Where is the air flow of 10 mark 408?

10 Dongfeng Peugeot 408 air flow sensor is installed in front of the throttle. The air grille is located above the pipe in the middle of the throttle grille. If the sensor fails, there will be no correct and effective data flow between the engine module side and the engine-related intake air, and the wrong fuel injection signal will be given. In this case, the fuel consumption of the vehicle will be too high or it will not start. You can check the circuit on the side of the air flow meter first to see if it is caused by poor contact or corrosion between the circuit of the air flow meter and the computer board. If there is a fault in the circuit, the circuit must be eliminated first. If this line is a good signal, it all enters the air flow sensor, but the value displayed on this side of the air flow sensor is wrong, then the air flow sensor is damaged. In this case, it is necessary to replace the air flow sensor. It is suggested that it is best to go to a 4S shop or a professional garage for inspection and maintenance to avoid unnecessary damage to the vehicle due to improper operation of technicians when repairing the vehicle in an ordinary garage outside. At that time, the loss outweighs the gain.
