I have a 2016 F-250 Lariat with the 6.2L. Just under 90,000 miles. I've had these 2 codes come back a few times now. The last time I had both these codes I replaced the PCM and it seemed to last about a month or more and then both the codes came back today. I had the coils checked and the plugs as well as the wires. It was tuned but since this all started I put it back to stock thinking maybe the tune was causing the codes. Anyone out there experience these codes together? Any ideas or advice would be greatly appreciated. Thanks!
