reading codes with a scan tool
when using a scan tool to read codes, should you be only concerned with the codes the actively pop up or any code that the scan tool reveals. i have a predator and when i look for trouble codes, i get one for the fuel level sending unit. not a big deal. but then there is an option to check for other things (can't remember what it is called), this is where i get nine codes. some are absolute pressure, maf something, tranny control slipping, and catalyst system below threshold, among others. i know i have some codes turned off, like rear 02's, and egr, but are these things that my tuner has turned off for me that i am looking at?
if more info is needed please feel free to ask.

no they aren't persistent (they never pop up). just something i found while playing with the predator. only recent codes where the fuel level sensor, no cats, and the misfire. but the later two have since disappeared.
