Your post is confusing ok you didn't pass inspection did you remove the battery cables to clear codes or to do regular work requiring the battery to be disconnected I don't understand what senor won't means but if the battery was disconnected there are midules that must be set and once they do there will be a P1000 code set and your vehicle will be ready for inspection this requires at least 30 or more miles to be driven and if it's your EVAP MODULE THAT'S NOT SETTING IT MUST BE DONE AFTER OVERNIGHT COLD AND STEADY DRIVING ON THE HIGHWAY GO TO AUTOZONE AND GET A READ OUT OR ANOTHER SCAN TOOL THAT SHOWS YOUR SYSTEM MODULES GAS TREATMENT IS GOOD FOR THE SYSTEM BUT YOU WON'T PASS INSPECTION UNTIL THOSE MODULES CLEAR AND YOU GET A P100 SYSTEM READY CODE WHICH YOU WILL SEE ON A GOOD SCAN TOOL ALL MODULE'S WILL BE GREEN OK ANY REDS OR NOT READY YOU WILL FAIL THE INSPECTION

You say you changed the cam sensor. A1391 code is a crank sensor on the top of the trans. bell housing.

These cars are famous for leaky seals where the valve cover interfaces with the cylinder head, at the spark plug journals. They fill with oil, short the coils and cause a misfire. Driving it any significant distance can destroy your catalytic converters ad unburnt fuel ignites therein, creating inferno-like conditions and a fire hazard too. You'll get a "300 code", such as 301 if cylinder 1 is misfiring, 302 for # 2, etc. Pull the coil off the spark plug for that cylinder and if it is moist at all, that's your issue. Have new seals put in, or you'll just keep blowing coils at $50 a whack.

If the air bag light is on there is a problem with the air bag. The light means the air bags will not deploy in an accident. Only a qualified tech should work on air bags.
