2.7L, 79k miles
Trouble Code: P0441
I tightened the gas cap and cleared the codes. The MIL went out. I now
have no codes in the display of my scan tool, yet, but I do have indicators
on my scanner for:
EV = Evaporative System Monitor
O = Oxygen Sensor Monitor
I suspect that the indicators on my scan tool are telling me that the
systems indicating errors need to go through a full cycle of testing before
they will go out.
1.) Could all this be caused by a loose gas cap?
2.) Is my assumption on the test cycle completion correct?
