I'm thinking about goin out if state to buy an ep3 the guy said it doesn't pass smog cause it needs an 02 sensor and a MAF sensor I been looking around some people say there is a MAF sensor some say it doesn't ?? So does it or does it not ?

 

There is no maf. Only map.

 

he is correct. We only have a MAP sensor. Some of those CEL codes are very universal and poorly written to just give you ideas and help. So O2 / MAF is just a common wording.
