What is the reason for the EP8 light of modern cars?

There is something wrong with the engine and electronic system, or there is a serious carbon deposit on the throttle.

If there is something wrong with the engine and electronic system, the light will always be on or flashing after ignition or during driving, indicating that the management system has detected the fault of the engine or electronic system.

When the engine and electronic system fail, it means that the management system has detected that the engine or electronic system of the vehicle has failed. Please contact the service station immediately for a solution.

Throttle carbon deposition is serious. The solution to dirty electronic throttle is to go to the maintenance office for cleaning. If the engine stalls due to improper operation, the indicator light will also light up. At this time, you can try to ignite again.
