Can the damage of the water temperature sensor of the Liuji machine cause the ignition to stall whil

When the water temperature sensor fails, the ECU naturally does not get the signal of over-concentrated mixture, and can only provide the thinner mixture of the engine. Especially when the car is cold, it may be difficult to start the start. Even if you get on fire, the engine still lacks power and stability, and it may suddenly stall at idle or while driving.

The water temperature sensor signal is one of the important indicators of engine work, if the sensor is damaged, the engine enters a limp or fails to maintain the engine work and turns off directly.

Lack of engine power due to non-warm-up start.

Many car owners have a common experience, that is, under the harsh winter, after a night of driving, the vehicle is found to be as lacking power as "not enough". In addition, over time, it is easy to cause more carbon deposits in vehicles. In fact, this is caused by driving in winter without warm-up.

In winter, after the engine has been left standing overnight, the residual pressure of the lubricating oil on the friction surface has long disappeared, and the oil film protection has been lost, and the viscosity of the lubricating oil has been greatly increased by low temperature, and the adhesion and fluidity have become poor. At this time, the movement resistance of the starting engine is greatly increased, and more than % of the power at the start is used to overcome the movement resistance.

In addition, if the engine starts immediately without preheating, the engine will have insufficient power output due to the uneven mixing ratio; At low temperatures, the fuel with insufficient atomization cannot be fully combusted, and carbon deposits are easy to form; Some gasoline is not atomized, and will flow directly into the crankcase along the cylinder wall to mix with the oil, reducing the quality of the oil.

Normal engine warm-up can not only exert the normal power of the engine, but also prolong the life of the engine. In fact, the amount of wear on the engine during cold start is about the same as the amount of wear in other operating conditions. Usually, the amount of wear on the engine during cold start, accounts for about half of the total wear.

Preheating at this time can reduce this wear. At low temperatures, the metal will show less elasticity and wear resistance, and only at operating temperatures can the engine achieve normal mating clearance and maintain optimal working condition.

First of all, whether it is damaged and corroded from the outside. Resistance is then measured, but different sensors measure it differently. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

The easiest way is to use a special car tester to detect! [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, measure voltage, resistance, on/off [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The potential measurement value of a single wire, the measurement resistance value of two wires, and the voltage measurement value of more than three wires.

It depends on what sensor you want to measure, the measurement method of each sensor with different functions is not the same, and even some sensors with the same function will have different measurement methods because of different models, please be more detailed.

Each sensor has its own specified data, and it is possible to measure voltage, current, and resistance, depending on what sensor you are measuring.

The computer will show you a fault code, and you'll have to figure out which sensor is faulty based on the fault code, but a little bit more advanced, the computer will show you which sensor is faulty.

Use 5053 to read the fault code, and it can be displayed.

If you can get on the car normally with electricity and oil, check the cylinder pressure and check the working status of the spark plug. The normal cylinder pressure is around 10 kg. If the cylinder pressure is less than 7 kg, it is recommended to adjust the timing belt first, if it has not been changed, only the engine can be overhauled.

Hello! Please describe the specific vehicle failure, so that we can help you analyze, give professional answers, I hope to help you, if you have any questions, please feel free to come to consult, I wish you a good night!

(The oxygen sensor signal is biased and stuck in a dilute place) should be literally interpreted as the mixture is too thin. Even if the oxygen sensor is broken, the mixture is normal or thick, it should catch fire.

I think these are 2 different things....If there is no problem with the pressure plate and clutch plate separating the bearing, fork, and guide bearing, then it can be determined that the sound is caused by the small tile, and the connecting rod screw is loose, causing the connecting rod to sound and the small tile, and then falling off and breaking through the oil pan.

I'll talk about it in general.

1. Auto maintenance is mainly to solve the problems on the customer's car in the first time.

2. It is the usual regular maintenance.

Maintenance and so on 3, 2 and that includes maintenance and repair issues.

It is a designated maintenance place to put.

Said with the film.

1. Automobile maintenance items include, engine chassis, circuit, sheet metal, painting, 2. Check to change, then change the oil, 3. Engine overhaul is to disassemble the engine, not a screw is left, after checking each part, whether there is a bad, replace the new parts and then put them together, the vehicle frame overhaul is to be sheet metal painting,

1.Repairs are mainly to replace parts that have been damaged. Power, circuit, cold paint, tire repair.

