Hello and thank you for using Just Answer. My name isSteve and I will be assisting you with your question. The fault you have indicates that the crankcase pressure sensor is less than desired. This is normally caused by a leaking crankcase breather hose which is the hose that comes off the drivers side of the valve cover and goes down to the breather canister . If there is no problem there I would make sure the oil fill cap is on and tight. There has been software updates on this fault as well placed out over the years. If all that checks out then the pressure should be monitored with a scanner to see if you have an issue with the sensor or the centrifuge. Please let me know if you have any follow up questions on this. Thank you

Is there a way to turn the front lane sensor. It press the brake down if any vehicle changes lanes in front of me.
Technician: Mike Mcmillan, Shop Foreman/Triage Tech replied 3 years ago

I am sorry but we are unable to answer questions outside of the original one posted. I will say that the lane departure system sensitivity can be adjusted with a service tool. It is a safety add on so there is limited allowance of change for it
