Hello,
I have an INNOVA scanner with live data scan. and I am wondering where I can go find how to interpret the codes while looking at my scanner.

I know some of the things, but I don't know many of the other ones.

Is there a site where I can see what they mean??

Thanks
Jo

Hello,
Would a STFT or LTFT throw a code of P0420?

I have changed CAT, O2 Sensor, and now thinking it might be this.
My STFT B1 S2 is giving me an NA.
My mechanic said that should not be like that.

What would throw this code in the fuel system?? Bad injector??

Any help would be great, thanks.
Jo

No takers huh?? I guess no body knows about this.

Just give it some time Joanne, it is Sunday and the gear head guys are probably working on their wheels and having a beer & sandwich right about now...Something I need to do too..
It may be best to list the codes, are we talking body codes or basic trouble codes?
Here is a list OBDII trouble codes from the Tech Info Section.
OBD-II Trouble Shooting - GM Forum - Buick, Cadillac, Chev, Olds, GMC & Pontiac chat
You can always use google and type in for instance "OBD II p0442 trouble" and voila info coming your way!

I merged these 2 post'* together because they are related.