2。Check to change, change the oil again, replenish, lubricate, tighten, adjust, etc.

3.To overhaul an engine is to take the engine apart. Cleaning. Fill in the gaps. Change the pads. Change the piston.

1 power, bottom, circuit, cold paint tire repair! 2. Generally beat butter and change gear oil! Check the full-motion screws for first-level maintenance, and replace them once like brake pads!

Cylinder liner pistons! Count as Level 2 maintenance! 3. Overhauling the engine is to replace all the parts at one time! ok

1.Repairs are mainly to replace parts that have been damaged. 2.Everyday.

The first and second level maintenance is mainly to clean, inspect, replenish, lubricate, fasten, adjust, etc., except for the failure of the main assembly, generally do not implement dismantling operations. 3.The signs of automobile engine overhaul and vehicle overhaul are:

Dismantle the engine and vehicle, and replace damaged parts.

What are some tips for car repair?

The common faults of automobile maintenance are: ABS system failure 1, ABS system pressure relief 2, ABS system computer replacement 3, wheel speed sensor adjustment 4, hydraulic control device maintenance 5, ABS system replacement 6, ABS system degassing 7, hydraulic component leakage inspection.

1. ABS system pressure relief.

2. Replacement of ABS system computer.

3. Adjustment of wheel speed sensor.

4. Overhaul of hydraulic control devices.

5. ABS system replacement.

6. Deflation of ABS system.

7. Leakage inspection of hydraulic components.

1. Automobiles.

BAI common faults: the engine cannot start.

Common causes: zhi1The circuit DAO is faulty or the battery is dead. Expert.

Genus 2Ignition coil or spark plug failure. 3.The oil circuit is faulty, the oil pump is damaged, and the oil tank is free of oil.

Solution: If the battery is out of power, you can use the wire or emergency power supply for ignition, and then, it may be a circuit oil circuit failure, it is recommended to send it to the repair shop.

2. Common faults of automobiles: punctures, punctures and other faults.

Solution: The spare tire should be replaced in time, or the tire should be repaired. If it is a flat-proof tire, although you can continue to drive with a flat air, it is still recommended to repair the tire in time.

When a tire bursts, remember not to slam on the brakes, slam the direction, hold the direction, brake slowly, and deal with it calmly. After the car is stopped, change the spare tire or contact the rescue.

3. Common faults of automobiles: brake failure.

Common causes:1Maintenance is not in place 2Inadequate operation leads to thermal decay.

Solution: Maintain the brake system. Always check the consumption level of brake discs, brake pads, etc. Try to avoid applying the brakes for a long time in daily driving, and go downhill in low gear. Avoid overheating the brake pads.

Fourth, the common fault of the car: abnormal noise.

Common causes:1Abnormal body noise. 2.Abnormal engine noise.

Solution: If there is a slight abnormal noise in the body, it is usually caused by the lack of rigidity of the body, which will not affect the driving, but if there is a violent abnormal noise, it is recommended to stop and check. The engine screeches are usually caused by timing belts, fan belts, etc.

It is advisable to check components such as generators, water pumps, power steering pumps, etc. And send it for repair in time.

The first: burn the oil. The phenomenon of burning engine oil is:

1. Touch the exhaust pipe with your hands, find that there is a black and wet sludge accumulation, and smell the organic oil. 2. Blue smoke comes from the exhaust pipe of the car. 3. In the case of no oil leakage, the oil is seriously lacking.

There are two main reasons why cars burn engine oil. One is the common problem of the model, which is difficult to solve.

One is caused by excessive wear and aging of the internal components of the engine as the vehicle ages. This situation can be solved by simply replacing excessively worn and aging parts.

The second: vehicle jitter. There are many reasons for vehicle jitter. It is possible that there is a problem with the chassis, such as loose structures such as front and rear suspension, steering, and transmission.

It may be a problem with the tires, such as a large difference in tire pressure between the four tires; There is a problem with the dynamic balance of the tire, etc.

In addition, problems in any part of the ignition system, air intake system, and fuel system may cause the car to shake.

