What is the reason why the Buick Enlang engine fault light is on (Buick Enlang engine light is on, what is the fault...

exhaust problem: Exhaust failure will also cause the engine fault light to light up. The faults of post-oxygen sensors, ternary catalysts, exhaust camshafts and shaft tiles are all causes of exhaust problems, among which ternary catalysts are the most common.

The reason why the Buick engine fault light is on is as follows: the exhaust emissions do not meet the standard. For example, poor fuel, ternary catalyst failure, excessive carbon accumulation in the intake pipe, blockage of fuel injector, oxygen sensor failure, occasional engine lack of fire, etc. will all cause the engine fault indicator light to light up.

The reasons for the Buick Enlang engine fault light are as follows: exhaust emissions do not meet the standard: such as poor fuel, ternary catalyst failure, excessive carbon accumulation in the intake pipe, fuel injector blockage, oxygen sensor failure, occasional engine shutdown, etc.

The reasons for the failure light of the Buick Enlang engine are as follows: First, this phenomenon caused by problems with the sensors related to the vehicle engine system needs to be decoded with a computer to focus on checking the intake pressure sensor and the intake and exhaust camshaft adjustment solenoid valve.

When the ignition switch is turned on, it is normal for the engine fault indicator light to light up. When the engine is running, if the indicator light is on, it indicates that the emission control system is faulty. It may exceed the allowable emission limit. Indicates a fault that may cause damage to the catalytic converter. Please lower the pressure on the accelerator pedal until the indicator light stops flashing.

After the Buick Enlang engine fault light is on, you must stop the car immediately for inspection. After determining the cause, repair it. There are many reasons why the engine fault light of Buick Enan is on.If the added fuel is of poor quality or oil pollution, it will also cause the engine fault light to turn on during driving.

What to do when the fault light of Buick Yinglang engine is on

1. After the Fault light of the Buick Enlang engine is on, it must be stopped immediately for inspection. After determining the cause, it must be repaired.

2. You need to go to the repair shop to check the fault code in time. Check whether it is an engine problem or a sensor failure. When the engine fault light is on, the vehicle should be started and turned off. After starting and turning off the car three times, start the vehicle again and observe whether the fault light is still on.

3. After the Buick Enlang engine fault light is on, it must be stopped for inspection immediately. After determining the cause, it must be repaired. There are many reasons why the engine fault light of Buick Enan is on. If the added fuel is of poor quality or oil pollution, it will also cause the engine fault light to turn on during driving.

4. The ternary catalyst needs to be replaced. The solution of Buick Hideo engine fault light is as follows: exhaust emissions do not meet the standard: poor fuel, ternary catalytic converter failure, excessive carbon accumulation in the intake pipe, fuel injector blockage, oxygen sensor failure, engine occasional fire, etc.

5. Ways to eliminate faulty lights include replacing spark plugs, cleaning oil lines, cleaning up accumulated carbon, etc. In fact, it is difficult for car owners to find the source of the fault light, while 4s stores and repair shops can use fault diagnostic instruments to identify the general direction that causes the fault light to light up.

6. It seems that this situation is mainly due to the failure of the electronic control system in the engine. It is enough to go to the repair shop every day to read the fault code with the decoder and then repair it.

What should I do if the Buick Enlan engine fault light is on

It is necessary to check whether the exhaust gas of the vehicle meets the standard, and the ternary catalyst needs to be replaced.The solution to the buick engine fault light includes the following three: the exhaust gas emission does not meet the standard.

You need to go to the repair shop to check the fault code in time. Check whether it is an engine problem or a sensor failure. When the engine fault light is on, the vehicle should be started and turned off. After starting and turning off the car three times, start the vehicle again and observe whether the fault light is still on.

After the Buick Enlang engine fault light is on, you must stop the car immediately for inspection. After determining the cause, repair it.

After the Buick Enlang engine fault light is on, you must stop the car immediately for inspection. After determining the cause, repair it. There are many reasons why the engine fault light of Buick Enan is on. If the added fuel is of poor quality or oil pollution, it will also cause the engine fault light to turn on during driving.

If the engine oil pressure light is on: engine lubrication may be interrupted. This may cause engine damage and/or drive wheel lock. The following operations should be performed: step on the clutch pedal (manual transmission). Select the idle gear and set the shift lever to N gear. Leave the traffic as soon as possible without interfering with other vehicles.

After this happens, the car can't drive. It needs to be turned off and started again after ten minutes. If the fault problem persists, you need to contact the repair shop for repair and use the detection computer to read the specific fault problem code to repair the car.
