What is the reason for the engine fault light of Guangzhou Honda Accord?

The Accord's engine failure light may be due to poor engine combustion.

In order to ensure that the engine is in good working condition and normal working life, an oxygen sensor is designed and installed on the engine to monitor the combustion state of the engine. Once the engine is in a bad combustion state, it will cause fuel waste and excessive engine wear.

Common engine faults:

1. Engine abnormal noise: Engine abnormal noise can be divided into cold car abnormal noise and hot car abnormal noise. The abnormal noise of cold car is mainly caused by the oil flowing back to the oil pan after continuous parking. During cold start, the oil pump can't establish oil pressure at the first time to form an oil film. During cold start, the parts cannot be lubricated, resulting in abnormal noise.

2. Engine carbon deposit: The main reason for carbon deposit is that the engine burns incompletely at work. When variables are added to fuel and engine oil, colloidal substances produced during combustion will form carbon deposits over time. The power performance of vehicle engine crankshaft and idle engine crankshaft decreases, and the fuel consumption increases, which can be alleviated by users by removing carbon deposits.

3. Throttle is often dirty: The essence of dirty carbon throttle is that when the engine enters and exits the working stroke, the airflow moves alternately. Air will be sucked in when the air inlet enters, and the gas generated when the valves overlap will return to the air inlet. If carbon deposits form in the pipeline, users can clean the throttle valve.
