Yes, that is what I was thinking / describing too. But I'm still afraid to be the guinea pig until I find a bit more assurances from others that have more or first hand experience.

There would be different fault codes in that case compared to what you get when you unplug power from the entire unit lol
I'm not sure you understand the VVT system. The motor is just actuating the eccentric shaft per the ECU instructions, with the ESS sensing the position it's in. They are physically and functionally different parts, and they are part of the VVT system.

Back to my question - which way is it ok to try and disable the VVT system, which right now is my #1 suspect in driveability issues in hot conditions ?

Initially it sounded like it would be disconnecting the ESS, then some suggested disconnecting the VVT motor (both are fully functional on the car, no codes). And if any them would do it, what are the consequences ? I'm afraid of doing any damage or other long-term problems to the car/engine. Deleting error codes is not a problem, have INPA.

Somebody has to know and not just speculate like I and others seem to be doing here... (which - don't get me wrong - I do appreciate )
