The fault light of the golden passenger car is always on, and the fault light of the golden passenge

Dirty throttles affect oil burning, and dirty nozzles. Remove after cleaning the throttle and changing the nozzle. However, the background speed of the cleaning throttle is very unstable, and it will be good after a while. Hope.

The fault light is always on, it is the sensor on your engine that is broken, and the fuel consumption is generally high at idle speed. The one out there could burn out your computer.

Reasons for the engine failure light: 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. Blockage of air conditioner filter 1. Sensor problem; 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 car maintenance, coupled with bad driving habits, 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 generally recommends the owner to use which grade of the fuel to slow the stupidity, what type of engine oil, if the owner does not add as required, the long-term start will cause wear and tear of the engine, 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 failure light of the starter.

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 silicon lubricating additives, the three-way catalytic being bumped, and the failure of the engine fuel supply system are some of the factors that can easily cause the failure of the three-way catalytic converter. anti-theft system; If the car's electronic anti-theft system fails, the Chinese market will be highly valued and the Chinese market will be regarded as its global.

Or the anti-theft controller does not match the engine electronic controller, and the anti-theft system will also cause the engine to not work properly, and the engine fault light will be lit at the same time.

Hello, it's a pleasure to answer your <>

The reason why the engine failure light of the golden passenger car is weak and the car is weak: Wang Yinshu 1Oxygen sensor malfunction.

2.Air leakage in the intake pipe causes the mixture to be too thin. 3.

The fuel pressure is low, and the injectors and fuel filters are clogged. 4.The signal of the pressure sensor and throttle position sensor is abnormal.

5.The abnormal signal of the sensor leads to the inaccuracy of the ignition bending fire and the ignition is too late. The above is the golden passenger car, the engine failure light is on, and the car is powerless.

What is the reason why the wf fault light of King Long bus is on?

When the automobile engine is not working properly, and the self-diagnosis system does not have a fault code output, it is especially necessary to rely on the operator's inspection and judgment to determine the nature of the fault and the location of the fault. The author now summarizes the common faults of automobile engines as follows: The engine cannot be started (1) Fault phenomenon:

Turn on the ignition switch, turn the ignition switch to the starting position, and the engine of the hair tank cannot be started. (2) Possible causes of the failure to disturb the disturbance: a

The engine cannot rotate or rotates too slowly due to the failure of the starting system: the battery is not stored enough, the electrode pile clamp is loose or the electrode pile is seriously oxidized; The main fuse of the circuit is broken; Ignition switch failure; starter failure; The starting line is broken or the line connector is in poor contact. b.

Ignition system failure: The ignition coil works poorly, resulting in weak or no high-voltage sparks in the high-pressure mill; ignition failure; The ignition time is incorrect. c.

Fuel injection system failure: There is no fuel in the tank; The fuel pump is not working or the pump oil pressure is too low; Fuel line leakage and deformation; The disconnect relay is disconnected; The fuel pressure regulator is not working well; The fuel filter is too dirty.

The malfunction light of the Golden Dragon Energy bus shows smoke, indicating that the bulb is broken somewhere in the car.

Lights need to be detected immediately throughout the vehicle, and most can be turned off after replacement. The lights often encountered in the car are: turn signals, brake lights, license plate lights, wide lights, front and rear fog lights, reversing lights, high beam headlights, low beam headlights, etc.

All the lights have basically been detected, and there is no problem, but the fault lights are still on, and there are the following possibilities:

1. There is a virtual connection in the line, which affects the resistance value of the light line, and the instrument computer mistakenly thinks that the bulb is abnormal.

2. Poor line contact.

3. The filament of the bulb seems to be broken.

This indicator is used to show the condition of the vehicle's brake disc wear. Generally, the indicator light is off, and when the brake disc is faulty or worn over, the light is lit and extinguished after repair.
