Vehicle will not pass emissions inspection, due to check engine light. Code: 02, Cat, EVAP.

Do you have the specific codes you could reply back to me so I can provide better direction and information.
If there is a fault in the O2 sensor then it is usually the sensor(s) but the rear case could be wiring to the sensor(s).
Cataylst issue could be related to the O2 sensors or the cataylitic converter itself.
EVAP issue is either a leak or part failure causing the code

Please provide the exact codes (example P0420, P0201, P0456 etc.)
