StartWhy does the fault light of the machine turn on and off

1. [Pacific Automobile Network] The reason is that the sensor misreported the fault code. With the use of the vehicle, the driving computer found that there was no real fault. After several ignitions and self-examinations, the fault light automatically turned off.

2. The specific analysis is as follows; sensor problems; sensing volume, intake temperature, oxygen sensor, etc. mentioned here. When these sensors are damaged, poor contact or signal interruption, the ECU of the car cannot accurately obtain the engine data, which will cause the engine failure light to turn on.

3. Cause of failure: This situation may be at the start of winter or when the temperature is relatively low, because the internal temperature of the engine is also relatively low.

4. The engine fault light sometimes turns on and turns off for the following reasons: oil quality problems.The fault light of the engine sometimes turns on and off, which may be related to the non-standard quality of the oil used.

5. First of all, the car can't start. This may be caused by the failure of the fuel pump or ignition parts. Call for help directly. Second, the fault light is on, but there is no abnormality in the steering. It may be a sensor failure. In this case, you can continue to drive for the time being, but it is better to drive slowly at a lower average speed and repair it after reaching your destination.

Mazda 6 engine fault light is sometimes on and sometimes not on (Mazda 6 Engine fault light appears)

1. The main reasons why the engine fault light of Mazda 6 are on are: most of these cases are caused by missing cylinders, the ignition coil is damaged or the spark plug gap is large. It is recommended that you go to the 4s store to use a special computer detector to detect the fault and carry out targeted maintenance according to the fault.

2. The reasons why the Mazda 6 engine fault light is on are: most likely to be caused by a lack of cylinder, the ignition coil is broken or the spark plug gap is large. It is recommended to go to the 4s store to detect the fault with a special computer detector for corresponding repair.

3. Mazda 6 (Check the transaction price | Detailed explanation of the model) There are many reasons why the engine fault light is on. Generally, the reasons why the engine fault light is on are: it may be that the engine vacuum hose is damaged, aging, and there is air leakage.

4. The causes of the engine fault light are: poor combustion of mixed gas, sensor problems, maintenance problems, and oil quality problems. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (resurrected engines), external combustion engines (String engines, steam engines, etc.), jet engines, electric motors, etc.

5. If the engine fault light is on, it may be caused by a problem with the circuit or the sensor. After encountering this situation, you should go to the local 4s store to find a professional technician to use a professional diagnostic computer to read the fault code.Ma Liu is Mazda 6, which is a medium-sized sports car under Mazda.

6. When the Mazda 6 engine fault light is always on, use WDS to diagnose the fault first. The engine system has a fault code P0753, indicating the fault of the gearshift solenoid valve A (electrical fault). Refer to the maintenance manual. When the voltage of the control terminal 1A between the power system control module and the gearshift solenoid valve A is 0V or +B, the code will be reported.

Engine fault light is sometimes on and sometimes not on

Engine fault light is sometimes on, sometimes not on, indicating that there is something wrong with the engine. Sometimes it's bright, sometimes it's not bright, indicating that the problem is not very serious. When the engine fault light does not affect normal driving, the engine fault light goes out and turns on during the fault.

The engine fault light is sometimes on and sometimes it is not on, indicating that the engine is faulty. When it does not interfere with all normal operation, the engine fault light will be turned off, and when there is a fault, the yellow or green light will be on.

Cause of failure: This situation may occur when starting in winter or when the temperature is relatively low, because the internal temperature of the engine is also relatively low.

The engine fault light is sometimes on and sometimes not, indicating that there is something wrong with the engine. Sometimes it's bright and sometimes it's not bright, indicating that the problem is not very serious. When it does not affect normal driving, the engine fault light will go out, and when there is a fault, it will turn on.
