Hey guys, today the check wrench signal light came on in my car. Everything seems fine after a start up and I also cleared the code. It was the only one. I read everything I could about this code but I don't get what could trigger it.
I've found that there is a recall for the warped air box leaking air. My lower part of the box is not warped but the top one yes. My air filter seal is also ripped so I'll change it and see.
I guess that some snow went directly on the MAF and then a PCM miss calculation occured.
Do you have any ideas?
