Actually, no, it is a Toyota Truck. But the OBDII information on this site,
http://www.wattora.com/Mods/OBDII/, says that all vehicles use mostly the
same codes. So, if a vehicle makes a P0440, then all vehicles that make the
code have the same problem and all vehicles that have the problem make the
same code. There are some codes that are manufacturer specific, and I am
ignoring these for the moment.

Having said that, I notice several descrepancies in the link I posted and
the one you posted so I must not fully understand all that I think I know.

All I was saying is that in the link you posted, there is a code, P0439 that
says two different things. The second thing it says is really code P0440. I
am sure this is nothing more than a typo on the part of whomever created the
list, and the proofreaders were simply dizzy from all of the data that looks
nearly identical from one line to the next.

And, it turns out my daughter's gas cap tossed up a 440, 441, and 446 if
anybody cares.
