Resetting Service Engine Light
The red one can be reset by the owner.
On DII's there is only one light, "service engine soon" and cannot be reset without a scanner.
The code was P0455. I found it had a loose gas cap so I tighten it. The code hasn't gone away yet thought I might have to reset it. The truck has 59,270 miles thought it also might have been the 60000 mile service warning

A 455 code will not go away on its own, no code will except for a soft code like one thrown when doing an induction cleaning.
A scanner is the only way to clear it and a 455 is a gross evap leak normally not caused by a gas cap being loose.
You will need to have some track down your vapor leak.
