminate.

The use of leaded gasoline, the use of leaded or silicone lubricant additives, the bump of the three-way catalytic converter, and the failure of the engine oil supply system are some of the factors that can easily cause the failure of the three-way catalytic converter.

Summary. AbstractThis problem is caused by the damage of the sensor itself, the failure of the valve body and the internal problems of the computer, you can first use an oscilloscope to check the output waveform of the sensor, the normal is a square wave. With the throttle pressed, the engine speed increases, the frequency of the waveform is also changing, and the sensor is damaged when there is an abnormality.

After testing, these places are good, just replace the transmission computer directly, and the new or dismantled transmission computer needs to be reprogrammed, otherwise it cannot be used normally. After replacing the transmission computer, you need to learn the characteristics of the solenoid valve after programming, otherwise it will cause gear shock and driving frustration.

Hello! Master, take a look at this fault.

Abstract If this problem is that the sensor car ballast itself is damaged, the valve body is faulty and the internal problems of the computer cause this blue, you can use the oscilloscope to check the sensor output waveform first, and the normal is a square wave. With the throttle pressed, the engine speed increases, the frequency of the waveform is also changing, and the sensor is damaged when there is an abnormality. After testing, these places are good, just replace the transmission computer directly, and the new or dismantled transmission computer needs to be reprogrammed, otherwise it cannot be used normally.

After replacing the transmission computer, you need to learn the characteristics of the solenoid valve after programming, otherwise it will cause gear shock and driving frustration.

This situation is caused by the sensor itself is broken, and the sensor itself is short-circuited or open-circuited.

Let's try to change the input wheel speed sensor first.

Yes. Do you want to change the output together?

Not yet. He just changed the transmission oil a few days ago, and this problem came out, does it have anything to do with the transmission oil, and it has nothing to do with the transmission oil.

Summary. Dear, <>

Hello: Volkswagen Bora sensor failures can generally only be replaced, not repaired. The vehicle sensor is the input device of the automobile computer system, which converts the information of various working conditions in the operation of the car, such as vehicle speed, temperature of various media, engine operating conditions, etc., into electrical signals and transmits them to the computer, so that the engine is in the best working condition.

What should I do if Volkswagen Bora has repeatedly reported the failure of the left front wheel sensor.

Dear, hello: the left front wheel sensor is 100 yuan a Kai search stool. There is only one leak on the left front wheel, which sensor is the ABS sensor.

Its function is to sense the wheel speed, and after the damage, the instrument will light up the ABS fault light and side slip light. Sensorlic damage must be replaced. After replacement, you can clear the fault code and you can use it normally.

Is it still the same after changing a few sensors, and the left front wheel sensor will be reported after a week.

Dear, <>

I'm happy to answer for you: Is it a freshly changed tire?

No, dear, I'm honored to answer for you: this sensor is a fake token of damage and external force tearing. Dirty sensor heads and contamination by magnetic rot positive substances may lead to slip fluid to cause wheel speed sensors.

It's all cleaned up of material pollution, and it's all the same.

Dear, hello: A similar case of this chain of rapid contact with the other party is that the gasket in the half shaft and bearing in the left front clear wheel is damaged, and after replacing the gasket, it will be normal. You can go to the shop to overhaul it and answer the sedan car to check the problem of the left front wheel.
