Help with OBD research project

Hello All

I am a contract research librarian (with a 04 Frontier, supercharged) looking into the number of "hits" OBDII diagnostics show as "faulty or loose gas cap" Is this information collected anywhere? Does anyone know where I should start looking? Is this a standard code on all OBDII processors. Would I be lucky enough to find an OBDII expert on this forum?

Thanks in advance

yes, the gas cap code is a 'generic' (in that the EPA requires the code on all cars sold in the US regardless of model) but Im not sure if there is any repository where the individual codes are kept?

Domestic manus DO keep records of what services are performed on each car, sorted by VIN then by owner, but I am fairly certain they do not record the diagnostic info (although each dealer would have that on the paper/computer record as long as it exists)

Because it was an EPA issue, I was thinking there had to be some reporting, perhaps at state level or why would there even be such a code. What is the code anyway, if you know.
