Engine fault light What's wrong with the light but not the fire?

Generally speaking, most of the fault lights of the vehicle are caused by the fuel emission system. Start and stop the vehicle when the fault light is on. After starting and stopping the vehicle three times, observe whether the fault light is still on when the vehicle starts. If they are still on, you need to go to the store to check the fault code in time. Otherwise, it may be an unexpected fault, and there is no need to go to the store for inspection in time.

Therefore, if the oxygen sensor is damaged or the sensor plug is damaged or loose, the mixed gas will be too thin or too thick, causing the fault light to turn on.

Reference: sensor damage, poor contact or signal interruption; poor engine maintenance; poor quality of fuel and oil; insufficient combustion of mixed gas; spark plug failure, ignition coil failure.

The engine fault indicator light continues to flash, but the reasons for not burning are as follows: the engine maintenance light flashes and does not light up because there is a fault code in the engine electronic control system. It is necessary to go to the repair shop to read the fault code of the engine electronic control system with a computer and analyze the fault point specifically. The general public detects It can't be repaired.

What's wrong with the car not catching fire and the engine fault light is on?

1. Reference: sensor damage, poor contact or signal interruption; poor engine maintenance; poor fuel and oil quality; insufficient combustion of mixed gas; spark plug failure, ignition coil failure.

2. Therefore, if the oxygen sensor is damaged or the sensor plug is damaged or loose, the mixed gas will be too thin or too thick, causing the fault light to light up.

3. The quality of gasoline is poor and does not meet the standard. Soon after refueling, the engine fault light on the dashboard of the car turned on. SameIt is because the non-standard gas station is added with inferior gasoline, resulting in insufficient combustion of the oil and gas mixture when the engine is working, and the engine fault light is on. This will not affect driving safety, but it will more or less cause damage to the engine.

4. Identify the cause of the failure. For the diagnosis of such faults that the engine cannot start, the battery should be detected first. It must be clarified that the engine cannot start because the battery is underpowered. Detect the ignition timing.

What should I do if the engine fault light is on and it can't be ignited

1. If your car's engine fault light is on, it is recommended to go to the nearest repair shop to check the cause of the fault and repair it immediately. There are many fault lights and warning lights on the dashboard of the car. When these lights are on, it means that there is a problem with a part of the car.At this time, it is necessary to check them in time.

2. The solution to the problem that the engine fault light is on and it can't catch fire is: check the status of the car engine in time; check the status of the car's sensor, air flow sensor and spark plug parts; check whether the car has exploded; check whether the ignition coil is faulty; timely repair and return to normal use. .

3. Solution: It is recommended to clean the air filter. In addition, the efficiency of the spark plug is reduced, the water temperature is too high; there is a burst in the cylinder; the oil temperature in the engine is too high, which will also affect the engine power.

4. Fault phenomenon: turn on the ignition switch, turn the ignition switch to the starting position, and the engine does not start.

5. If the start-up system is damaged, you need to go to the 4s store to repair it. Engine ignition system failure.In the early ignition system, the ignition coil can be easily removed, and then an electric spark detector can be used to detect whether the electric spark is normal. If the ignition system fails, you can clean up the carbon or replace the spark plugs.

6. Check the status of the storage battery. Most of the cases, the difficulty of starting a car in winter is caused by the power loss of the battery or the expiration of the battery. When the battery is low, the rotation speed of the car is weak when starting, and only the clicking sound is heard. When the fire is turned on again, the clicking sound will gradually become a clicking sound. Do not ignite continuously to avoid running out of battery power.
