Just replaced engine harness on this truck, had multiple codes and bad wires. Only codes left are e 01-5 and e 06-1. Have had the o2 sensor code on same model truck but it would still run and drive. The throttle motor code is harder to diagnose whether it is the etc or the ecm. Code only comes up after starting and immediatly goes into limp mode. No throttle response at all. Any help or directions would be appreciated.
