Indeed it is, Mike.
And your list of possibilities are indeed make/model/year-independent.
Always nice to know what you''re diagnosing, though.
For example:
While googling the code, I came across dirty "MAF sensor" as a possible culprit and since L cars use MAF sensors and S series use MAP sensors, I thought it''d be nice to know whether we''re talking L or S series here.....lest I suggest to an S car owner to clean his (non existent) MAF sensor....
