What's wrong with Jianghuai Shuailing Guowu epc lamp?

The lighting of Jianghuai Shuailing Guowu EPC is a possible failure of the electronic throttle system, which may affect the normal use of vehicles. EPC is called engine electronic throttle system, commonly known as electronic throttle system. The system is mainly composed of engine adjusting unit, engine wiring harness, throttle, accelerator pedal, brake switch and manual transmission clutch switch. The causes and solutions of EPC lamp are as follows: 1. There is too much carbon deposit in the throttle valve, and the opening is problematic, so a new throttle valve needs to be replaced; 2. The throttle valve works abnormally due to engine fire and lack of cylinder, so it is necessary to check whether the engine spark plug, ignition coil and fuel injector are faulty. If there is a fault problem, new accessories need to be replaced; 3. Air leaks behind the throttle valve, and the inspection data of the intake pressure sensor is abnormal. These conditions will basically light the EPC lamp. The throttle or intake pressure sensor needs to be replaced with a new one.
