You have to atleast be on the white line you have crossed it. :)
If the check engine line is flashing then that means there is a real problem and you should have it looked at, But if the light is on and NOT flashing the it is most likely a problem with the emmisions system and most likely an oxygen sensor.
A flashing line in eye is one of the phenomena called a scintillating scotoma (plural scotomata).
just like was said,coolant low or bad switch,or needs air bled from the line
It's called a cursor.
that light indicates that you're vehicle is low on water. the big white sphere container at the top right of you're engine is the water resivoir. if the vehicle is warmed up then make sure the water level is up to the "MAX" line indicated on the resivoir tank.
Usually a big white line, if there is no line- out of the way of opposing traffic.
it will be default or highlight because the clue word was flashing vertical lines that indicates
There are three... white, light green and light green with a black line on it.
is there something in the way if there is move it if there is sensers clear everything out of the line between both of them
it is simple you go in a line from purple then stop at white.
It depends on what computer it is, and what age it is. I would turn it off & leave it for a few days, and if it has not fixed itself take it in to where you got it.
