These codes indicate there is likely a wiring problem or the ECM (Engine Control Module) needs to be replaced. At this point you would want to bring your vehicle to the dealership so they can erase the codes and reflash the computer then check again what codes come back and go from there. If the ECM is the problem you can get a used one from www.car-parts.com sort by price and have them ship it to you. Let me know if there is anything else I can do to help. Thanks
