What is the fault of epc light on freight car and how to solve it?

The reason why the epc light on the freight car is on is: 1, and the accelerator is seriously carbon-deposited: the most critical reason why the epc light is on is that the accelerator is seriously carbon-deposited. When the carbon deposit on the accelerator is serious, there are still problems such as weak acceleration, high fuel consumption and difficult start-up of the truck. 2, the engine temperature is too high: the car engine overload time is too long, which will lead to multiple fault lights. In this case, the car should be turned off and cooled naturally. If the engine still fails after cooling, it will be repaired by a repair shop or 4s shop. 3. Air intake system failure: If the air intake system of the truck fails, especially the ventilation system of the crankcase leaks, the epc light of the car will also light up. Handling method after the automobile epc light is on: 1. Clean the engine throttle immediately. 2. Check the automobile air intake system and clean the ventilation pipes. 3. rewrite ecu data.
