At idle, it wont code. Once you reset it, the ecm will allow finction to turbo, but for the ecm to know that, you need to drive in a particular manner. Meaning, You need to do a drive cycle. Once it codes, dont erase plz, I want the freeze frame at time of event plz. That way we can see at what demand engine was at.If I clear the P0299 code then shut off the engine, then restart it, will the code set at idle or do I have to drive it...in other words engage the turbo boost...for the code to reset?
