What is the solution when the vehicle displays EPC and won't start?

[MacCollin]

If the car shows EPC and won't start, it can usually be resolved by restarting the vehicle. If the EPC light remains on after restarting: It may indicate a fault in the car's intake system, which requires inspection. Check the throttle body to ensure it's functioning properly. Also, verify the cylinder pressure is normal, as abnormal cylinder pressure or poor operating conditions can trigger the EPC warning light. In some cases, the EPC light may be triggered by a false alarm, which can often be resolved by restarting the car. About EPC: EPC stands for Electronic-Power-Control, known in Chinese as the engine electronic stability system or electronic throttle. When the car won't start and the EPC light is on, it usually indicates a fault in this system. The EPC indicator is commonly seen in Volkswagen vehicles. Typically, when the ignition is turned on, the vehicle performs a self-check, during which the EPC light will illuminate but should turn off shortly after. If the light remains on after the vehicle starts, it indicates a mechanical or electronic system fault that needs immediate attention to avoid affecting normal driving.