Solution: First determine that there is a problem with the car, and then repair it symptomatically.

The third: the fault light of the dashboard is on. For example, engine fault lights, tire pressure warning lights, oil warning lights, and so on. Depending on the model, the difference will be large. It is recommended to check the vehicle instruction manual, which will have a clear explanation.

Solution: Stop for inspection, if the situation is more serious, don't continue driving, contact a 4S shop or a professional auto repair shop as soon as possible, and ask for professional help.

Fourth: battery problems. For example, the battery is losing power, the battery life reaches the limit, and so on. There is a problem with the battery, the car can't catch fire, and there is a "squeak" sound when it is fired, and the car dashboard lights up the fault light.

The life of a battery is generally about four years, that is to say, it is necessary to consider replacing the battery in about four years. In addition, when locking the car at night, be sure to turn off the electrical facilities in the car, especially the headlights, if you forget to turn it off, the battery is easy to lose power the next day.

Circuits, engines, gearboxes, chassis parts, electronic control testing, sheet metal, painting, new energy vehicle inspection and maintenance.

There are a lot of car maintenance, there are automobile electromechanical maintenance (engine, chassis, circuit electronic control), sheet metal repair, painting, these are all car maintenance projects, as long as a project is repaired, the salary is very considerable.

Now there are a lot of auto repair schools, it is recommended to go to the school for field investigation and research, compare and see, look at the school's teacher level, teaching equipment, class mode and employment arrangement, so that you can know in your heart, the most important thing to learn technology is to practice more and practice, in order to learn!

Repair includes all aspects of the entire car's spare parts, engines, these.

The professional classification of automobiles is mainly divided into the following categories: 1, automotive EFI 2, electrician, 3, machine repair 4, sheet metal 5, beauty 6, electronics, etc.

Auto repair enterprises will be divided into three categories: automotive circuit, automotive sheet metal, automotive painting, automotive air conditioning, automotive machinery, and the mainstream projects are automotive electromechanical, automotive sheet metal spraying, and automobile beauty.

The automotive education major mainly includes automobile maintenance and automobile maintenance. Like auto circuits, auto repairs belong to the maintenance category; Car beauty sheet metal spray paint belongs to the maintenance category. The division of majors in formal schools is more refined. For example, our school has more than 20 related automotive majors.

Hello, car repair is a generic term for car maintenance and repair. It is to investigate the faulty car through technical means, find out the cause of the failure, and take certain measures to eliminate the fault and restore it to a certain performance and safety standard.

Automobile maintenance includes automobile overhaul and automobile minor repair, automobile overhaul refers to the method of repairing or replacing any part of the automobile (including basic parts), restoring the intact technical condition of the automobile and completely (or nearly completely) restoring the life of the car. Automobile minor repair refers to the operation repair of the car by replacing or repairing individual parts to ensure or restore the working ability of the car.

There are so many things that affect the burning of the economy, can you tell us about the specific symptoms? What sensors did you get in exchange? What are the symptoms at first?

The method steps are as follows: Detection of the sensor supply voltage. Disconnect the ignition switch, unplug the sensor wire connector, connect with the connector 1 and 3 terminals with the positive and negative meter pens of the multimeter respectively, and when the ignition switch is turned on, the voltage should be above. If the voltage is zero, it means that the wiring harness is broken, short-circuited, or the ECU is faulty. When the ignition switch is disconnected, the wires should continue to be checked for open or short circuits.

Detection of wire resistance. Use the resistance of the multimeter to check the resistance value of the 1 terminal of the sensor and the 62 terminal of the ECU, the 2 terminal of the sensor and the 76 terminal of the ECU, the 3 terminal of the sensor and the 67 terminal of the ECU, and the resistance value between the wires should not be greater. If the resistance is too large or infinity, it means that the wiring harness is in poor contact or the wire is broken, and the wiring harness should be repaired or replaced.

Then use the multimeter resistor to continue to check the resistance between the sensor connector terminals 1 and 2 and 3, or check the resistance between the 62 terminals and the 76 and 67 terminals of the ECU, and the measured resistance should be infinity. If the resistance is not infinity, there is a short circuit in the wire and it should be replaced.
