Cars honk for several reasons.

Too much carbon deposit in the engine of Pacific Auto Network is a very important reason, mainly due to the use of inappropriate oil products. It is suggested to add a certain amount of detergent when refueling, and it is best to drive at high speed after cleaning, which is beneficial to increase the exhaust volume and let the strong airflow bring out larger carbon particles.

Check the oxygen sensor: As the internal control unit of the automobile, the oxygen sensor mainly monitors the air-fuel ratio of the engine. Once damaged, the air-fuel ratio of the engine will be unbalanced, and the fuel consumption will definitely increase suddenly. The oxygen sensor is damaged, and the exhaust pipe will emit dark exhaust gas when the vehicle is driving, so the oxygen sensor should be replaced.

Replace the three filters regularly: the oil filter, air filter and gasoline filter must be replaced regularly during the use of the vehicle. If it is not replaced for a long time, it will become dirty and greasy, which will affect the use and send an error message to the engine control unit, resulting in insufficient fuel combustion and increased carbon deposition in the engine.
