If so, what did it turn out to be. I can read the code dictionary as well as anybody, so don't just tell me what it might-could-possibly be. Has anybody had actual experience with this code? Just replaced ECT sensor because it showed open. Reset code history, same code instantly appears. Good continuity from sensor to ECU.

 

I never had this issue but my friend did and he just changed the sensor. Since then he has never had that issue pop up again.

I wish I could give you a little more on the subject but that is all I know apart from what we already know about the code.
