Hello. The trouble codes you have listed do not appear to be in the typical format for automotive trouble codes. Trouble codes are listed with a letter P followed by four digits. If your EPC light is on that indicates that the computer has detected an issue with the vehicle’s electronic throttle control system. This is likely the reason why your vehicle is in reduced power mode. Common causes for this light are a faulty throttle body or an issue with the throttle body circuit. If you are unsure of the trouble codes, I would recommend having a professional technician, such as one from YourMechanic, visit your location to diagnose the issue.
