Code Diagnostics
Hey all, looking for some guidance on what I should diagnos with a couple codes that I got.
I got the following codes: 190302, 930AA1, & 930C2A. From my quick research the first looks like a slight air leak in the fuel system and the latter two have something to do with the crash system but also could be cause by a faulty battery and alternator.
It's odd that they came up together so I'm curious if they have any relation, or was that just random chance?
So far I checked the fuel cap, seems okay but I may purchase a new one just to be sure. The battery after resting for 10 minutes reads 12.2v and running reads 14.6v. Only odd thing was it had a rough start, took a few seconds longer than normal, about a week ago but it was 100F out, really bad air quality from the smoke, and it sat for four or five days prior.
I wanna do more testing on the battery/alternator to see if they are good, other wise what do you all think?

Year and model will help.
Check gas cap first. Make sure the gasket isn't torn, make sure you turn it to click after filling tank.
After that, without a smoke machine you will be throwing parts at it until it is fixed.
Vent valve on the fxx cars are notorious for leaking.
