I have had luck with removing neg battery cable and turning on the headlights and replacing the neg battery cable. I didn't know about turning the key to the on position, I guess it all has to do with draining the reserve power that keeps the RAM powered (read access memory) that is why the trip odometer resets to zero when you unhook the battery and the odometer has a ROM chip (read only memory) it basically rewrites the info every 1/10 mile you go to keep track of the mileage for the life of the truck.

I have heard of both ways being done just that the key is proven to drain the power whereas I don't think the headlight method has ever been proven but its assumed. But yeah, either way works. With the key, the proper way to do it is hold it on the start position for 20-30 seconds not just the on position.
I have a bad 02 sensor thats throwing CEL, I'm going outside right now to see if it throws that code at me. (since I already know the code and the issue). Thats a cool trick.
