What is the fault when the EPC light comes on in S gear?

[SanCourtney]

EPC light on indicates a fault in the engine electronic control system. Focus on checking the wiring, electronic throttle, and engine computer. It is recommended to go to a repair station for inspection. Generally, there are two possibilities when the EPC light comes on. One is a dirty throttle, which should be cleaned. The other situation is that the brake light is not working, and the brake switch and wiring need to be checked. Here is some extended information: 1. Yellow warning light: The yellow warning light on a car indicates a warning, suggesting that some systems in the car may have parameters exceeding the standard, which are different from the initially set parameters. The yellow light indicates that this is not a very urgent fault. When the car's driving computer detects an abnormal signal and the yellow warning light comes on, the system will handle it on its own. 2. Red warning light: The red warning light will affect driving safety. If the red warning light comes on, it will directly affect the car's core components or driving safety. At this time, you should pay attention to stopping the car, then check the car's fault, and solve the fault before driving on the road.
