Hello, Time is running too fast :) 9 years after this post, I still didn't found the cause of safety boost. 2009 - All is OK but Safety Boost During this time I was very happy to found and fix a intake leak, but unfortunately it didn't fixed the problem. During this pull I forgot to replug the main knock sensor, but I have another one bolted on cylinder head that still detect knock.
So the car is still running with sensor bypass. I read again this old post, and guys suggested VTC or O2 So I checked them lately. VTC: Youtube VTC active test VTC are clicking individually when tested with engine OFF
O2 values look not so bad, even if a sensor looks more sensitive. Any suggest ? O2 :
