If you had the battery disconnected
or any work had been done on and the system was reset
monitors will say its not ready
and you have to drive the car more until they become ready
if you have a bad sensors then check engine light will come on.
If you have check engine light on you need the codes
you can get the codes by cycling the key three times on off ending with key on
or ask your local part store or repair shop for a system scan
most do it for free
